S31803/F51/DIN 1.4462 Duplex Stainless Steel Description
S31803/F51/DIN 1.4462 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.
The application area
Pressure vessels, high pressure storage tanks, high pressure pipes, heat exchangers (chemical processing industry).
· Oil and gas pipeline, heat exchanger pipe fittings.
· Sewage treatment system.
Pulp and paper industry classifier, bleach equipment, storage processing system.
· High-strength corrosion-resistant environment of the rotary shaft, press roll, blades, impeller and so on.
