Stainless Steel - Grade 416 (UNS S41600)
Grade 416 steel is a free-machining stainless steel with a machinability of 85%, highest of all stainless steels. With most of the free-machining stainless steels, the machinability can be improved by adding sulphur, which leads to the formation of manganese sulphide inclusions. Addition of sulphur also reduces the formability, weldability and corrosion resistance of 416 steels to below that of grade 410.

Heat Treatment of Tool Steels | Metallurgy for Dummies
Preheating, or slow heating, of tool steels provides two important benefits. First, most tool steels are sensitive to thermal shock. A sudden increase in temperature of 1500/2000°F may cause tool steels to crack. Second, tool steels undergo a change in density or volume when they transform from the as-supplied annealed microstructure to the high temperature structure, austenite. If this volume change occurs nonuniformly, it can cause unnecessary distortion of tools, especially where differences in sectioSee more on metallurgyfordummies en p690ql2 steel property Heat treatmentHEAT TREATMENT ON EN 8 & EN 353 FOR HEAVY DUTY Hardening refers to the heat treatment of steel which increases its hardness by quenching.
