Why Cold Steel Is Brittle - Knife Steel Nerds

Low and High Tempering of Steel#0183;Rather than tempering down to a lower hardness,use a lower carbon steel.Using a steel that is at a higher toughness to begin with (higher fracture strength) will also lead to higher low temperature toughness.Buying steel with minimal impurities and nickel additions also help with improving low temperature toughness.What Happens During Tempering of Steel? - Knife SteelApr 23,2018 Low and High Tempering of Steel#0183;Especially in high alloy steels with a low tempering temperature (400 Low and High Tempering of Steel#176;F).See the chart of retained austenite vs tempering temperature for the 1.25% Cr steel and the 5Cr-2.3Mo steel,where even the low alloy 1.25% Cr steel still has some retained austenite after a 400 Low and High Tempering of Steel#176;F temper.The high alloy steel see almost no transformation at 400 Low and High Tempering of Steel#176;F.Tempering of steel SpringerLinkTempering of martensitic steels involves the segregation of carbon,the precipitation of carbides,the decomposition of retained austenite,and the recovery and recrystallization of the martensitic structure.Because these several reactions overlap and occur on such a fine scale,it is only recently that our knowledge of the resulting structures has become reasonably complete.
