1.4362 duplex stainless steel Tube Bright Annealed 25.4 X 1.65MM TIG Welded High Strength

1.4362 duplex stainless steel Tube Bright Annealed 25.4 X 1.65MM TIG Welded High Strength


UNS S31803 Duplex stainless steel welded tubeis a duplex (austenitic-ferritic) stainless steel containing about 40 - 50% ferrite in the annealed condition. 2205 has been a practical solution to chloride stress corrosion cracking problems experienced with 304/304L or 316/316L stainless. The high chromium, molybdenum and nitrogen contents provide corrosion resistance superior to 316/316L and 317L stainless in most environments. S31803 is not suggested for operating temperatures up to 600°F.

The design strength of 2205 is significantly higher than 316/316L, often permitting lighter wall construction. 2205 has good notch impact toughness down to temperatures below - 40°F. 2205 is welded with E2209 or ER2209 fillers.
