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
