What is 1.4597?
1.4597 (X8CrMnCuN17-8-3, S20100/201) is a low-nickel austenitic stainless in which manganese, copper and nitrogen replace part of the nickel used in 300-series grades. Engineers specify it for cost-driven cold-formed and deep-drawn work in sheet, strip, cold-rolled coil and wire, where the annealed condition gives about 340 MPa yield, 720 MPa tensile, 50 % elongation and 195 HB. Chloride corrosion resistance is clearly below 304, so avoid marine, de-iced or chemically aggressive service; 304/1.4301 is the direct step up. 1.4597 has a density of 7.8 g/cm³ (0.282 lb/in³), heavier than 50% of stainless steel grades. It melts at 1,400°C (2,552 °F). 1.4597 has a yield strength of 340 MPa (49.3 ksi) and a tensile strength of 720 MPa (104 ksi) — weaker than 55% of stainless steel grades. Elongation at break is 50% and the elastic modulus is 197 GPa (28.6 Msi).

Working with 1.4597
Is 1.4597 easy to machine?
Work-hardens fast — use rigid setups, sharp positive-rake carbide, heavy constant feed, low-to-moderate speed and flood coolant; avoid dwelling or rubbing.
Can 1.4597 be welded?
Weldable by GTAW/GMAW/resistance methods with 308L or 307 filler; keep heat input and interpass temperature low to limit sensitisation and hot cracking from Cu/Mn.
Can 1.4597 be formed, bent or molded?
Excellent deep-drawing and cold-heading behaviour for a 200-series grade thanks to the copper addition; allow extra springback versus 304 and interstage anneal for severe draws.

What surface finishes work on 1.4597?
Takes No.4 brushed, BA and mirror polishes well; passivate after machining/welding and consider PVD or lacquer for decorative outdoor use since chloride resistance is limited.

1.4597 — frequently asked
What is 1.4597 used for?
1.4597 is typically used for appliance trim, kitchenware, structural cladding and cost-sensitive fabrications. In short: low-nickel 304 substitute; strong deep-drawing 200-series; cost-driven sheet stainless.
What is the yield strength of 1.4597?
1.4597 has a typical yield strength of 340 MPa (49.3 ksi) and a tensile strength of 720 MPa (104 ksi) — weaker than 55% of stainless steel grades. Strength varies by condition: see the 8 listed tempers.
Is 1.4597 easy to machine?
Not especially — machinability is rated fair (38/100, better than 63% of stainless steel grades). Work-hardens fast — use rigid setups, sharp positive-rake carbide, heavy constant feed, low-to-moderate speed and flood coolant; avoid dwelling or rubbing.
Can 1.4597 be welded?
Yes — weldability is rated good (65/100). Weldable by GTAW/GMAW/resistance methods with 308L or 307 filler; keep heat input and interpass temperature low to limit sensitisation and hot cracking from Cu/Mn.
What surface finishes work on 1.4597?
