Working with 1.4482-AW
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.
What surface finishes work on 1.4482?
Pickle and passivate after hot work or welding to restore the passive film; electropolishing or mechanical polishing to No.4/mirror is straightforward, but never anodize.

1.4482-AW — frequently asked
What is 1.4482-AW used for?
1.4482-AW 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-AW?
1.4482-AW has a typical yield strength of 520 MPa (75.4 ksi) and a tensile strength of 700 MPa (102 ksi) — stronger than 79% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is 1.4482-AW easy to machine?
Not especially — machinability is rated poor (33/100, worse than 57% 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-AW be welded?
Yes — weldability is rated good (65/100). 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 surface finishes work on 1.4482-AW?
Pickle and passivate after hot work or welding to restore the passive film; electropolishing or mechanical polishing to No.4/mirror is straightforward, but never anodize.
Can 1.4482-AW 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.
What is the maximum service temperature of 1.4482-AW?
1.4482-AW 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.
