Wai Nickel Alloys, a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, proudly offers top-quality Duplex Steel S31803 Bars. These bars are celebrated for their remarkable strength, durability, and resistance to corrosion. Designed to excel in tough industrial settings like marine, chemical, and oil and gas industries, each bar is crafted with precision and meets international quality standards. Wai Nickel Alloys guarantees that every bar boasts accurate dimensions, smooth finishes, and long-lasting reliability. The Duplex Steel S31803 Bars deliver an outstanding mix of mechanical strength and corrosion resistance, making them perfect for critical applications.
These bars feature a balanced dual-phase microstructure that includes both austenite and ferrite, which provides exceptional mechanical properties and corrosion resistance. The alloy is composed of about 22% chromium, 5–6% nickel, 3% molybdenum, and nitrogen, all of which enhance its ability to resist pitting, crevice corrosion, and chloride stress corrosion cracking. With high tensile and yield strength, excellent fatigue resistance, and good weldability, these bars are built to perform reliably under high pressure and varying temperature conditions.
