Whats the hardness of S45C after heat treatment s40c after tempering hardness

The hardness is not more than HRC40, the best is 35 to 38. Such as shafts, gears, are S45C quenching and tempering HRC35 ~ 36. The Max. hardness of S45C can be up to HRC60, but its too brittle, so its meaningless. After quenching, tempering for S45C at 150-250 temperature, the hardness is up to HRC50 above, but the toughness is poor, rarely used in production.What is tempering and case hardening?Tempering is a low temperature heat treatment process normally performed after a hardening process in order to reach a desired hardness/toughness ratio. Case hardening is the process of hardening the surface of a metal by infusing elements into the materials surface, forming a thin layer of harder alloy.See all results for this questionWhat is s40c steel?S40C steel plate is one mainly of high carbon steel, S40C has high strength and good machinability, cold plastic deformation of medium, good weldability, after quenching and tempering after welding, heat treatment, no temper brittleness, but lower hardenability.See all results for this question

Aug 04, 2020 · Tempering Steel after hardening Definition. Tempering steel process after hardening is the heat treatment process carried on as-quenched steel to a temperature that is lower than a lower critical temperature line to induce ductility and toughness. In general, heat treatment is carried out to bring balance between hardness and toughness.Tempering - temperature/time Relationship | BladeForums s40c after tempering hardnessSep 16, 2017 · Basic carbon steels will lose too much hardness in a high temper, so unless a specific toughness is the desired target ( like a spring), the temper is usually kept as low as needed for the desired target hardness. Normal tempering for basic carbon steels and low alloy steels is 350F-550F. This balance between toughness and hardness is what s40c after tempering hardnessTempering - Hardening and tempering - Bodycote PlcThe hardness will vary from 300HB to 65HRC dependent on the material.
