AMS5790C - Steel, Corrosion and Heat-Resistant, Welding Wire 20Cr - 10Ni - 0.75Cb, High Ferrite Grade

Details Document Number: AMS5790C Revision Number: C Title Steel, Corrosion and Heat-Resistant, Welding Wire 20Cr - 10Ni - 0.75Cb, High Ferrite Grade Scope This specification covers a corrosion and heat resistant steel in the form of welding wire.<p>This wire has been used typically as bare wire filler metal for gas-tungsten-arc or gas-metal-arc welding of corrosion and heat resistant alloys of similar composition, but usage is not limited to such applications.<p>The relatively high ferrite content promotes weldability by combating microfissuring and minimizing cracking in heavy sections but limits use of the wire to applications not operating in the sigma-forming temperature range, approximately 1100 to 1600 degrees F (590 to 870 degrees C).
