SUPER DUPLEX 2205

UNS S31803 W.Nr.104462


S31803 Duplex Stainless Steel Description

S31803 duplex stainless steel yield strength is twice the austenitic stainless steel, this feature allows designers to reduce the weight of the design of the product, so that the alloy than the 316,317 L more price advantage. This alloy is particularly suitable for temperatures up to -50 ° F / + 600 ° F. This type of alloy can be considered beyond the application of this temperature range, but there are some limitations, especially when applied to welded structures.
