Titanium calcium type Cr26Ni21 austenitic stainless steel electrode, molten metal at 900-1100℃ high temperature conditions has excellent oxidation resistance, AC and DC dual use. Good welding technology. The same type of heat resistant stainless steel is used for working at high temperature. It is also used for welding large hardened chromium steels [such as Cr5Mo, Cr9Mo, Cr13, Cr28, etc.] and dissimilar steel.
