Difference Between Duplex And Super Duplex

Stainless Steel is classified into numerous types based on the microstructure and chemical composition of the alloy. The main types of Stainless steel include 409 Stainless Steel pipes. Duplex Stainless steel is an alloy with a dual-phase structure with properties similar to two other types of Stainless Steel viz., Austenitic and Ferritic. The Ferritic and austenitic properties and structure in Duplex SS is a proportionate 50%. Duplex Stainless Steel is further divided into three more subcategories or types. One of them happens to be “Super Duplex Stainless Steel”. This particular sub-type of Duplex SS has better corrosion resistance than Duplex Stainless steel due to its highly alloyed chemistry. Along with this, the mechanical strength is also off the charts.
