What is 1.4589?
1.4589 (X5CrNiMoTi15-2) is a titanium-stabilized 15% Cr ferritic stainless steel with small nickel and molybdenum additions that raise toughness and weld-zone ductility (weldability score 72). It is used for welded exhaust and structural hardware in 1D, 2B and 2R sheet, plate and cold-drawn bar, with typical annealed values of 300 MPa yield, 490 MPa tensile, 22% elongation and 170 HB and service to 700 °C. Corrosion resistance is modest (score 45) and formability (score 60) is below austenitic 304, while machinability rates only 48; consider 1.4509 (441) for deeper draws or 304 for wet chloride exposure. 1.4589 has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 83% of stainless steel grades. It melts at 1,420°C (2,588 °F). 1.4589 has a yield strength of 300 MPa (43.5 ksi) and a tensile strength of 490 MPa (71.1 ksi) — weaker than 68% of stainless steel grades. Elongation at break is 22% and the elastic modulus is 220 GPa (31.9 Msi).

Working with 1.4589
Is 1.4589 easy to machine?
Machines like 430/434 — rigid setups, sharp positive-rake carbide, moderate speeds with generous coolant to avoid work hardening and built-up edge; cold-drawn bar chips more cleanly than annealed.
Can 1.4589 be welded?
Readily TIG/MIG/plasma welded without post-weld annealing thanks to Ti stabilization; keep heat input low to limit HAZ grain coarsening and use a 316L/309L or matching-Ti filler for ductile joints.
Can 1.4589 be formed, bent or molded?
Cold bends and moderate draws are fine with generous bend radii (≈1–1.5 t) and springback allowance; deep drawing and stretch forming are more limited than with austenitic 304.
1.4589 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 1.4589?
Cannot be anodized — passivate per ASTM A967 or electropolish; takes a good ground/brushed or mirror finish, and shot-blasted or painted surfaces adhere well after degreasing.

1.4589 — frequently asked
What is 1.4589 used for?
1.4589 is typically used for exhaust systems, heat exchanger parts, structural fittings and automotive components. In short: ni-Mo modified ferritic; weldable exhaust grade; tougher than plain 430.
What is the yield strength of 1.4589?
1.4589 has a typical yield strength of 300 MPa (43.5 ksi) and a tensile strength of 490 MPa (71.1 ksi) — weaker than 68% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.
Is 1.4589 easy to machine?
Reasonably — machinability is rated fair (48/100, better than 88% of stainless steel grades). Machines like 430/434 — rigid setups, sharp positive-rake carbide, moderate speeds with generous coolant to avoid work hardening and built-up edge; cold-drawn bar chips more cleanly than annealed.
Can 1.4589 be welded?
Yes — weldability is rated very good (72/100). Readily TIG/MIG/plasma welded without post-weld annealing thanks to Ti stabilization; keep heat input low to limit HAZ grain coarsening and use a 316L/309L or matching-Ti filler for ductile joints.
What surface finishes work on 1.4589?

What is the maximum service temperature of 1.4589?
1.4589 is rated for continuous use to about 700°C (1,292 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4589-A and 1.4589-C?
A is the default condition — standard stocked condition for bar, sheet and fittings; best ductility, weldability and forming behaviour. C: higher strength and close dimensional tolerance for machined shafts, fittings and studs. Yield strength is 300 MPa in A versus 500 MPa in C.
How much does 1.4589 cost?
1.4589 is a premium-cost stainless steel ($$$), cheaper than about 51% 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.
