Stainless Steel 1.4482
EN 1.4482 · UNS S82011, S32001
EN 1.4482 (X2CrMnNiMoN21-5-3) is a lean duplex stainless in which manganese replaces part of the nickel, with a molybdenum and nitrogen addition that lifts corrosion resistance above 1.4162 while keeping nickel content and alloy cost low.

What is 1.4482?
EN 1.4482 (X2CrMnNiMoN21-5-3) is a lean duplex stainless in which manganese replaces part of the nickel, with a molybdenum and nitrogen addition that lifts corrosion resistance above 1.4162 while keeping nickel content and alloy cost low. Engineers choose it for 560 MPa yield, 740 MPa tensile and 28% elongation combined with the best formability (58) and machinability (38) in the duplex family; it is available as 2B and 1D sheet and plate, bright-annealed 2R strip, quarter-hard cold-worked coil and cold-drawn bar. Corrosion resistance (score 65) is below 1.4462 and service is limited to about 250 °C, so it suits structural rather than aggressive chloride duty; move to 1.4462 when pitting resistance governs. 1.4482 has a density of 7.75 g/cm³ (0.28 lb/in³), lighter than 65% of stainless steel grades. It melts at 1,420°C (2,588 °F). 1.4482 has a yield strength of 560 MPa (81.2 ksi) and a tensile strength of 740 MPa (107 ksi) — stronger than 85% of stainless steel grades. Elongation at break is 28% and the elastic modulus is 200 GPa (29 Msi).

Working with 1.4482
Is 1.4482 easy to machine?
Machines like other duplex grades: high cutting forces and work hardening — use rigid setups, sharp coated carbide, positive rake, generous feed and flood coolant; avoid dwelling.
Can 1.4482 be welded?
Weld with GTAW/GMAW/SMAW using 2209-type or matching lean-duplex filler, no preheat, interpass below ~150 °C and controlled heat input (roughly 0.5–2.0 kJ/mm) to keep ferrite near 35–60 %; do not autogenously weld thick sections.
Can 1.4482 be formed, bent or molded?
Cold forms well but needs 1.5–2× the press force and larger bend radii/overbend than 304; hot working 1000–1150 °C followed by full solution anneal 1000–1080 °C and rapid water quench.

1.4482 — frequently asked
What is 1.4482 used for?
1.4482 is typically used for structural tanks, transportation equipment and water treatment structures. In short: lean duplex, low nickel; best-forming duplex grade; lower corrosion than 2205.
What is the yield strength of 1.4482?
1.4482 has a typical yield strength of 560 MPa (81.2 ksi) and a tensile strength of 740 MPa (107 ksi) — stronger than 85% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is 1.4482 easy to machine?
Not especially — machinability is rated fair (38/100, better than 63% of stainless steel grades). Machines like other duplex grades: high cutting forces and work hardening — use rigid setups, sharp coated carbide, positive rake, generous feed and flood coolant; avoid dwelling.
Can 1.4482 be welded?
Yes — weldability is rated very good (70/100). Weld with GTAW/GMAW/SMAW using 2209-type or matching lean-duplex filler, no preheat, interpass below ~150 °C and controlled heat input (roughly 0.5–2.0 kJ/mm) to keep ferrite near 35–60 %; do not autogenously weld thick sections.

What is the maximum service temperature of 1.4482?
1.4482 is rated for continuous use to about 250°C (482 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4482 CR-2B and 1.4482-AW?
CR-2B is the default condition — standard stocked condition for sheet and thin strip up to about 6 mm; best surface and tightest thickness tolerance. AW: reference condition for design of welded fabrications; ferrite balance and heat input govern toughness and corrosion. Yield strength is 560 MPa in CR-2B versus 520 MPa in AW.
