Stainless Steel grades
4 grades
Browse 4 stainless steel grades with international equivalents. Austenitic, ferritic, martensitic and duplex stainless grades across EN, ASTM, JIS, GB and more standards.
Duplex 2205
1.4462The most widely used duplex (austenitic-ferritic) stainless steel. Balanced 50/50 microstructure provides twice the yield strength of 304/316L with superior chloride and stress corrosion resistance. Used in oil & gas, chemical processing, marine, and pulp & paper industries.
Lean Duplex 2101 / X2CrMnNiN21-5-1
1.4162Lean duplex stainless steel with minimal Ni and Mo — the most cost-effective duplex grade. Uses Mn and N instead of expensive Ni for austenite stability. Double the yield strength of 304 (450 MPa vs 190 MPa). Used as a direct replacement for 304/316L where higher strength or better SCC resistance is needed.
Lean Duplex 2304
1.4362Lean duplex stainless steel with low Mo content. More economical than 2205 with better corrosion resistance than 304/316L. Developed for construction, water treatment, and storage tanks where full duplex properties are not required.
Super Duplex 2507
1.4410Super duplex stainless steel with PREN >40. Superior corrosion resistance to standard 2205 duplex, especially in chloride and H₂S environments. Used for subsea pipelines, offshore platform components, desalination plants, and chemical processing equipment.
