What is the Best Oil for Quenching Knife Steel? - KnifePath

#50 quenching oil comes close to matching the quench speed of water.However,#50 will give you a less severe and a much more uniform quench that water will.This is a good quenchant to use with 1095 high carbon steel.AAA quenching oil is the most popular and widely used quenchant offered by Park.What is Quenching? Why Steel Needs to be Quenched?The purpose of quenching is to transform the undercooled austenite into martensite or bainite to obtain martensite or bainite structure; quenching associated with tempering at different temperatures can significantly improve the steel rigidity,hardness,wear resistance,fatigue strength,toughness etc.,enabling the steel to meet various requirements of different mechanical parts and tools.What is Quenching?
