Stainless Bearing Steel Tubes

China [CN] Stainless steel bearings are mainly used in corrosion resistant and heatresistant environment. The raw material is martensitic stainless steel including mediumcarbon martensitic stainless steel like 30Cr13and highcarbon martensitic stainless steel like 9Cr18，9Cr18MoV. Due to low carbon content, after quenching the hardness of medium-carbon martensitic stainlss steel is not so high which makes the wearresistance lower, so it mainly used to produce bearings used in 400 degrees corrosion resistant environment. Both of carbon and chromium content of high-carbon martensitic stainless steel are very high, after quenching the hardness, wear-resistance and corrosion resistance is very high which have good stainlessness corrosionresistance and heatresistance in water, atmosphere and some acids and salts solutions. The products mainly used in chemical industry, food hygiene, medical equipment and high temperature/ corrosion environments.
