Working with 1.4002-CD
Is 1.4002 easy to machine?
Machines like annealed 410 but gummier — use sharp positive-rake carbide, rigid setups, 60–100 m/min, generous coolant, and avoid dwelling to prevent work-hardened skin.
Can 1.4002 be welded?
Best-in-class among 13Cr grades: Al stabilization prevents HAZ martensite so preheat is often unnecessary; use 405/430 or austenitic 309L/308L filler, low heat input, and PWHT at 730–790 °C on heavy sections to limit grain-coarsening embrittlement.
Can 1.4002 be formed, bent or molded?
Cold form in the annealed condition with generous bend radii (≥1.5t) and allowance for ~15–20 % springback; hot work at 800–1050 °C then anneal, and avoid holding at 400–550 °C (475 °C embrittlement).
What surface finishes work on 1.4002?
Passivate per ASTM A967 or pickle after welding to restore the chromium oxide film; takes brushed and mirror finishes less brightly than 430, and is commonly painted or aluminized for furnace service.

1.4002-CD — frequently asked
What is 1.4002-CD used for?
1.4002-CD is typically used for welded pressure vessels, heat exchangers and furnace components. In short: most weldable 13Cr grade; al-stabilized, no HAZ martensite; pressure-vessel ferritic stainless.
What is the yield strength of 1.4002-CD?
1.4002-CD has a typical yield strength of 420 MPa (60.9 ksi) and a tensile strength of 560 MPa (81.2 ksi) — stronger than 64% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is 1.4002-CD easy to machine?
Reasonably — machinability is rated good (60/100, better than 98% of stainless steel grades). Machines like annealed 410 but gummier — use sharp positive-rake carbide, rigid setups, 60–100 m/min, generous coolant, and avoid dwelling to prevent work-hardened skin.
Can 1.4002-CD be welded?
Yes — weldability is rated very good (72/100). Best-in-class among 13Cr grades: Al stabilization prevents HAZ martensite so preheat is often unnecessary; use 405/430 or austenitic 309L/308L filler, low heat input, and PWHT at 730–790 °C on heavy sections to limit grain-coarsening embrittlement.
What surface finishes work on 1.4002-CD?
Passivate per ASTM A967 or pickle after welding to restore the chromium oxide film; takes brushed and mirror finishes less brightly than 430, and is commonly painted or aluminized for furnace service.
Can 1.4002-CD be formed, bent or molded?
Cold form in the annealed condition with generous bend radii (≥1.5t) and allowance for ~15–20 % springback; hot work at 800–1050 °C then anneal, and avoid holding at 400–550 °C (475 °C embrittlement).
What is the maximum service temperature of 1.4002-CD?
1.4002-CD is rated for continuous use to about 450°C (842 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4002 Annealed and 1.4002-CD?
Annealed is the default condition — standard stocked condition for plate, sheet, bar and tube; maximum ductility and best weld/form behaviour. CD: bar/wire condition with tighter tolerances and higher strength; ductility and formability drop. Yield strength is 230 MPa in Annealed versus 420 MPa in CD.
