Semi-martensitic Precipitation Hardened Stainless Steel

Grade：

S-04

Standards and Technical Conditions：

GJB 7961-2012

Product Characteristics

00Cr13Co9Ni5Mo5 is a cast martensitic aging stainless steel with excellent performance, possessing both the corrosion resistance of stainless steel and also the strength and toughness comparable to 18Ni martensitic aging steels. This steel possesses good strength-toughness, corrosion-resistance and oxidation-resistance at high temperature, and good plasticity and toughness at low temperature.

Industrial Application

The alloy's main products are bars. The alloy has been used to manufacture key bearing components of liquid-oxygen/kerosene high-pressure staged-combustion engines, such as: engine oxygen pump housings and liquid oxygen main valve housings, various key structural components of aero engines, centrifugal wheels of turbine oxygen pumps.

Company Product Applications

The bars produced by the Company are applied to aero engine manufacturing.
