1.4462 Duplex Stainless Steel Casting

Duplex stainless steels are a family of stainless steels. They are designed to provide better corrosion resistance, particularly chloride stress corrosion and chloride pitting corrosion, and higher strength than standard austenitic stainless steels such as Type 304 or 316. The main differences in composition, when compared with an austenitic stainless steel is that the duplex steels have a higher chromium content, 20–28%; higher molybdenum, up to 5%; lower nickel, up to 9% and 0.05–0.50% nitrogen. Both the low nickel content and the high strength (enabling thinner sections to be used) give significant cost benefits. They are therefore used extensively in the offshore oil and gas industry for pipework systems, manifolds, risers, etc and in the petrochemical industry in the form of pipelines and pressure vessels. In addition to the improved corrosion resistance compared with the 300 series stainless steels duplex steels also have higher strength.

EN 1.4462 duplex stainless steel casting is one of the stainless steel casting product lien we developed for our clients, it also called 2205, X2CrNiMoN22-5-3 is its steel designation. This is the typical Standard duplex (PREN range: 28–38) that has been widely used.

Auwell starts development of 1.4462 duplex stainless steel casting products 15 years ago for a German client for swimming pool facility. After casting, we also made machining in accordance with the drawing for the client for this 1.4462 duplex stainless steel casting product.
