Description
Cobalt #21 coated electrodes deposit a low austenitic cobalt type alloy with excellent work hardenable high temperature, strength, and impart resistance. It is a good choice for valve trim and steam and fluid control valve bodies and seals. It bonds well to all weldable steels, including stainless.
