(1) Ferrosilicon is an indispensable deoxidizer in the steelmaking industry. In steelmaking, ferrosilicon is used for precipitation deoxidation and diffusion deoxidation. Brick iron is also used in steelmaking as an alloying agent. (2) Used as an inoculant and a nodularizer in the cast iron industry. In the production of ductile iron, 75 ferrosilicon is an important inoculant (helping to precipitate graphite) and nodularizing agent. (3) Used as a reducing agent in the production of ferroalloys. Not only the chemical affinity between silicon and oxygen is very high, but also the carbon content of high silicon ferrosilicon is very low. Therefore, high-silicon ferrosilicon (or siliceous alloy) is a commonly used reducing agent in the production of low-carbon ferroalloys in the ferroalloy industry. (4) 75 ferrosilicon is often used in the high-temperature smelting process of metal magnesium in the Pidgeon process of magnesium smelting. The magnesium in CaO.MgO is replaced, and about 1.2 tons of ferrosilicon are consumed for each ton of metal magnesium produced. Magnesium metal production plays a big role

Special-Shaped Lead Brick Heavy Industry Lead-Antimony Alloy Product Description An antimony-containing lead alloy used in the manufacture of grids and conductive parts for lead-acid batteries. Compared with pure lead, it has a lower melting point, good fluidity in molten state, easy casting and molding, and high hardness after solidification; the disadvantage is that the gas evolution overpotential of the grid is low. In order to reduce the precipitation of gas during charging of the battery, reduce self-discharge and improve corrosion resistance, the antimony content has been gradually reduced from the traditional 5% to 7% to about 2% or even lower. At the same time, a small amount of other components such as tin, arsenic, sulfur, selenium and copper are selectively added to improve the physical and chemical properties of the alloy. Welding temperature 287℃-294℃. According to the welding temperature, the composition ratio is also different. Physical: Lead (Pb99) : melting point 327℃, density 11.34g/cm3.

Alloy Structural Steel Supplier ODM Alloy Structural Steel Supplier Stock 1. Structural alloy steel (structural alloy steel) refers to steel that is used as mechanical parts and various engineering components and contains one or several alloying elements in a certain amount. 2. Alloy structural steel is generally divided into quenched and tempered structural steel and case-hardened structural steel. ① The carbon content of quenched and tempered structural steel is generally about 0.25% to 0.55%. For structural parts of a given cross-sectional size, during the quenching and tempering treatment (quenching and tempering), if it is quenched along the section, the mechanical properties It is good, but if hardenability is not carried out and free ferrite appears in the microstructure, the toughness decreases. For steels with a tendency to temper brittleness, such as manganese steel, chromium steel, nickel-chromium steel, etc., they should be cooled quickly after tempering. The quenching critical diameter of this type of steel increases with the increase of grain size and alloying element content. For example, 40Cr and 35SiMn steels are about 30 to 40 mm, while 40CrNiMo and 30CrNi2MoV steels are about 60 to 100 mm. Structural parts such as shafts and connecting rods with large loads. ②Surface hardening structural steel is used to manufacture parts with hard and wear-resistant surface and flexible core, such as gears, shafts, etc. In order to make the toughness of the core of the part high, the carbon content in the steel should be low, generally 0.12 to 0.25%, and there should be an appropriate amount of alloying elements to ensure suitable hardenability. Nitride steel also needs to add alloying elements (such as Al, Cr, Mo, etc.) that are easy to form nitrides. Carburizing or carbonitriding steel, after carburizing or carbonitriding at 850~950℃, quenched and used in low temperature tempering (about 200℃). Nitrided steel is treated by nitriding (480～580℃) and used directly without quenching and tempering. 3.Production Process According to the steel grade and steel quality requirements, the smelting of alloy structural steel can be carried out by oxygen top-blown converter, open hearth, electric arc furnace; or by electroslag remelting and vacuum degassing. The ingot can be cast by continuous casting or die casting. The ingot should be slowly cooled or hot forged and rolled. When the ingot is heated, the temperature should be uniform and there should be sufficient holding time to improve segregation defects and avoid uneven deformation during forging and rolling; the steel after forging and rolling is small in size, especially carburizing with a carbon content of about 0.2%. Steel should be cooled rapidly at temperatures above 600°C to avoid aggravating the banded structure; for forgings with larger cross-sections, measures should be taken to eliminate internal stress and white spots. Quenched and tempered steel should be quenched into martensite structure as much as possible, and then tempered into sorbite structure; in the carburizing process of carburized steel, the concentration gradient of the carburizing layer should not be too large, so as to avoid continuous network on the grain boundary of the carburizing layer. Carbide; nitrided steel must first be heat treated to obtain the required properties, and then final finishing can be used for nitriding. After nitriding treatment, no processing is required except that the brittle "white layer" is ground and removed. 4. Songshun specialized in Special Steel for almost 20 years.

ASTM 8620 JIS SNCM220 DIN 1.6523 Alloy Structural Steel Application Application What is the application of 8620 steel? AISI 8620 alloy steel is mainly used as a material for impact and wear resistant parts such as automobile bearings, camshafts, etc. In the carburized state it is used for gears, ring gears, shafts and crankshafts.It can also be used for the claws and cone bodies of the roller cone bits for oil drilling and metallurgical open-pit mines, and to manufacture the forgings of the connecting rod valve section of the steam turbine gear whole rotor internal combustion engine. Heat Treatment AISI/SAE/ASTM 8620 Steel Heat Treatment （1）Glow It can be fully annealed by heating to 820 – 850℃ and holding until the temperature is uniform throughout the section, and furnace or air-cooled. （2）Cranking Tempering of heat treated and water cooled parts (not carburized) is done at 400 to 1300 F to improve the toughness of the case with minimal impact on its hardness. This also reduces the possibility of grinding cracks. （3）Hardening It is austenitized at around 840°C – 870°C and oil or water quenched depending on the cross-section size and complexity. And cool it in air or oil required. （4）Normalize 910ºC (1675ºF) and air cooled. This is another method to improve the machinability of 8620 steel materials. Normalizing can also be applied prior to case hardening. （5）Heat treatment This alloy can be hardened by heating to 1500 F and then water quenching. Carburize at 1650 to 1700 F in a suitable carburizing medium and oil quench to harden. Improved properties of the carburized case and core can be obtained by furnace cooling by carburizing at 1650-1700F and then reheating to 1575F. Test How is ASTM 8620 steel tested? Our AISI 8620 alloy steel guarantees high quality, and we use UT test to check each piece of steel; UT test: Ultrasonic Test, ultrasonic inspection and flaw detection, is one of the methods of non-destructive testing in the industry. When the ultrasonic wave enters the object and encounters a defect, a part of the sound wave will be reflected, and the transmitter and receiver can analyze the reflected wave, and the defect can be detected extremely accurately. And it can display the position and size of internal defects, and measure the thickness of materials. Ultrasound in UT is a mechanical wave with a frequency higher than 20 kHz. The frequency commonly used in ultrasonic flaw detection is 0.5 to 5 MHz. This kind of mechanical wave can propagate at a certain speed and direction in the material, and it will be reflected when encountering a heterogeneous interface with different acoustic impedance (such as a defect or the bottom surface of the measured object, etc.).

5140 steel is medium carbon modulation steel, cold heading die steel. The steel is moderate in price, easy to process, and can obtain certain toughness, plasticity and wear resistance after proper heat treatment. Normalizing can promote tissue spheroidization and improve the cutting performance of blanks with hardness less than 160HBS. Tempered at a temperature of 550~570℃, the steel has the best comprehensive mechanical properties. The hardenability of this steel is higher than that of S45C steel, and it is suitable for surface hardening such as high frequency quenching and flame quenching. Heat Treatment AISI/SAE/ASTM 5140 Steel Heat Treatment Heat treatment specification: quenching at 850℃, oil cooling; tempering at 520℃, water cooling, oil cooling 5140 surface quenching hardness is 52-60HRC, flame quenching can reach 48-55HRC Nitriding treatment 1.7035 is a nitridable steel, and the elements it contains are conducive to nitriding. 40Cr can obtain higher surface hardness after nitriding treatment, the highest hardness of 40Cr after nitriding treatment can reach 72~78HRA, and the core hardness can reach 43~55HRC. Nitriding workpiece process route: forging – annealing – roughing – quenching and tempering – finishing – stress relief – rough grinding – nitriding – fine grinding or grinding. Since the nitrided layer is thin and brittle, a high-strength core structure is required, so quenching and tempering heat treatment should be performed first to obtain tempered sorbite to improve the mechanical properties of the core and the quality of the nitrided layer. Weldability of 5140 steel: It is easy to segregate during crystallization, and is sensitive to crystallization cracks (a kind of thermal cracks), and it is easy to crack in arc craters and concave parts of welds during welding. The carbon content is high, and it is easy to obtain a hardened structure (martensitic structure) that is sensitive to cold cracks during rapid cooling. When the cooling rate of the superheated zone is large, it is easy to form hard and brittle high-carbon martensite to embrittle the superheated zone. Welding process points 1. Generally, welding is carried out in the annealed (normalized) state. 2. The welding method is not limited. 3. Use larger line energy to appropriately increase the preheating temperature. Generally, the preheating temperature and interlayer temperature can be controlled between 250 and 300 °C. 4. The welding material should ensure that the composition of the deposited metal is basically the same as that of the base metal, such as J107-Cr. 5. Quenching and tempering heat treatment should be carried out in time after welding. If it is difficult to carry out the quenching and tempering treatment in time, intermediate annealing or holding for a period of time at a temperature higher than preheating can be carried out to eliminate diffusible hydrogen and soften the structure. For products with complex structure and many welds, an intermediate annealing can be performed after a certain number of welds have been welded. If you have any questions,pls feel free to contact us.
