WebS2 tool steels can be cold worked under annealed conditions. Annealing. Annealing is performed on S2 tool steels at 788ºC (1450ºF) followed by cooling in the furnace at a rate of not more than 4ºC per hour. Tempering. S2 tool steels are tempered at 177 to 427ºC (350 to 800ºF) to obtain Rockwell C hardness of 60 to 50. WebThe hardenability of a metal alloy is the depth to which a material is hardened after putting it through a heat treatment process. It should not be confused with hardness, which is a …
WebThe hardness scale of metals depends on which property is key to a given application. Steel and its alloys. Steel is a tough alloy of iron and carbon with admixtures of other elements, including silicon, manganese, vanadium, niobium, etc. Various alloying techniques can help produce steels with completely different properties. WebThe hardness may also be shown as XXX HB YYD 2. The XXX is the force to apply (in kgf) on a material of type YY (5 for aluminum alloys, 10 for copper alloys, 30 for steels). Thus a typical steel hardness could be …
