15Cr-1Ni Duplex Stainless (var. 2)

metal

This is a duplex stainless steel with elevated cobalt (~13.4%) and carbon (~0.75%) content, combining a ferritic-austenitic microstructure with strengthening phases that distinguish it from conventional duplex grades. The high cobalt and carbon levels suggest this variant is engineered for elevated-temperature strength and wear resistance, positioning it in specialized applications demanding superior mechanical performance beyond standard duplex stainless steels. Notable versus conventional duplex grades (2205, 2507), this composition targets demanding aerospace, power generation, or wear-critical applications where thermal fatigue and abrasion resistance outweigh corrosion pitting resistance as the primary design driver.

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.
