18Cr-2Ni Duplex Stainless

metal

This is a duplex stainless steel with elevated cobalt and silicon content alongside chromium and nickel, representing a modified composition within the duplex family. The material is designed for high-strength applications requiring corrosion resistance, with the dual-phase microstructure (austenite + ferrite) providing a balance of strength and toughness that distinguishes it from single-phase austenitic or ferritic stainless steels. Industrial applications include chemical processing equipment, pressure vessels, and marine/offshore structures where both corrosion resistance and load-bearing capacity are critical; the elevated cobalt addition suggests potential use in specialty tooling or high-temperature service environments where enhanced hardness or wear resistance is needed alongside corrosion protection.

Quality & Standards

Industry-Specific

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
