Working with 1.4373 Cold Drawn
Is 1.4373 easy to machine?
Gummy and strongly work-hardening — use rigid setups, sharp positive-rake carbide, heavy positive feed to cut under the hardened layer, and flood coolant; roughly 40 % of 1212 speed.
Can 1.4373 be welded?
Weldable by GTAW/GMAW/resistance methods with 308L or 309L filler; keep heat input low and interpass below ~150 °C, as the higher carbon and Mn make sensitization and hot cracking more likely than in 304.
Can 1.4373 be formed, bent or molded?
Deep drawable but with a high work-hardening rate — expect 30–50 % more press force than 304 and plan interstage anneals for severe draws; springback is substantial.
What surface finishes work on 1.4373?
Takes a bright mechanical or electropolished finish and PVD coating well; passivate after machining/welding and avoid carbon-steel contamination, since the lower PREN makes rust staining more likely outdoors.

What is 1.4373 Cold Drawn used for?
1.4373 Cold Drawn is typically used for kitchen equipment, industrial fasteners, furniture tubing and appliance panels. In short: low-nickel 304 substitute; cost-stable 2xx workhorse; formable but stain-prone.
What is the yield strength of 1.4373 Cold Drawn?
1.4373 Cold Drawn has a typical yield strength of 600 MPa (87 ksi) and a tensile strength of 850 MPa (123 ksi) — stronger than 86% of stainless steel grades. Strength varies by condition: see the 9 listed tempers.
Is 1.4373 Cold Drawn easy to machine?
Not especially — machinability is rated fair (44/100, better than 81% of stainless steel grades). Gummy and strongly work-hardening — use rigid setups, sharp positive-rake carbide, heavy positive feed to cut under the hardened layer, and flood coolant; roughly 40 % of 1212 speed.
Can 1.4373 Cold Drawn be welded?
Yes — weldability is rated good (60/100). Weldable by GTAW/GMAW/resistance methods with 308L or 309L filler; keep heat input low and interpass below ~150 °C, as the higher carbon and Mn make sensitization and hot cracking more likely than in 304.
What surface finishes work on 1.4373 Cold Drawn?
