What is 60SiCrV7?
60SiCrV7 (1.8153, equivalent to 60Si2CrVA and AISI 9260) is a high-carbon silicon-chromium-vanadium spring steel in the EN 10083 family with strong hardenability and a high elastic limit. It is specified for heavy-duty springs and is supplied as flat bar, rod and wire in +QT, +A, +AC, +S, +H, +CH, +C and OT-VDSiCr conditions, reaching 1550 MPa yield, 1750 MPa tensile, 7 % elongation and about 480 HB (50 HRC) in the default temper. Limits are severe: 250 °C maximum service temperature, machinability score 12, formability 8, weldability 8 and corrosion resistance 12, so all shaping and joining must be done before hardening. 54SiCrV6 is the nearest lower-carbon alternative when toughness matters more than elastic limit. 60SiCrV7 has a density of 7.8 g/cm³ (0.282 lb/in³), lighter than 87% of steel grades. It melts at 1,420°C (2,588 °F). 60SiCrV7 has a yield strength of 1,550 MPa (225 ksi) and a tensile strength of 1,750 MPa (254 ksi) — stronger than 97% of steel grades. Elongation at break is 7% and the elastic modulus is 206 GPa (29.9 Msi).

Working with 60SiCrV7
Is 60SiCrV7 easy to machine?
Machine only in the +A/+AC condition (~200–240 HB) with carbide tooling and rigid setups; once quenched to 50 HRC only grinding, EDM or CBN turning are practical.
Can 60SiCrV7 be welded?
Essentially unweldable in service condition — 0.6 %C gives very high carbon equivalent; if unavoidable, preheat 300–350 °C, use low-hydrogen consumables and re-temper immediately.
Can 60SiCrV7 be formed, bent or molded?
Cold coil/bend in the spheroidized condition or use hot coiling at 850–950 °C; harden by oil quench from 850–880 °C and temper 400–480 °C, then shot peen and pre-set springs.
60SiCrV7 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.
| Element | Spec limit (wt %) | Nominal |
|---|---|---|
| CEN 10089 | 0.55 – 0.65 | 0.6 |
| Siraises elastic limit and relaxation resistance; promotes decarburization | 1.5 – 1.8 | 1.65 |

| Vgrain refinement, carbide precipitation | 0.1 – 0.2 | 0.15 |
| P | ≤ 0.03 | |
| S | ≤ 0.03 | |
| Fe | balance |
What surface finishes work on 60SiCrV7?
No natural corrosion protection: shot peen, then phosphate + oil, powder coat or Zn/Zn-Ni plate with a 190–220 °C post-plate bake to avoid hydrogen embrittlement; keep decarburized surface layer ground off.
