Super Duplex is an austenitic-ferritic iron chromium – nickel alloy with molybdenum addition. Super duplex pipes are extremely resistant to pitting. They have an improved tensile strength and have a higher corrosion cracking resistance at moderate temperatures compared to that of normal duplex steel pipes. Super duplex steel pipe Supplier also have an impeccable resistance to erosion corrosion. The main and most pre-eminent feature of super duplex steel pipes is that it has very high mechanical strength. It is also proven that welding can be done with more ease on a super duplex steel pipe than a normal duplex pipe. From the introduction of its first-generation, super duplex steel pipes have seen a steady increase in popularity. To know more visit: http://instinox.com/steel-pipes/super-duplex-pipes/
