Spring Steel Strip & Reite Heat Treatment Spring Steel Heat Treatment Spring Steel Hardness Heat Treatment Spring Steel Price Heat Treatment Spring Steel Manufacturer What is the hardness range of strip steel after heat treatment? After heat treatment, the surface can be baked (blue), black, and bright. It has high hardness and high tensile strength, so the hardness of heat-treated strip steel is also very high. Its hardness range after heat treatment is 0. The heat treatment hardness within this range is widely used. The products are used in machinery, electronics, plastics, hardware, gaskets, mesons, cutting tools and other products that require higher hardness and higher elasticity requirements.
Heat treatment
After oil quenching, the surface of the cold-rolled steel strip spring support will be salty and difficult to clean. It will easily rust after being stored for a long time. It is not easy to weld during spot welding in the next process. In order to solve this problem After the workpiece is quenched and tempered, and before spot welding is used in the next step, the principal support is sandblasted to make the surface of the workpiece clean and easy to spot weld, and meets the technical requirements of the workpiece.
The carbon content is .%~.%, and the contents are .%~.% and .%~.% respectively. Moving the midpoint and point of the iron-carbon phase diagram to the lower left lowers the sum line. Therefore, manganese steel has a tendency to overheat. Cold-rolled strip steel is a high-carbon steel, and with the combined effect of and, its carbon equivalent reaches more than .%. This gives cold-rolled strip steel a great tendency to harden and has extremely poor weldability.
