Stoodite 21 is a low carbon, molybdenum strengthened cobalt chromium alloy with excellent high temperature strength and stability frequently used in hot die applications. With anti-galling, cavitation erosion, and corrosion resistance, Stoodite 21 is a popular fluid valve seat facing alloy. Certification to AWS specification - A5.21 ERCoCr-E for bare rods; A5.13 ECoCr-E for coated electrodes.
Certification to AWS specification - A5.21 ERCoCr-E for bare rods; A5.13 ECoCr-E for coated electrodes. 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.
