Product Code:SAE AMS5812
Title:Steel, Corrosion and Heat Resistant, Welding Wire, 15Cr - 7.1Ni - 2.4Mo - 1.0Al, Vacuum Induction Melted
Issuing Committee:Ams F Corrosion Heat Resistant Alloys Committee
Scope:This specification covers a corrosion and heat resistant steel in the form of welding wire.This wire has been used typically as bare wire filler metal for gas-tungsten-arc or gas-metal-arc welding of critical weldments of precipitation-hardenable, corrosion and heat resistant steels of similar composition where the weld area is required to have comparable strength and corrosion resistance to that of the parent metal, but usage is not limited to such applications.
