SAE AMS6475L-2018 PDF

Scope: Form This specification covers an age hardenable nitriding grade of aircraft-quality@ low-alloy steel in the form of bars@ forgings@ mechanical tubing@ and forging stock. Application These products have been used typically for nitrided parts requiring highest surface hardness@ high core hardness@ resistance to heat@ and less distortion than parts made from steel requiring quenching to case harden@ but usage is not limited to such applications.
