316L 6mm Stainless Steel Plates 1D Heat Annealed AMS 5507 Type 316 Austenitic Stainless Steel Sheets Metal AMS 5507 Flat rolled No.1 or 2B overview ASTM A240 Type 316 is the second-most common stainless steel next to 304. Stainless Steel Sheet Type 316 generally contains 16% chromium and 10% nickel, with the addition of molybdenum normally ranging from 2-3%. Molybdenum increases corrosion resistance, particularly against chlorides and other industrial solvents. While there may be a difference between the chemical compositions of SA 240 type 316L Perforated Sheet and 304, their mechanical properties are similar. ASTM A240 Grade 316 Chequered Plate is commonly used in many industrial applications involving processing chemicals, as well as high-saline environments such as coastal regions and outdoor areas where de-icing salts are common. Due to its non-reactive qualities, 316 Stainless Steel Strip & Mesh Sheet is also used in the manufacture of medical surgical instruments. 316 Stainless Steel is more corrosion resistant than grade 304 and is suitable for marine and coastal applications.

Also known as wind steel or front steel, also known as white steel. It means that when quenched, it hardens even when cooled in air and is sharp. It is a complex alloy steel containing carbide-forming elements such as tungsten, molybdenum, chromium, vanadium, and cobalt. The total amount of alloying elements is about 10 to 25%. It can still maintain high hardness under high heat generated by high-speed cutting (about 500 ℃), and the HRC can be above 60. This is the most important characteristic of high-speed steel - red hardness. After quenching and low-temperature tempering, carbon tool steel has high hardness at room temperature, but when the temperature is higher than 200 °C, the hardness drops sharply, and the hardness at 500 °C has dropped to a similar level to the annealed state. , completely lost the ability to cut metal, which limits the use of carbon tool steel to make cutting tools. High- speed steel, due to its good red hardness, makes up for the fatal shortcomings of carbon tool steel and can be used to manufacture cutting tools. High-speed steel generally does not do tensile strength testing, but mainly metallographic and hardness testing. After the correct heat treatment of tungsten and molybdenum high-speed steel, the Rockwell hardness can reach above 63, and the cobalt high-speed steel is above 65. The acid leached low-magnification structure of the steel shall not have shrinkage cavities and skin turns visible to the naked eye. The center is loose, and the general looseness should be less than grade 1. The content of metallographic inspection mainly includes three items: decarburization layer, microstructure and carbide inhomogeneity. 1. High-speed steel should not have obvious decarburization. The microstructure must not have fishbone-like eutectic ledeburite. 2. Carbide inhomogeneity in high-speed steel has the greatest impact on quality, and the metallurgical and mechanical departments attach great importance to the level of carbide inhomogeneity. Different grades of carbide non-uniformity requirements can be put forward according to different uses of steel, and usually should be less than grade 3. 3. In addition to high hardness, high wear resistance and sufficient toughness, another important factor is the red hardness of high-speed steel for manufacturing cutting tools. (Red hardness refers to the ability of the cutting edge to resist softening under red heat when the tool is cutting at high speed.) One way to measure the red hardness is to first heat the steel to 580-650°C, keep the temperature for 1 hour, then cool it down, and measure its hardness after repeating this for 4 times. The quenching temperature of high-speed steel is generally close to the melting point of the steel. After quenching, it is generally necessary to temper 3 times between 540 and 560 °C. Increasing the quenching temperature can increase the red hardness of the steel. In order to improve the service life of high-speed steel tools, the surface can be strengthened, such as low-temperature cyanidation, nitriding, sulfur-nitrogen infiltration, etc. songshunmoldsteel41404340

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. 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 in the manufacture of various cutting tools. Such as turning tools, drills, hob, machine saw blades and molds with high requirements.

What is high hardenability? It indicates that the ability of steel to obtain the depth of the hardened layer when quenched under certain conditions is mainly affected by the carbon content and alloying elements in the austenite. It indicates that the ability of steel to obtain the depth of the hardened layer when quenched under certain conditions is mainly affected by the carbon content and alloying elements in the austenite. Hardenability: refers to the characteristics that determine the hardening depth and hardness distribution of steel under specified conditions. The hardenability of steel is good or bad, which is usually expressed by the depth of the hardened layer. The greater the depth of the hardened layer, the better the hardenability of the steel. Namely high hardenability!! The hardenability of steel mainly depends on its chemical composition, especially the alloying elements and grain size that increase the hardenability, heating temperature and holding time and other factors. The steel with good hardenability can obtain uniform mechanical properties of the entire section of the steel, and a quenching agent with a small quenching stress of the steel can be selected to reduce deformation and cracking. songshunmoldsteel41404340
