We are experiencing severe damage to the SS-316 material piping at the outlet of the sulfuric acid storage vessel. No matter what kind of flux on the welding consumables have a corrosive, corrosive size and high activity flux in the operation of electronic butt has really improved weldability weldments corrosion is also very. Stress Corrosion Cracking Locations. Best alloy to use as universal weld filler metal to resist corrosion of weldments. Stainless steel washers fail occasionally because of weld- related corrosion. Stress relieving of martensitic or ferritic stainless steel weldments will simultaneously temper weld and heat affected zones, and for most types will restore corrosion resistance to some degree.
