● Features
Commonly used carburizing steel for the production of bearings. Carburized surface with very high hardness, wear resistance and contact fatigue strength, toughness and heart department, can withstand a strong impact on load, welding the middle, there is tendency to temper brittleness, white point of the formation of the more sensitive.
● Use an example
Large-scale production of high impact load bearing, such as rolling mill bearings, also used for other large carburized parts, such as large gears, shafts, etc., can also be used in the manufacture of high strength and toughness requirements of quenched and tempered conditions.
