Working with 1.4655 HR-1D
Is 1.4655 easy to machine?
Machine like 2205 but slightly easier thanks to copper: rigid setup, sharp coated carbide, low speed / high positive feed, generous coolant, avoid dwell to prevent work hardening.
Can 1.4655 be welded?
Weld with 22-9-3-L / 2209-type filler or matching consumables, low-to-moderate heat input, interpass below ~150 °C, no preheat, argon+2%N shielding helps restore austenite balance.
Can 1.4655 be formed, bent or molded?
Cold form with ~2× the press force and larger bend radii than 304 because of high yield and springback; hot form 1000–1150 °C followed by full solution anneal and water quench.
What surface finishes work on 1.4655?
Pickle and passivate after welding to remove heat tint; grinds and polishes to a bright finish, electropolishing works well; no anodizing (n/a for stainless).

1.4655 HR-1D — frequently asked
What is 1.4655 HR-1D used for?
1.4655 HR-1D is typically used for structural components, tanks and fittings. In short: easier-machining lean duplex; 2304-class corrosion, higher yield; molybdenum-free duplex economy.
What is the yield strength of 1.4655 HR-1D?
1.4655 HR-1D has a typical yield strength of 460 MPa (66.7 ksi) and a tensile strength of 680 MPa (98.6 ksi) — stronger than 73% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is 1.4655 HR-1D easy to machine?
Not especially — machinability is rated fair (44/100, better than 81% of stainless steel grades). Machine like 2205 but slightly easier thanks to copper: rigid setup, sharp coated carbide, low speed / high positive feed, generous coolant, avoid dwell to prevent work hardening.
Can 1.4655 HR-1D be welded?
Yes — weldability is rated very good (70/100). Weld with 22-9-3-L / 2209-type filler or matching consumables, low-to-moderate heat input, interpass below ~150 °C, no preheat, argon+2%N shielding helps restore austenite balance.
What surface finishes work on 1.4655 HR-1D?
Pickle and passivate after welding to remove heat tint; grinds and polishes to a bright finish, electropolishing works well; no anodizing (n/a for stainless).
Can 1.4655 HR-1D be formed, bent or molded?
Cold form with ~2× the press force and larger bend radii than 304 because of high yield and springback; hot form 1000–1150 °C followed by full solution anneal and water quench.
What is the maximum service temperature of 1.4655 HR-1D?
1.4655 HR-1D is rated for continuous use to about 280°C (536 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4655 CR-2B and 1.4655-CD?
CR-2B is the default condition — standard stocked cold-rolled sheet/strip condition for tanks, panels and press-formed parts. CD: higher strength and tight tolerance bar for fasteners, pump shafts and CNC parts; reduced ductility. Yield strength is 480 MPa in CR-2B versus 680 MPa in CD.
