high speed steel composition forged high speed steel composition supplier High-speed steel (HSS) is a tool steel with high hardness, high wear resistance and high heat resistance, also known as high-speed tool steel or front steel, commonly known as white steel. High-speed steel was created in 1898 by F.W. Taylor and M. White in the United States. High-speed steel has good process performance, good strength and toughness, so it is mainly used to manufacture complex thin-edged and impact-resistant metal cutting tools, as well as high-temperature bearings and cold extrusion dies. In addition to the high-speed steel produced by the smelting method, powder metallurgy high-speed steel appeared after the 1960s, which has the advantage of avoiding the reduction of mechanical properties and heat treatment deformation caused by the segregation of carbides produced by the smelting method. Craftsmanship The heat treatment process of high-speed steel is more complicated, and it must go through a series of processes such as quenching and tempering. Quenching is generally carried out in two stages due to its poor thermal conductivity. First preheat at 800 ~ 850 ℃ (to avoid causing large thermal stress), then quickly heat to the quenching temperature of 1190 ~ 1290 ℃ (the actual temperature of different brands is different), and then oil cooling or air cooling or gas cooling. The factories are all heated by salt furnaces, and vacuum furnaces are also widely used. After quenching, a part (about 30%) of retained austenite remains in the internal structure and is not transformed into martensite, which affects the performance of high-speed steel. In order to transform the retained austenite and further improve the hardness and wear resistance, it is generally necessary to carry out 2 to 3 tempering times, the tempering temperature is 560 ° C, and the temperature is kept for 1 hour each time. Production method: Usually electric furnace is used for production, and powder metallurgy method was used to produce high-speed steel, so that the carbides are evenly distributed on the substrate in the form of extremely fine particles, which improves the service life. Uses: used to manufacture various cutting tools. Such as turning tools, drills, hob, machine saw blades and molds with high requirements. Songshun specialized in Special Steel for almost 20 years.

1.m2 steel is molybdenum-based high-speed steel, which has the advantages of small carbide inhomogeneity and high toughness. It is easy to overheat, so the quenching heating temperature should be strictly controlled, and the requirements for heat treatment protection are stricter. Due to its good hardness and wear resistance, it is mostly used to manufacture tools for cutting difficult-to-cut materials. M2 steel has a high tendency to carbides, so it has stricter requirements for heat treatment protection, and is suitable for molds that withstand vibration and impact loads. 2.AISI M2 Steel physical properties Factory hardness: ≤255HB Quenching temperature: 1220-1240 Hardness:≤63 3.1.3343 High Speed Steel Features Hardness (factory state): ≤255HB Curing Temperature: 1220℃-1240℃ Hardness (after heat treatment): ≤ 63 HRC It is a good choice for cutting applications due to its high wear resistance and toughness.

Introduction What is AISI 5140 Steel? AISI 5140 steel also can be called JIS Scr440 and DIN 1.7035 steel.AISI 5140 steel round bar is one of the alloy steel as well as the most popular steel grades in the productions of the machine. The AISI 5140 steel price is on the medium level and it was easy to processing. After tempering and quenching, the toughness, plasticity and wearing resistance of it will get better. Steel normalizing can make the spheroidizing for the organization of steel get easier. And it will raise the machinability of the semi-finished product with the hardness less than 160HBS. Tempering it at the temperature of 550℃-570℃ which can make it get better mechanical property. And the hardenability of it is higher than S45C steel. You can check 5140 Steel chemical composition and mechanical properties as below. use 5140 This steel is quenched and tempered and used to manufacture mechanical parts that are subjected to medium load and medium speed work, such as steering knuckles of automobiles, rear axle shafts and gears, shafts, worms, spline shafts, top sleeves, etc. on machine tools; After quenching and tempering at medium temperature, it is used to manufacture parts that are subjected to high load, impact and medium speed work, such as gears, spindles, oil pump rotors, sliders, collars, etc. Low-impact and wear-resistant parts, such as worms, spindles, shafts, collars, etc., with a solid thickness of less than 25mm on the cross-section; after quenching and tempering and high-frequency surface quenching, they are used to manufacture high surface hardness and wear resistance And parts without great impact, such as gears, sleeves, shafts, main shafts, crankshafts, mandrels, pins, connecting rods, screws, nuts, intake valves, etc. In addition, this steel is suitable for the manufacture of various transmission parts for carbonitriding, such as gears and shafts with large diameters and good low temperature toughness Test How is ASTM 5140 steel tested? AISI 5140 Steel Chemical Composition Testing-Spectrometer We are sae 5140 Alloy Structural Steel for composition testing using spectrometer.The spectrometer one-time excitation of the sample to analyze its composition method is widely accepted by the public at this stage.Compared with traditional analytical methods, the advantages of spectrometers for the detection of modern steel components are fast, accurate and efficient. This method can directly inject solid samples without chemical digestion, which can reduce the human error caused by the digestion process and the constant volume process; to good quality steel.

It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength.   Fabrication and Heat Treatment: 1. Forging Preheat the steel carefully, then raise the temperature to 1150-1200°C for forging. Do not forge below 850°C. 2. Annealing Heat the AISI 4140 slowly to 800-850°C and allow enough time for the steel to be thoroughly heated. Cool slowly in the furnace to 480°C followed by air cooling. 3. Stress Relieving When parts are heavily machined, ground or otherwise subject to cold work, stress relieving will be beneficial prior to hardening. 4. Hardening AISI 4140 steel is usually supplied ready heat treated to 18-22HRC. If further heat treatment is required annealed AISI 4140 should be heated slowly to 840- 875°C and after adequate soaking at this temperature quench in oil. Temper as soon as the tools reach room temperature. 5. Tempering Heat the AISI 4140 carefully to a suitable temperature selected by reference to a tempering chart or table (usually between 550-700°C, soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in air. Tempering between 250-375°C is not advised as tempering within this range will seriously reduce the impact value. 6.

For example, a tensile strength of 225 ksi can be achieved by annealing at 316 °C (600 °F), and a tensile strength of 130 ksi can be achieved by annealing at 538 °C (1000 °F). （11）Hardening Alloy steel according to DIN 1.7225 can be hardened by cold forming or heating and quenching. What is the application of 4140 steel? AISI 4140 steel round bar is an alloy structural steel with good strength and good comprehensive mechanical properties after heat treatment. It has good manufacturability. The maximum operating temperature is 427°C. It is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, and can also be used to manufacture turbine fasteners, tool bodies, dies, brake shoes, etc. Dongguan Songshun Mould Steel Co., Ltd. is an Indusrtial and trading company with 2 warehouses that manufactures good & high quality kinds of steels starting from 2012.
