15Cr-8Ni Austenitic Stainless (var. 2)

metal

A precipitation-hardened austenitic stainless steel combining chromium (15.4%), nickel (8%), and aluminum (2.45%) to achieve high strength through age-hardening mechanisms while retaining austenitic phase stability. This variant represents a specialty engineered stainless designed to balance corrosion resistance with elevated strength, positioning it between conventional austenitic grades and martensitic/precipitation-hardened stainless families. Industries deploying this alloy seek high-strength corrosion-resistant components where standard 300-series austenitic grades are insufficient, yet full martensitic hardening behavior is undesirable; applications include aerospace fasteners, pressure vessels, springs, and chemical equipment operating in moderately corrosive environments at elevated temperatures.

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.
