347 Stainless Steel Plate

347 stainless steel in 400 ~ 900℃ temperature range of high temperature corrosion and oxidation resistance, can be used for the working temperature below 850℃ pipe fittings, widely used in petrochemical, food, paper and thermal power plant, nuclear power industry in the large boiler superheater, reheater, steam pipe, shaft parts, welding structural parts.

347 stainless steel welding performance is good, but also commonly used for welding core and welding tape and other welding materials.
