Mastering the S7 Tool Steel Heat Treatment: A Comprehensive Guide to Achieving Peak Performance
S7 tool steel is an impact-resistant tool steel. Its greatest advantage is exceptional impact resistance. A characteristic of S7 steel is its “air-hardening” capability. After heat treatment, it can be hardened by cooling naturally in air, rather than requiring immersion in oil or water. S7 exhibits excellent dimensional stability during machining, resisting deformation or cracking. […]
