Preheat to 760oC – 820oC, then heat slowly and uniformly to 1050oC – 1150oC, hold until temperature is uniform throughout the 440c steel section and commence forging immediately. Do not overheat 440c stainless steel as this can cause a loss of toughness and ductility. Do not forge below 900oC. Finished forgings of SS 440c should be cooled slowly in a furnace, warm dry lime or ashes to room temperature and annealed immediately. Air cooling after forging may cause cracking of steel 440c.
ASTM Grade 440C stainless steel can be machined well, with all operations such as turning and drilling etc., in the annealed condition. Because of 440C SS high carbon content it machines somewhat like high-speed steel. Because chips are tough and stringy, chip curlers and breakers are important.
As heat treated, the 440 steel series are difficult to machine because of their high hardness. For parts that require extensive machining, the free-machining versions, Type 440F or Type 440F Se, offer improved machining properties.
