9Cr18, 9Cr18Mo stainless steel ball
9Cr18 is high carbon and high chromium martensite stainless bearing steel. After quenching, it has high hardness and wear resistance, high dimensional stability, generally used after quenching and tempering.
9Cr18Mo has the same characteristics and application as 9Cr18 steel, but has higher hardness and stability after quenching. Molybdenum can increase the passivation effect of stainless steel.
