Working with 1.4335-CD
Is 1.4335 easy to machine?
Gummy and strongly work hardening — use rigid setups, positive-rake carbide, heavy positive feed, 15–25 m/min for HSS drilling and flood coolant to avoid glazing the cut.
Can 1.4335 be welded?
Excellent weldability by GTAW/GMAW/SMAW with matching 25/20 low-carbon filler (ER310L / E310-15); keep interpass ≤150 °C and heat input low to limit hot cracking and σ-phase, no post-weld solution anneal required.
Can 1.4335 be formed, bent or molded?
Cold forms well but needs ~50% more press force than 304 due to high work-hardening; hot work 1150–1200 °C and always finish above 950 °C, then solution anneal 1050–1120 °C with rapid cooling.
What surface finishes work on 1.4335?
Pickle/passivate per ASTM A967 after hot work or welding; electropolish or mechanical polish for clean surfaces — no anodising, and avoid carbon-steel tooling contamination.

1.4335-CD — frequently asked
What is 1.4335-CD used for?
1.4335-CD is typically used for furnace components, heat exchangers, high-temperature fasteners and kiln linings. In short: highest-temperature austenitic here; no post-weld anneal needed; high-nickel, high cost.
What is the yield strength of 1.4335-CD?
1.4335-CD has a typical yield strength of 450 MPa (65.3 ksi) and a tensile strength of 700 MPa (102 ksi) — stronger than 70% of stainless steel grades. Strength varies by condition: see the 8 listed tempers.
Is 1.4335-CD easy to machine?
Not especially — machinability is rated fair (36/100, better than 57% of stainless steel grades). Gummy and strongly work hardening — use rigid setups, positive-rake carbide, heavy positive feed, 15–25 m/min for HSS drilling and flood coolant to avoid glazing the cut.
Can 1.4335-CD be welded?
Yes — weldability is rated very good (80/100). Excellent weldability by GTAW/GMAW/SMAW with matching 25/20 low-carbon filler (ER310L / E310-15); keep interpass ≤150 °C and heat input low to limit hot cracking and σ-phase, no post-weld solution anneal required.
What surface finishes work on 1.4335-CD?
Pickle/passivate per ASTM A967 after hot work or welding; electropolish or mechanical polish for clean surfaces — no anodising, and avoid carbon-steel tooling contamination.
Can 1.4335-CD be formed, bent or molded?

What is the maximum service temperature of 1.4335-CD?
1.4335-CD is rated for continuous use to about 870°C (1,598 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4335-AT and 1.4335-FH?
AT is the default condition — standard stocked condition for plate, sheet, bar and tube in high-temperature and welded service. FH: maximum-strength flat-rolled or drawn product for springs and shims; essentially no further forming. Yield strength is 270 MPa in AT versus 900 MPa in FH.
