Stoodite 21-S
Stoodite 21-S has excellent high temperature strength making it suitable for use on hot die parts. The deposits are inherently resistant to galling, cavitation erosion, and corrosion. Although abrasion resistance is a bit lower than other Stoodite wires, 21-S exhibits outstanding impact strength at high temperatures, anti-galling properties, and corrosion resistance. Certification to AWS specification - A5.21 ERCCoCr-E
Features
Certification to AWS specification - A5.21 ERCCoCr-E. Stoodite cobalt base alloys are manufactured to conform to the chemistry and usability requirements of the specifications noted. Certification to ASME and MIL must be requested at the time order is placed and must appear on the written P.O. Additional charges apply for military, nuclear, or special certification requirements.
- Excellent high temperature strength
- Galling, cavitation erosion, and corrosion resistant
- High impact strength
