What is 1.4630?
1.4630 (X2CrSiTi15) is a titanium-stabilized 15% Cr ferritic stainless with a silicon addition that raises oxidation resistance and keeps welds free of sensitization in mildly corrosive service. It is used where a nickel-free, low-cost stainless must be welded in thin gauge and see moderate heat, and is stocked as annealed and bright-annealed sheet (A, 2R), hot-rolled 1D, cold-drawn and hard-temper bar or strip (CD, 2H) and as-welded tube (AW). Typical values are 300 MPa yield, 460 MPa tensile, 28% elongation, 155 HB (82 HRB) and service to 850 °C. At 15% Cr, corrosion resistance and formability (score 70) sit below 18% Cr grades; 1.4510 (439) is the nearest alternative. 1.4630 has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 83% of stainless steel grades. It melts at 1,450°C (2,642 °F). 1.4630 has a yield strength of 300 MPa (43.5 ksi) and a tensile strength of 460 MPa (66.7 ksi) — weaker than 68% of stainless steel grades. Elongation at break is 28% and the elastic modulus is 220 GPa (31.9 Msi).

Working with 1.4630
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.
1.4630 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

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 used for?
1.4630 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?
1.4630 has a typical yield strength of 300 MPa (43.5 ksi) and a tensile strength of 460 MPa (66.7 ksi) — weaker than 68% of stainless steel grades. Strength varies by condition: see the 4 listed tempers.
Is 1.4630 easy to machine?
Reasonably — machinability is rated good (55/100, better than 94% 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 be welded?
Yes — weldability is rated very good (80/100). 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?
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 be formed, bent or molded?

What is the maximum service temperature of 1.4630?
1.4630 is rated for continuous use to about 850°C (1,562 °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.
How much does 1.4630 cost?
1.4630 is a standard-cost stainless steel ($$), cheaper than about 71% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
