Compare all 8 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
+ADefault Annealed | Pick the standard soft annealed stock (≤245 HB) for roughing and finishing on automatic lathes, with hardening and tempering done afterwards; machinability rates 70 but corrosion resistance is modest. | 400 | 700 | 14 | 215 HB | — |
Peeled / centreless ground bar | Use annealed bar that is peeled and centreless ground when shaft semi-finished parts or long slender turnings need high dimensional accuracy; strength stays at the annealed 700 MPa, 215 HB level. | 400 | 700 | 14 | 17 HRC | 3.1 % IACS |
Quenched and tempered, Rm 650–850 MPa | Choose the high-temperature-tempered condition (Rm 650–850 MPa) for medium-strength shafts and structural parts where toughness and machinability, rated 62, outweigh hardness. | 500 | 750 | 14 | 20 HRC | 3 % IACS |
Quenched and tempered, Rm 700–850 MPa | Pick this quenched and tempered delivery state (Rm 700–850 MPa) for turned valve stems and pump shafts needing both strength and wear resistance; machinability falls to 58. | 560 | 780 | 12 | 23 HRC | 3 % IACS |
Cold drawn | Choose annealed-then-cold-drawn bright bar for small turned parts needing tight tolerance and a bright surface with steadier cutting; residual stress is high and distortion risk rises. | 650 | 850 | 8 | 25 HRC | 3.1 % IACS |
Quenched and tempered, Rm 800–950 MPa | Use the high-strength quench-and-temper level (Rm 800–950 MPa, 265 HB) for fasteners and drive parts under higher loads that still require some toughness, with elongation limited to 10%. | 650 | 870 | 10 | 27 HRC | 3 % IACS |
Hardened & tempered to 43–48 HRC | Choose hardening with a temper near 300 °C to 43–48 HRC for valve plugs, wear bushings and blunt-edged tooling; wear and toughness are balanced but machinability drops to 30. | 1,200 | 1,450 | 4 | 45 HRC | — |
Hardened & low tempered to 50–54 HRC | Use quenching from 1020–1050 °C with a 180–250 °C temper to 50–54 HRC for cutlery, gauges and cutting or wear parts; this is the hardest state, with the lowest toughness and corrosion resistance. | 1,450 | 1,750 | 2 | 52 HRC | — |
What is 1.4035?
1.4035 (X46CrS13) is a resulfurised free-machining version of 1.4034, a 13 % chromium martensitic stainless steel supplied under EN 10088-3. Engineers choose it for high-volume turned parts that must reach 45–52 HRC after hardening while still cutting at roughly 70 % of AISI 1212; it is stocked mainly as bar in +A, +C, +SH and quenched-and-tempered (+QT650 to +QT800) conditions. The sulfur addition makes it effectively unweldable and lowers corrosion resistance and transverse ductility, and service is limited to about 400 °C. Where welding or better corrosion resistance is required, use 1.4021 or 1.4057 instead. 1.4035 has a density of 7.7 g/cm³ (0.278 lb/in³), lighter than 83% of stainless steel grades. It melts at 1,420°C (2,588 °F). 1.4035 has a yield strength of 400 MPa (58 ksi) and a tensile strength of 700 MPa (102 ksi) — stronger than 57% of stainless steel grades. Elongation at break is 14% and the elastic modulus is 215 GPa (31.2 Msi).

Working with 1.4035
Is 1.4035 easy to machine?
Turning behaviour is best in the annealed condition, at roughly 70 % of AISI 1212, with manganese sulfides breaking the chips; run an emulsion with extreme-pressure additives. Once hardened above 45 HRC, use CBN or ceramic inserts, or switch to grinding.
Can 1.4035 be welded?
Essentially not weldable: the combination of high carbon and sulfur promotes hot cracking and martensitic cold cracking. If a joint is unavoidable, preheat to 250–300 °C, use 309 or 410NiMo filler and temper immediately after welding; joint properties cannot be guaranteed.
Can 1.4035 be formed, bent or molded?
Cold formability is poor and limited to minor straightening and knurling. Hot work between 1100 °C and 850 °C, then cool slowly and anneal at 750–800 °C with furnace cooling.

What surface finishes work on 1.4035?
After quenching and tempering, pickle and passivate per ASTM A967 to restore the passive film. Sulfide inclusions leave pits in mirror-polished surfaces; electropolishing, PVD or electroless nickel improve both appearance and corrosion resistance.
