What should be paid attention to when using stainless steel forged flange？

　　In order to improve the corrosion resistance and weldability of stainless steel flange, a proper amount of stable elements such as Ti, Nb and Mo should be added. The weldability of stainless steel flange is better than that of stainless steel flange. When the same type of stainless steel flange welding rod is used, preheating above 200 ℃ and tempering at 800 ℃ after welding shall be carried out. If the weldment cannot be heat treated, stainless steel flange pipe welding rod shall be selected. ANSI Class 150 F304 Stainless Steel Forged Blind Flange, butt welding flange electrode has good corrosion resistance and oxidation resistance, widely used in chemical industry, chemical fertilizer, petroleum, medical machinery manufacturing.
