EMBRITTLEMENT AVOIDANCE ***TO BE USED WITH FORD WSS-M99P1111-A***

active, Most Current
Organization: FORD
Publication Date: 7 April 2022
Status: active
Page Count: 7
scope:

This specification outlines the conditions that enhance the embrittlement risk of steel components, steel and aluminum fasteners, and cast iron. Mechanisms include hydrogen embrittlement, stress corrosion cracking, intergranular corrosion, and liquid metal embrittlement. The specification identifies requirements intended to minimize that risk.
