Model Number: XYB---Martensitic Stainless
Brand Name: XYB
Key Specifications/Special Features:
Taian Xinyuan Precision Steel Ball Manufacturing Co.,LtdDescriptions:The stainless steels (>12% Cr) of this type are provided with the martensite structure when quenched and their corrosion resistance is rather inferior, but better mechanical properties, as compared with the austenitic stainless steels. This feature makes them especially useful for ball bearings and valve applications.Hardness:AISI 420C: HRC 52-60
AISI 440C: HRC 58-65
Feature:
- AISI 420C:High Hardness, Corrosion and heat resistant
- AISI 440C:With more rust, corrosion performance, enhanced hardness, wear resistance increased
- AISI 420C: 65
- AISI 440C: 75
