2205 Duplex Stainless Steel Pipe Description<\/strong><\/b><\/h2>\n

2205\u00a0Duplex stainless steel\u00a0pipe has\u00a0more than twice of yield strength\u00a0than\u00a0ordinary austenitic stainless steel, and it has enough plastic toughness required for molding. 2205 duplex stainless steel has excellent corrosion resistance. Because it contains 22% chromium\u00a0and\u00a03% molybdenum, it can show better corrosion resistance than 316L and 317L in most environments. This alloy also performs well when it comes to localized corrosion resistance. In oxidizing and acidic solutions,\u00a02205\u00a0Duplex stainless steel\u00a0pipe is\u00a0highly resistant to pitting and crevice corrosion.\u00a0Moreover, when compared with austenitic stainless steel with similar alloy content, its wear corrosion resistance and fatigue corrosion performance are better than austenitic stainless steel. Whether under dynamic load or static load conditions, 2205 duplex stainless steel has a higher energy absorption capacity than austenitic stainless steel, which has obvious advantages for structural parts to cope with emergencies such as collisions, explosions, etc..<\/p>\n
