Stoodite 1 has the highest hardness of the standard Stoodite cobalt alloys and is used in elevated temperature wear applications. It has a large volume of chromium carbides in a cobalt matrix, giving the alloy excellent resistance to abrasion and solid particle erosion. Stoodite 1 is non-magnetic and non-forgeable, and can be machined with difficulty using carbide tools. It bonds well with stainless and other weldable alloy steels. Certification to AWS specification - A5.21 ERCoCr-C for bare rod; A5.13 ECoCr-C for coated electrode.
Certification to AWS specification - A5.21 ERCoCr-C for bare rod; A5.13 ECoCr-C for coated electrode. 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 abrasion and solid particle erosion resistance
