Low Carbon Steel Welding Electrode E-316

E316

AWS A5.4 E316-16

Explain:

E316 is a Cr18Ni12Mo2 stainless steel electrode with titanium calcium based coating. As deposited metal is added with Mo, it has good corrosion resistance, heat resistance and crack resistance, especially against pitting corrosion of chloride ion. It can be used both AC and DC, and has excellent operation performance.

purpose:

Used for welding in organic and inorganic acid (non oxidizing acid) medium and 06Cr17Ni12Mo2 stainless steel or as dissimilar steel welding.

Matters needing attention:

1.The electrode must be baked at 300ºC 1H before welding.

2.As far as possible the use of DC power supply, the current should not be too large.
