Champak Steel & Engg. Co is a leading manufacturer, supplier and exporter of Duplex Steel Round Bars/Rods in Mumbai, India. We supply these duplex steel bars, rods in grades such as UNS S31803, and S32205. We manufacture these bars and rods using high quality raw materials and advanced technology in accordance to national and international quality standards. Duplex Steel round bars are available in various sizes, specifications, thickness, finishes, etc. we also manufacture them in custom made specifications to fulfill the requirements of various industries. Duplex Steel UNS S31803 Round bars are referred to as stainless steel austenitic-ferrite, with equal amounts of ferrite and austenite. Since they have both austenite and ferrite microstructure which provides high tensile strength and excellent resistance to stress corrosion cracking. Such Duplex Steel Bars offer outstanding resistance to corrosion, high level of tolerance and toughness.
Duplex Steel UNS S32205 Rods possess certain silent characteristics such as high chloride stress corrosion cracking resistance, chloride cracking and ease of handling, high strength, good weldability and formability.The chromium, nitrogen and molybdenum content Duplex Steel UNS S31803 Rods are most important for chloride crevice and pitting corrosion resistance. Duplex Steel 2205 Round Bars are not generally suitable for use at temperatures above 300 degrees C as it suffers from precipitation of brittle micro-constituents, nor below -50 degrees C because of its ductile-to-brittle-transition. Duplex Steel Round Bars are hot worked in the temperature range of 954-1149 degrees C (1750-2100degrees F).
Duplex steel Rods show very good pitting and uniform corrosion resistance, high strength and high resistance to stress corrosion cracking (SCC). We supply these round bars and rods to diverse industries including seawater desalination plants, oil & gas equipment, paper & pulp industry, offshore technology, chemical & food processing, fertilizers, sugar mills & distilleries, cement industries, shipbuilding, and petrochemical industry.
We offer various test certificates along with our Duplex Steel Round Bars and Rods the test certificates include Mill Test Certificates, EN 10204 3.1/3.2, Chemical Reports, Mechanical Reports, PMI Test Reports, Visual Inspection Reports, Third Party Inspection Reports, etc.
