[MW:19400] Duplex Stainless Steel: Metallurgy, engineering codes & welding practices

Congratulations Mr Pradip Goswami for the article in current issue of SSW

Duplex Stainless Steels (DSS) are extremely high grade engineering alloys combining good corrosion resistance with high strength and ease of fabrication. These steels are frequently used in the oil and gas industries both in upstream and downstream applications for assemblies such as pipe work systems, manifolds and risers. Furthermore, these are used in the petrochemical industry in the form of pipelines and pressure vessels. These steels are designed to provide better corrosion resistance, particularly chloride stress corrosion and chloride pitting corrosion, in addition to having a higher strength than standard austenitic stainless steels such as Type 304 or 316, enabling thinner sections to be used and providing significant cost benefits.
