SAE AMS2453A PDF

The purpose of this specification is to establish requirements of a grinding method and to provide grinding parameters that will eliminate or minimize overheating, cracking, high residual tensile stresses, and/or other metallurgical changes that decrease structural integrity of steel parts or chrome plated steel parts (see 8.3). This standard establishes requirements for low stress grinding of martensitic high strength steel heat-treated to 180 ksi (1241 MPa) minimum ultimate tensile strength (UTS) and above, and requirements for low stress grinding of chromium plating applied to such high strength steel.

This process has been used typically to grind chrome plating on high strength steel and high strength steel parts heat treated to 180 ksi (1241 MPa) ultimate tensile strength and above for applications requiring wear, heat, and corrosion resistance or dimensional restoration, such as aircraft landing gear and hydraulic actuator components. However, usage is not limited to such applications (see 8.3).
