Special Stainless Steel Plates, Sheets & Strips

Special stainless steel plates and sheets are specifically engineered for critical industrial applications demanding elevated mechanical strength and superior corrosion resistance beyond conventional austenitic grades. Incorporating advanced Duplex, Super Duplex, Super Austenitic, and Precipitation Hardening stainless steel alloys, our inventory is designed to resist stress corrosion cracking (SCC), localized pitting, crevice attack, and high-temperature oxidation in hostile chemical and offshore environments.

Featured Special Stainless Steel Families & Key Applications

  • Duplex & Super Duplex Plates (2205 / 2507): Deliver double the yield strength of 316L alongside high immunity to chloride stress cracking for marine, subsea, and offshore oil & gas platforms.
  • Super Austenitic Plates (254SMO / 904L): Feature high molybdenum and nitrogen additions (PREN ≥ 42 for 254SMO) for aggressive halide, sulfuric acid, and flue gas desulfurization (FGD) systems.
  • Precipitation Hardening Plates (17-4PH / UNS S17400): Combines ultra-high mechanical strength (yield strength ≥ 1170 MPa) with good corrosion resistance for high-stress aerospace and mechanical components.
  • High-Temperature Austenitic Plates (310S / 347H): Exceptional scaling resistance up to 1150°C and high creep strength for furnace linings, heat exchangers, and petrochemical reformers.
  • Quality Assurance: 100% Ultrasonic Testing (UT), PMI material verification, and full Mill Test Certification under EN 10204 3.1.
