Discuss what is high temperature resistant stainless steel bearing

Many people don't know what is high temperature resistant stainless steel bearing, in this as an introduction to the definition of high temperature resistant stainless steel bearing. Working temperature above 150 ℃ using stainless steel bearing called high temperature resistant stainless steel bearing. Because chromium bearing steel in the use of temperature exceeds 150 ℃ ~ C, its will be a sharp drop in hardness, size change, and lead to high temperature resistant stainless steel bearing cannot work normally. So for working temperature at 150 ℃ ~ E ~ 250 ℃ work under the premise of bearing, if the ring and move the body still choose ordinary high carbon chromium bearing steel manufacturing, is necessary to special tempering treatment of bearing parts, shall generally be higher than under the working temperature of 50 ℃ tempering. Through the tempering treatment according to the requirements of the bearing steel, can be used in normal working temperature. But after tempering hardness decreased, stainless steel bearing life. When the stainless steel bearing operating temperature higher than 250 ℃, is necessary to use high temperature resistant bearing steel manufacturing. High temperature resistant stainless steel bearing has the function of general stainless steel bearing and high temperature hardness and high temperature wear resistance, high temperature and contact fatigue strength, oxidation resistance high temperature function, high temperature impact resistance function and the size is not disorderly. Researchers, high temperature resistant stainless steel bearing vendors and high temperature bearing steel W, Cr, V, Mo and so on can form of undissolved carbide under high temperature, and can precipitate are dispersed carbides during tempering, produce the secondary hardening effect, make this kind of steel under a certain temperature still has high hardness, wear resistance, strong anti-oxidation function, high fatigue resistance and size not disorderly. High temperature bearing steel with Cr4M04V and W18Cr4V is most commonly used; For complex structure, but also bear strong impact load bearing, high temperature carburizing steel can be used. 12 cr2ni3m05 is a kind of function better high temperature carburizing bearing steel, because of its low carbon content ( 0. About 15%) , there is no carbide uneven shortcomings, annealing hardness is low, cutting function is good, has the high toughness and good malleability and can increase the bearing parts of the forging ratio, is beneficial to the service life of bearing, after carburizing can be satisfied under the temperature 430 ~ C use premise, and has the very good impact resistance.
