Steel, Corrosion and Heat-Resistant, Welding Wire 20Cr - 10Ni - 0.75Cb, High Ferrite Grade
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 corrosion and heat resistant alloys of similar composition, but usage is not limited to such applications.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).
AMS5790D results from a Five Year Review and update to revise reference to the DeLong Diagram (2.3, 3.1.3) and Reports (4.4).
