Working with 1.4362-CD
Is 1.4362 easy to machine?
Cuts like a strong austenitic but with ~2× the yield strength — use rigid setups, positive-rake coated carbide, low speed/high feed, generous coolant and avoid dwelling to prevent work hardening.
Can 1.4362 be welded?
Readily welded by GTAW/GMAW/SAW/FCAW with 2209-type over-alloyed filler (or 2304 filler with N-bearing shielding); keep heat input moderate, interpass <150 °C, no preheat, no post-weld heat treatment unless full re-solution annealing is possible.
Can 1.4362 be formed, bent or molded?
Cold forms well but needs roughly twice the press force of 304 with large springback; hot form 950–1150 °C followed by full solution anneal and quench — never finish-form in the 300–1000 °C range.
What surface finishes work on 1.4362?
Pickle and passivate after welding or hot work to restore the passive film; mechanically polishes to a satin/mirror finish, and it is not anodizable — protect against embedded carbon-steel contamination during handling.

1.4362-CD — frequently asked
What is 1.4362-CD used for?
1.4362-CD is typically used for pressure vessels, storage tanks, paper and pulp equipment and structural piping. In short: mid-range lean duplex; between 316L and 2205; good chloride SCC resistance.
What is the yield strength of 1.4362-CD?
1.4362-CD has a typical yield strength of 620 MPa (89.9 ksi) and a tensile strength of 800 MPa (116 ksi) — stronger than 88% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is 1.4362-CD easy to machine?
Not especially — machinability is rated poor (30/100, worse than 70% of stainless steel grades). Cuts like a strong austenitic but with ~2× the yield strength — use rigid setups, positive-rake coated carbide, low speed/high feed, generous coolant and avoid dwelling to prevent work hardening.
Can 1.4362-CD be welded?
Yes — weldability is rated very good (70/100). Readily welded by GTAW/GMAW/SAW/FCAW with 2209-type over-alloyed filler (or 2304 filler with N-bearing shielding); keep heat input moderate, interpass <150 °C, no preheat, no post-weld heat treatment unless full re-solution annealing is possible.
What surface finishes work on 1.4362-CD?
Pickle and passivate after welding or hot work to restore the passive film; mechanically polishes to a satin/mirror finish, and it is not anodizable — protect against embedded carbon-steel contamination during handling.
Can 1.4362-CD be formed, bent or molded?
Cold forms well but needs roughly twice the press force of 304 with large springback; hot form 950–1150 °C followed by full solution anneal and quench — never finish-form in the 300–1000 °C range.
What is the maximum service temperature of 1.4362-CD?
1.4362-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.
What is the difference between 1.4362-SA and 1.4362-CW?
SA is the default condition — standard mill-supplied condition for plate, pipe and forgings; balanced 50/50 duplex structure with best corrosion resistance and toughness. CW: use where maximum strength and stiffness-per-section are wanted in thin sections; accept reduced ductility, higher springback and residual stress. Yield strength is 460 MPa in SA versus 700 MPa in CW.
