Duplex Steel UNS S31803 Pipes & Tubes

 

JMU Stainless Alloys Pvt. Ltd. is one of the known stockist rs and stockists of Duplex Steel S31803 Pipes and Tubes , which at temperatures above 300 Degree C, the brittle micro-constituents of this grade undergo precipitation, and at temperatures below -50 Degree C the micro-constituents undergo ductile-to-brittle transition; hence this grade of stainless steel is not suitable for use at these temperatures.

Duplex Steel S31803 Tubes offered by JMU Stainless Alloys Pvt. Ltd. is a stainless steel whose design enables combining improved resistance to pitting, high strength, stress corrosion, crevice corrosion and cracking. High temperature strength is similar to Type 430 in the range of 950 Degree C – 1150 Degree C, but the steel shows rapid increase in the strength below 900 Degree C. UNS S31803 Duplex Steel Pipes is widely used in oil & gas, hydro power, pressure vessels, pulp & paper, structural components and chemical tankers. The structure of this steel offered by JMU Stainless Alloys Pvt. Ltd. consists of austenite pools surrounded by a continuous ferrite phase.

UNS S31803 Duplex Steel Tubes is generally supplied in the annealed condition giving yield strengths in excess of 65 KSI (450Mpa). It is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades. JMU Stainless Alloys Pvt. Ltd. also offer these Duplex S31803 Tubes in different sizes, shapes and designs as per clients’ specifications at reasonable price.
