| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
+ATDefault Solution annealed | Standard stocked condition for wire rod, wire and bar to be cold-headed or cold-extruded; maximum ductility and corrosion resistance. | 220 | 570 | 50 | 150 HB | — |
Annealed and lightly cold drawn | Choose for coil wire fed straight to multi-station headers: bright surface and straightness with almost no loss of heading ductility. | 320 | 620 | 40 | 180 HB | 2.4 % IACS |
Cold drawn to 700–850 MPa | Cold-drawn wire/bar for parts that need higher proof strength but still some upset or thread-rolling capability. | 520 | 770 | 25 | 20 HRC | 2.4 % IACS |
Cold-headed fastener, ISO 3506 property class 70 | The usual delivery class for bolts and screws cold-formed from this grade; strength comes from the heading/thread-rolling work. | 520 | 760 | 20 | 20 HRC | 2.4 % IACS |
Cold-headed fastener, ISO 3506 property class 80 | High-strength stainless fastener class from strongly drawn stock; only for small diameters where the required cold work is achievable. | 680 | 860 | 14 | 27 HRC | 2.4 % IACS |
Cold drawn to 900–1100 MPa | Heavily drawn wire for springs, clips and high-strength shafts where no further heavy cold upsetting is required. | 800 | 1,000 | 12 | 30 HRC | 2.4 % IACS |
What is 1.4650?
1.4650 (X2CrNiCu19-10) is a low-carbon, copper-bearing 19-10 austenitic stainless with a reduced work-hardening rate for cold heading, where the ≤0.03 % carbon preserves weldability and resistance to sensitization. It is supplied as CHQ wire and bar in solution-annealed (+AT), low-carbon (+LC) and cold-worked +C700/+C900 conditions and to property classes A2-70 and A2-80, with 220 MPa yield, 570 MPa tensile, 50 % elongation, 150 HB (80 HRB) and formability rated 97. Strength in the annealed state is low and machining behaves like 304L (gummy, work-hardening); use 1.4640 where weldability is not required or 1.4646 where higher strength is needed. 1.4650 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). 1.4650 has a yield strength of 220 MPa (31.9 ksi) and a tensile strength of 570 MPa (82.7 ksi) — weaker than 99% of stainless steel grades. Elongation at break is 50% and the elastic modulus is 200 GPa (29 Msi).

Working with 1.4650
Is 1.4650 easy to machine?
Machine like 304L — sharp positive tools, rigid setup, 60–120 m/min carbide, heavy flood coolant; it work-hardens and is gummy, so avoid dwelling and use free-cutting grades if turning dominates.
Can 1.4650 be welded?
Excellent with TIG/MIG/resistance welding using 308L/347 filler; no post-weld anneal needed thanks to ≤0.03 % C, keep heat input moderate to limit distortion.
Can 1.4650 be formed, bent or molded?
This is the grade's strength: low work-hardening allows multi-blow cold heading, cold extrusion and thread rolling with lower forces and better die life than 304; anneal between severe operations if reductions exceed ~60 %.

1.4650 — frequently asked
What is 1.4650 used for?
1.4650 is typically used for cold-headed fasteners, welded cold-formed components, rivets and clinch studs, cold-extruded shafts and pins, thread-rolled screws to A2-70/A2-80 and deep-drawn housings and cups. In short: weldable heading stainless; highest formability in family; no sensitization from welding.
What is the yield strength of 1.4650?
1.4650 has a typical yield strength of 220 MPa (31.9 ksi) and a tensile strength of 570 MPa (82.7 ksi) — weaker than 99% of stainless steel grades. Strength varies by condition: see the 6 listed tempers.
Is 1.4650 easy to machine?
Not especially — machinability is rated fair (40/100, better than 72% of stainless steel grades). Machine like 304L — sharp positive tools, rigid setup, 60–120 m/min carbide, heavy flood coolant; it work-hardens and is gummy, so avoid dwelling and use free-cutting grades if turning dominates.
Can 1.4650 be welded?
Yes — weldability is rated excellent (88/100). Excellent with TIG/MIG/resistance welding using 308L/347 filler; no post-weld anneal needed thanks to ≤0.03 % C, keep heat input moderate to limit distortion.

What is the maximum service temperature of 1.4650?
1.4650 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 1.4650 +AT and 1.4650 A2-80?
+AT is the default condition — standard stocked condition for wire rod, wire and bar to be cold-headed or cold-extruded; maximum ductility and corrosion resistance. A2-80: high-strength stainless fastener class from strongly drawn stock; only for small diameters where the required cold work is achievable. Yield strength is 220 MPa in +AT versus 680 MPa in A2-80.
