MasterWeld MW19-10H Stainless Steel TIG Welding Rods
MasterWeld MW19-10H Stainless Steel TIG Welding Rods are for welding nominally 18%Cr-8%Ni austenitic stainless steel base materials with carbon ≥0.04%. MW19-10H is not used for corrosion resisting applications but for high temperature applications where good oxidation resistance and creep strength are required. Typical applications include petrochemical plant
eg. cat crackers. Typical service temperatures up to ~800°C.
