Background technology
As China's coal machine and manufactures technology is lifted rapidly with production capacity, with the coal consumption of China first and exploitation big country
Status is consistent, and China has become the first in the world coal machine and manufactures big country.Bearing is to allow between two parts be limited relatively
The device of motion.Roll shaft parts contract containing interior raceway and outer raceway and the rolling part being largely disposed there between (
Ball or roller).For long-term reliability and performance, it is important that different parts are to rolling contact fatigue, abrasion and compacted
Becoming has high tolerance.
Depending on required product made from steel application, modern steel is manufactured using the various combinations of iron and alloying element.Chromium is normal
Alloying element, for against corrosion and rust-proofing.Stainless steel and surgery stainless steel include the chromium that minimum is 10%.
One example of stainless steel composition is the N360 ladles containing 0.30 weight % carbon (C), 0.60 weight %
Silicon (Si), 0.40 weight % manganese (Mn), 15.00 weight % chromium (Cr), 1.00 weight % molybdenums (Mo) and 0.40 weight
Measure % nitrogen (N).The steel is erosion-resisting, martensitic hardening stainless steel, and which show high rigidity and compression strength.
The invention provides a kind of coal mine machinery bearing high strength steel material.
