18Cr-6Ni Austenitic Stainless

metal

18Cr-6Ni is a precipitation-hardened austenitic stainless steel combining the corrosion resistance of the chromium-nickel austenitic family with enhanced strength through aluminum and carbon-driven strengthening mechanisms. This material targets high-strength applications where traditional 300-series austenitic stainless steels (like 304 or 316) fall short mechanically, finding use in aerospace fasteners, high-performance springs, and demanding structural components in chemical and oil & gas environments. Its aluminum content positions it between conventional austenitic and martensitic hardened stainless grades, offering a balance of corrosion resistance and yield strength that makes it valuable for weight-critical or high-load bearing applications where standard austenitic grades would require thicker sections.

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.
