Welding 317L 2205 LR DIN Stainless Steel Bends Elbows
2205180 LR Seamless Pipe Fittings Elbow Stainless Steel For Oil And Gas Pipelines
The yield strength of 2205 duplex stainless steel is more than twice that of ordinary austenitic stainless steel. This feature enables designers to reduce weight when designing products, making this alloy more cost-effective than 316 and 317L. This alloy is especially suitable for the temperature range of -50°F/+600°F. For applications beyond this temperature range, this alloy can also be considered, but there are some limitations, especially when applied to welded structures.
The high strength and corrosion resistance of 2205 duplex steel make it have high corrosion fatigue strength. Processing equipment is susceptible to corrosive environments and loading cycles, and the characteristics of 2205 are very suitable for such applications.
