Chemical & Environmental3

Corrosion resistance is fair (43/100), worse than 88% of stainless steel grades.

Galvanic Potential (seawater, vs SCE)-0.2 V
Corrosion ResistanceFair43/100
Chemical Resistance SummaryGood in atmospheric, fresh-water, mild organic-acid and hot-gas/exhaust environments; the Mo addition improves resistance to mild chlorides versus 430, but pitting and crevice attack occur in seawater or warm chloride solutions. Ti stabilization prevents sensitization in weld heat-affected zones. Not for reducing mineral acids (HCl, dilute H2SO4).

Sustainability4

Producing a kilogram of 1.4589-SH takes about 53 MJ of energy and emits 3.6 kg of CO₂ — less than 67% of stainless steel grades. Typical recycled content is 65%.

Working with 1.4589-SH

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.

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-SH — frequently asked

What is 1.4589-SH used for?

1.4589-SH 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-SH?

1.4589-SH has a typical yield strength of 450 MPa (65.3 ksi) and a tensile strength of 600 MPa (87 ksi) — stronger than 70% of stainless steel grades. Strength varies by condition: see the 3 listed tempers.

Is 1.4589-SH easy to machine?

Reasonably — machinability is rated fair (52/100, better than 91% 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-SH be welded?

Yes — weldability is rated good (68/100). 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-SH?

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.

Can 1.4589-SH 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.

What is the maximum service temperature of 1.4589-SH?

1.4589-SH 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 1.4589-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.
