Specification: AWS-E312
Available forms: E , FC , TIG , MIG

 


Polystain® 316 (AC/DC) - Recommended for welding type 316 stainless steel and other alloys requiring high-temperature service. The addition of molybdenum reduces pitting by some acids and enhances elevated-temperature properties. Uses include fabrication and cladding in the petroleum, paper and chemical industries for piping, pulp digestors, tanks and vats.

Specification: AWS-E316
Available forms: E , FC , TIG , MIG

 


Polystain® 317 (AC/DC) - Similar to Polystain® 316 exept that the higher alloy content, particularly molybdenum, gives extra creep strength, corrosion resistance and added protection when welding types 316, 316-L and 317 stainless steel. Uses include weldments to resist corrosion caused by sulfuric and sulfurous acids. Used extensively in the chemical, paper and textile industries where fabricated equipment is subject to temperatures up to 1,300F.

Specification: AWS-E317
Available forms: E , FC , TIG , MIG

 


Polystain® 330 (AC/DC) - For welding cast or wrought forms of type 330 stainless steel with excellent heat and creep resistance. Uses include the fabrication and repair of heat-treating equipment, furnace components and many other high-temperture applications.

Specification: AWS-E330
Available forms: E , FC , TIG , MIG

 


Polystain® 3320 (AC/DC) - For fabricating Carpenter® 20 and 20CB-3. This alloy offers superior resistance to high temperatures and chemical corrosion. A low residual "LR" version is also offered.
