16Cr-4Ni Duplex Stainless
metal16Cr-4Ni is a duplex stainless steel combining austenitic and ferritic microstructures, engineered for high strength with moderate corrosion resistance through its chromium and nickel balance. The alloy is used in structural and mechanical applications where a blend of strength and workability is required, particularly in moderately corrosive environments where full austenitic stainless steels may be overspecified. Its duplex phase balance offers improved resistance to stress-corrosion cracking compared to single-phase austenitic grades, making it a practical choice for cost-sensitive applications in chemical processing, pressure vessels, and marine infrastructure.

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.
