Working with 1.4662-CD
Is 1.4662 easy to machine?
Machine like 2205: rigid setups, 20–30 % lower cutting speeds than 316L, heavy positive-rake carbide, generous feed to cut through the work-hardened skin and copious coolant.
Can 1.4662 be welded?
Weldable by GTAW/GMAW/SAW with 2209 or 2307-type overalloyed filler, no preheat, heat input roughly 0.2–1.5 kJ/mm and interpass below ~250 °C to keep ferrite/austenite balance and avoid nitrides.
Can 1.4662 be formed, bent or molded?
Cold forms well but needs about twice the press force of 304 and generous springback allowance; hot work 950–1150 °C followed by full solution anneal and quench.
What surface finishes work on 1.4662?
Pickle and passivate after hot work or welding to restore the passive film; grinds, brushes and electropolishes to good finishes — do not anodize.

1.4662-CD — frequently asked
What is 1.4662-CD used for?
1.4662-CD is typically used for tanks, structural piping and industrial equipment. In short: mid-range lean duplex corrosion; higher yield than 316L; mo-lean 2205 substitute.
What is the yield strength of 1.4662-CD?
1.4662-CD has a typical yield strength of 680 MPa (98.6 ksi) and a tensile strength of 850 MPa (123 ksi) — stronger than 91% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is 1.4662-CD easy to machine?
Not especially — machinability is rated poor (28/100, worse than 79% of stainless steel grades). Machine like 2205: rigid setups, 20–30 % lower cutting speeds than 316L, heavy positive-rake carbide, generous feed to cut through the work-hardened skin and copious coolant.
Can 1.4662-CD be welded?
Yes — weldability is rated very good (70/100). Weldable by GTAW/GMAW/SAW with 2209 or 2307-type overalloyed filler, no preheat, heat input roughly 0.2–1.5 kJ/mm and interpass below ~250 °C to keep ferrite/austenite balance and avoid nitrides.
What surface finishes work on 1.4662-CD?
Pickle and passivate after hot work or welding to restore the passive film; grinds, brushes and electropolishes to good finishes — do not anodize.
Can 1.4662-CD be formed, bent or molded?
Cold forms well but needs about twice the press force of 304 and generous springback allowance; hot work 950–1150 °C followed by full solution anneal and quench.
What is the maximum service temperature of 1.4662-CD?
1.4662-CD is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
