Welding Properties and Notice: Low carbon and Nitrigon, Titanium and Niobium added, high corrosion-resisted performance on welding parts. Difficult for Fusion wedding and etter for filler wire welding. Low thermal expansion coefficient-high heat conduction and small deformation after welding co***ring with 304. Try to avoid heat imputing, otherwise result in bigger crystalline grain and influent the toughness of the plate. Gas protection: Argon protection is needed to avoid surface oxidization and nitrizing. To Avoid the contanmination of grease, othe |
