Duplex Steel S31803 Plates

S31803 Duplex Steel Plate is composed of high-alloy stainless steel that contains 22% chromium, 3% molybdenum, and 5-6% nickel. This combination creates an excellent balance of better corrosion resistance and strength that makes it suitable for various applications, such as petrochemicals, marine environments, and food processing. Its unique chemical composition results in double-phase characteristics, allowing the precision engineering of mechanical properties while maintaining good weldability and formability - optimizing the cost/performance ratio. With higher tensile strength than regular stainless steel grades, Duplex Steel S31803 Plates offer superior performance amongst its grade category with enhanced corrosion protection from recognized industrial standards.

Duplex Steel S31803 Plate is an immensely versatile material, providing high levels of mechanical performance and ease of fabrication. It offers excellent corrosion resistance, so it is often used in various chemical and marine engineering applications for paper production. The exceedingly strong combination of yield strength, tensile strength, and stress-corrosion cracking resistance make this plate ideal for actions where these properties are paramount, such as boilers, contractors, and heat exchangers. Moreover, the impact toughness at -50°C makes Duplex Steel Plates unbeatable in cryogenic environments. Overall, the high levels of durability provided by Duplex Steel S31803 Plate render it essential for many industries worldwide.
