9Cr18 is a high carbon and high chromium martensite stainless steel providing high hardness and wear resistance. 9Cr18Mo adds Molybdenum to increase passivation and stability after quenching.
Featuring high toughness, rigidity, and self-lubricity, ZrO2 balls are ideal for valve components in petrochemical and metallurgical applications.
Specializing in high-precision and unique bearing products, our facilities produce components from 0.6mm inner diameter to 6.8m outer diameter. We maintain a leading position in bearing design, lubrication technology, and material research.
