AWS A5.9 ER 316L Stainless Welding Wire can be used in petrochemical equipment, such as the welding of OOCr17Ni12M02(SUS 316L) materials. Features: The wire is 19%Cr-12%Ni-2%Mo stainless steel wire with ultra-low carbon. It has excellent corrosion resistance to the acetic acid, sulfurous acid, phosphoric acid and salts because it contains Mo. It has stable welding arc, beautiful shape, and can be used for all position welding.

Notes on usage:

1 . Clear rust, oil, water and other impurities on the weldments before welding.

2. It is recommended to use Ar+(1%-3%)02as shielding gas in MIG welding, and use pure argon as shielding gas in TIG welding.

3. The user should develop an appropriate production welding specifications according to the circumstances.
