Crafted in line with international standards, our rectangular bars are celebrated for their remarkable strength, excellent weldability, and long-lasting service life. At Kanish Metals, we’re dedicated to fulfilling the varied needs of industries such as oil & gas, construction, marine, and chemical processing, ensuring timely deliveries and dependable products.
**Duplex Steel Rectangular Bars** are crafted from duplex stainless steel grades like **S31803 and S32205**, which include about **22% chromium, 5–6% nickel, 3% molybdenum**, and **0.14–0.20% nitrogen**. These bars feature a unique dual-phase microstructure of ferrite and austenite, which enhances their strength and resistance to corrosion. They boast a **tensile strength of 620–880 MPa**, **yield strength of at least 450 MPa**, and an **elongation of around 25%**. With their superior resistance to stress corrosion cracking, pitting, and crevice corrosion, duplex rectangular bars are perfect for use in aggressive and high-stress environments.
