Steel, Corrosion and Heat-Resistant, Welding Wire 20Cr - 10Ni - 0.75Cb, High Ferrite Grade
- Aerospace Material Specification
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).
Data Sets - Support Documents
The committee of Corrosion and Heat Resistant Steels and Alloys and Specialty Steels and Alloys, AMS Committee F, will prepare, coordinate, and revise documents related to corrosion and heat resistant steels and alloys and specialty steels and alloys technology, such as stainless steels and nickel and base alloys, through the participation of metals suppliers, users, and interested government agencies. Committee activities shall provide a forum for the cooperative interchange of ideas and experience of the participants, resulting in the publication of specifications that embody sound, established aerospace industry practices and requirements to serve the suppliers and customers of aerospace materials.
