Product Description

We know that some metal materials have retained austenite up to 25% or even higher after conventional heat treatment. Excessively high retained austenite will reduce the wear strength of the material, and will reduce the already stable austenite when stimulated by external forces. It becomes unstable and forms primary martensite, which deteriorates the material properties, causes volume expansion and cracks, and seriously affects the dimensional accuracy. Cryogenic treatment is particularly important at this time:

can precipitate ultra-fine carbides to improve the properties of the workpiece.
can refine the grains and improve the impact toughness of the workpiece.
can transform the Paralympics, improve the hardness and performance of the workpiece, and stabilize the size of the workpiece.
can double the corrosion resistance of martensitic stainless steel and improve the polishing performance of the workpiece.
can improve the conductivity and corrosion resistance of non-ferrous metals.

Cryogenic treatment equipment can reduce mold deformation and cracking. Improve the dimensional accuracy of the workpiece. These are the purposes of cryogenic treatment of metallic materials.
