9CR18MO belongs to the national standard high-carbon high-chromium horse austenite stainless steel. 9CR18MO execution standard: GB/T 1220-2007 9CR18MO has high hardness and wear resistance after quenching, high high temperature, low temperature size stability, suitable for manufacturing for manufacturing Bearing, rivers, nitric acid, steam, and marine corrosive media, such as bearings in ships, submersible pump components, bearing in petroleum and chemical machinery, navigation instrument bearings, etc. 9cr18mo chemical composition is as follows:
95CR18 (9CR18) Steel is a high -carbon high -chromium macaronic stainless steel, which is improved compared to CR17 -type macaronoscular stainless steel. Other performance is similar to CR17 -type Marbia steel, but low carbon stainless steel difference is low. It has excellent stainlessness and corrosion resistance in the atmosphere, water, and certain acids and salt water solutions. The thermal treatment of 95CR18 (9CR18) Steel generally uses quenching low temperature recovery. It has high hardness, abrasion resistance and corrosion resistance after thermal treatment. 95CR18 (9CR18) Steel is suitable for plastic molds, stainless steel rolling ball bearings, and shafts, pumps, valves, rods, spring parts, fasteners, etc. 95CR18 (9CR18) Steel is Lai’s steel steel, which is easy to form uneven carbonized bias analysis and affects the service life of the workpiece. It is necessary to pay attention when production and selection, especially during hot processing. Processing ratio. 95CR18 Chemical ingredients:
