Quench craze reason is reached avoid measure

Crackle type feature forms a condition to avoid measure fore-and-aft crackle is reached by the watch in, deep and long temper by dipping in water shows work easy happening, raw material has carbide banding slant analyse or metalloid field trash are outspread quality of control raw material, logical choice conditioning treatment often is located in workpiece corner office with improving crackle of primitive organization arc, concealed issues easy at happening at expressing facing not temper by dipping in water shows work or cementite quenchs a change workpiece is design, sectional transfer meshy crackle is located in round horn rationalize workpiece surface, deepness decarbonization of surface layer of 0.01 ~ 2mm, thermo-chemical treatment and surface quench easy appear, avoid decarbonization, defer quench cooling, reduce quench temperature comes off craze expression comes off for hard layer of temper by dipping in water the surface quenchs or thermo-chemical treatment logical choice medium, defer refrigeration to show micro-crack to quench in microstructure blemish place a tall carbon martensite avoid to heat near the needle overheat and grain are bulky
