Seamless High Pressure Stainless Steel Pipe / Tubing S32304 For Chemical Storage
Super duplex stainless such as duplex is a mixed microstructure of
austenite and ferrite which has improved strength over ferritic and
austenitic steel grades. The main difference is super duplex has a
higher molybdenum and chromium content which gives the material
greater corrosion resistance.
Super duplex has the same benefits as its counterpart - it has
lower production costs when compared with similar ferritic and
austenitic grades and due to the materials increased tensile and
yield strength, in many cases this gives the purchaser the welcomed
option of purchasing smaller thicknesses without the need to
compromise on quality and performance.
