Cryogenic treatment is to use refrigerant as cooling medium to carry out programmed cryogenic treatment (-196℃) and low temperature tempering on materials, so as to improve and strengthen the performance of metal materials. Cryogenic treatment is a new technology to improve and strengthen the properties of metal materials. Metal in the process of cryogenic processing a large amount of residual austenite into martensite, especially and the stability of the supersaturated martensite in the process can reduce the saturation, carbide dispersion, and keep coherent relationship with matrix of ultrafine carbides, can reduce martensite lattice distortion, microscopic stress is reduced, and at the time of the material to plastic deformation small dispersion carbide can hinder dislocation motion.
ZJCLV cryogenic ball valves are fully in strict accordance with the lasted API version and it’s been rigorously tested.
