Stainless steel flanges, in order to improve corrosion resistance and weldability, appropriately increase the amount of stability elements Ti, Nb, Mo, etc., the weldability is better than the chrome stainless steel flange. When using the same type of chrome stainless steel flanged electrode (G302, G307), preheating at 200 °C or higher and tempering at around 800 °C after welding should be carried out. If the weldment cannot be heat treated, stainless steel flanged pipe welding rod (A107, A207) should be used.
Stainless steel flanged pipe fittings, butt welding flange welding rods have good corrosion resistance and oxidation resistance, and are widely used in chemical, fertilizer, petroleum, medical machinery manufacturing.
