What is 1.4567?
1.4567 (X3CrNiCu18-9-4, S30430) is an austenitic stainless with 3–4 % copper added to an 18/9 CrNi base to maximise cold formability. Annealed properties of 210 MPa yield, 520 MPa tensile, 55 % elongation and 150 HB, with a formability score of 95, support severe multi-station upsetting, thread rolling and deep drawing; it is normally bought as solution-annealed (+AT), low-carbon and cold-worked (+C700, +C850) wire, rod and bar for A2-70 fasteners. Machinability is low at 38 and corrosion resistance is 304-level (58) with no molybdenum, with service limited to 550 °C. For chloride exposure use the Cu-modified 316 type 1.4578. 1.4567 has a density of 7.9 g/cm³ (0.285 lb/in³), heavier than 68% of stainless steel grades. It melts at 1,400°C (2,552 °F). 1.4567 has a yield strength of 210 MPa (30.5 ksi) and a tensile strength of 520 MPa (75.4 ksi) — weaker than 100% of stainless steel grades. Elongation at break is 55% and the elastic modulus is 193 GPa (28 Msi).

Working with 1.4567
Is 1.4567 easy to machine?
Gummy and work-hardening like 304 (≈45 % of 1212): use sharp positive-rake carbide, heavy positive feed, rigid setup and flood coolant; avoid dwelling.
Can 1.4567 be welded?
Low carbon means no post-weld anneal needed for thin sections; GTAW/GMAW/resistance welding with 308L/347 filler, keep heat input low because 3–4 % Cu increases hot-cracking sensitivity.
Can 1.4567 be formed, bent or molded?
Best-in-class cold heading and multi-station upsetting: low work-hardening rate allows severe upset ratios and deep drawing with minimal interstage annealing; keep tools well lubricated.
1.4567 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.

1.4567 — frequently asked
What is 1.4567 used for?
1.4567 is typically used for cold-headed fasteners, wire forming and precision cold forming parts. In short: highest-formability austenitic; 3–4 % copper cold-heading grade; no molybdenum, 304-level corrosion.
What is the yield strength of 1.4567?
1.4567 has a typical yield strength of 210 MPa (30.5 ksi) and a tensile strength of 520 MPa (75.4 ksi) — weaker than 100% of stainless steel grades. Strength varies by condition: see the 5 listed tempers.
Is 1.4567 easy to machine?
Not especially — machinability is rated fair (38/100, better than 63% of stainless steel grades). Gummy and work-hardening like 304 (≈45 % of 1212): use sharp positive-rake carbide, heavy positive feed, rigid setup and flood coolant; avoid dwelling.
Can 1.4567 be welded?
Yes — weldability is rated good (68/100). Low carbon means no post-weld anneal needed for thin sections; GTAW/GMAW/resistance welding with 308L/347 filler, keep heat input low because 3–4 % Cu increases hot-cracking sensitivity.

What is the maximum service temperature of 1.4567?
1.4567 is rated for continuous use to about 550°C (1,022 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 1.4567 +AT and 1.4567 A2-70?
+AT is the default condition — default supply condition for cold-heading wire and deep-drawing stock: softest, most ductile, fully austenitic and non-magnetic. A2-70: finished screws/bolts cold-headed from 1.4567 wire and certified to ISO 3506 class A2-70 (700 MPa min UTS). Yield strength is 210 MPa in +AT versus 500 MPa in A2-70.
