All stainless steel chassis beautiful and durable, high-quality high-density polyurethane foam insulation layer insulation. System, reasonable structure, manufacturing process specifications, components compact layout, simple functions operate powerful, user-friendly interface exchange; equipment to liquid nitrogen as a cooling medium, 5 minutes rapid cooling, the lowest temperature can reach -196 ℃. Goldman cryogenic tank temperature control and high accuracy, the use of safe, convenient, economical and environmentally friendly. Liquid nitrogen cryogenic treatment: cryogenic process can improve the performance of metal materials the most effective and economical technical indicators, martensite in cryogenic process, so that residual austenite, and the dispersed carbide material change in performance may impede dislocation motion of ultra-fine carbide precipitation, thereby strengthening the matrix structure, to play the role of grain boundary strengthening, improved the following three areas: toughness, wear resistance, dimensional stability. An improved hardness, high speed steel, tool steel Rockwell hardness increased by 1 to 2 degrees 2, improve the wear resistance of steel wear Cr12MoV increase 30%, 20Ni3Mo steel hardened steel wear resistance increased 89% 3, to improve the degree of bending flexural strength 1135MPa 440A from cast stainless steel up to 1355MPa 4, to improve the toughness W6Mo5Cr4V2 18J impact energy from up to 40J. 5, to improve red hardness W18Cr4V 625 ℃ under the conditions of Rockwell hardness increased from 57.9 to 63.9. 6, improve the dimensional stability of retained austenite stainless 95Cr18 reduced to 10% from 35%. 7, to improve the conductivity of copper alloy Cu_15Ni_8Sn resistivity from 2.86 × 10-7Ω.m reduced to 1.51 × 10-7Ω.m.
