ASTM A789 / ASME SA789 Stainless Steel Duplex Tube for Seawater Treatment

Product Description

ASTM A789 / ASME SA789 Stainless Steel Duplex Tube for Seawater Treatment

   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 .
