Working with 1.4630 2H
Is 1.4630 easy to machine?
Soft and gummy: use sharp positive-rake carbide, rigid setups, heavy feeds and flood coolant to avoid built-up edge; rates roughly half of 12L14.
Can 1.4630 be welded?
Readily GTAW/GMAW/laser welded in thin gauges with low heat input and Ar/Ar-He shielding; Ti stabilization avoids sensitization, but keep interpass heat low to limit HAZ grain coarsening — use 430Ti/439 or austenitic 308L/309L filler.
Can 1.4630 be formed, bent or molded?
Good roll-forming, bending and moderate deep drawing with low springback and no work-hardening spike; avoid sharp bends transverse to rolling in heavy gauge and preheat to ~100 °C for severe cold bends.
What surface finishes work on 1.4630?
Passivate or electropolish after pickling; No.4 brushed and bright annealed finishes take well, and it accepts painting/enamel after light abrasion — do not anodize.

What is 1.4630 2H used for?
1.4630 2H is typically used for exhaust components, heat exchanger parts and domestic appliances. In short: low-cost stabilized ferritic; weld-friendly in thin gauge; nickel-free 850 °C grade.
What is the yield strength of 1.4630 2H?
1.4630 2H has a typical yield strength of 460 MPa (66.7 ksi) and a tensile strength of 560 MPa (81.2 ksi) — stronger than 73% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is 1.4630 2H easy to machine?
Reasonably — machinability is rated good (60/100, better than 98% of stainless steel grades). Soft and gummy: use sharp positive-rake carbide, rigid setups, heavy feeds and flood coolant to avoid built-up edge; rates roughly half of 12L14.
Can 1.4630 2H be welded?
Yes — weldability is rated very good (75/100). Readily GTAW/GMAW/laser welded in thin gauges with low heat input and Ar/Ar-He shielding; Ti stabilization avoids sensitization, but keep interpass heat low to limit HAZ grain coarsening — use 430Ti/439 or austenitic 308L/309L filler.
What surface finishes work on 1.4630 2H?
Passivate or electropolish after pickling; No.4 brushed and bright annealed finishes take well, and it accepts painting/enamel after light abrasion — do not anodize.
Can 1.4630 2H be formed, bent or molded?
Good roll-forming, bending and moderate deep drawing with low springback and no work-hardening spike; avoid sharp bends transverse to rolling in heavy gauge and preheat to ~100 °C for severe cold bends.
What is the maximum service temperature of 1.4630 2H?
1.4630 2H is rated for continuous use to about 400°C (752 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4630-A and 1.4630-CD?
A is the default condition — standard stocked condition for sheet and strip that will be formed, welded or roll-formed. CD: bar and wire condition for turned fittings, shafts of light duty and cold-headed parts. Yield strength is 300 MPa in A versus 500 MPa in CD.
