Compare all 4 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
MDefault Thermomechanically controlled processed | Standard mill condition for hot-rolled coil, strip and plate; use for all cold-forming and welded fabrication. | 495 | 580 | 22 | 175 HB | 8.5 % IACS |
M, pickled and oiled coil/strip | Same TM-rolled properties but descaled surface — choose for direct roll-forming, stamping or painting without shot blasting. | 495 | 580 | 23 | 172 HB | 8.5 % IACS |
M, thin gauge strip | Narrow/thin slit strip for roll-formed profiles; standard elongation requirement is lower than for ≥3 mm material. | 505 | 590 | 18 | 178 HB | 8.5 % IACS |
Cold-formed / roll-formed section | Work-hardened corners of roll-formed profiles show raised yield and reduced ductility — account for this in re-forming or bending. | 570 | 630 | 14 | 195 HB | 8.5 % IACS |
What is S460MC?
S460MC (Q460M equivalent) is the higher-strength member of the thermomechanically rolled micro-alloyed MC sheet family, supplied as rolled (M), pickled and oiled, thin gauge or cold formed, with 495 MPa yield, 580 MPa tensile and 22 % elongation. It is specified where sections must be lighter without giving up weldability — CEV is about 0.35–0.38 — and is stocked as hot-rolled coil, sheet and strip for cutting, punching and press braking. Formability is lower than S355MC/S420MC, so bend radii and springback allowances must increase, and the steel needs paint or zinc coating for corrosion protection. Drop to S420MC if tighter bends are needed. S460MC has a density of 7.85 g/cm³ (0.284 lb/in³), heavier than 56% of steel grades. It melts at 1,490°C (2,714 °F). S460MC has a yield strength of 495 MPa (71.8 ksi) and a tensile strength of 580 MPa (84.1 ksi) — stronger than 62% of steel grades. Elongation at break is 22% and the elastic modulus is 210 GPa (30.5 Msi).

Working with S460MC
Is S460MC easy to machine?
Machines like a tough medium-carbon steel at ~55 % of 1212; use rigid setups, sharp carbide and moderate feeds to avoid work hardening and burr formation.
Can S460MC be welded?
Excellent weldability at CEV ≈ 0.35–0.38; no preheat needed for thin gauges, use low-hydrogen consumables and limit heat input (~<1.5 kJ/mm) to protect HAZ strength.
Can S460MC be formed, bent or molded?
Cold-form only; min bend radius about 1.0×t up to 3 mm and 1.5×t above, bending transverse to rolling direction preferred; avoid hot forming above ~580 °C which erases TM strengthening.

S460MC — frequently asked
What is S460MC used for?
S460MC is typically used for mobile crane structures, truck frame rails and construction equipment. In short: strongest common MC grade; weight-saving structural sheet; tighter bend limits.
What is the yield strength of S460MC?
S460MC has a typical yield strength of 495 MPa (71.8 ksi) and a tensile strength of 580 MPa (84.1 ksi) — stronger than 62% of steel grades. Strength varies by condition: see the 4 listed tempers.
Is S460MC easy to machine?
Reasonably — machinability is rated good (55/100, better than 62% of steel grades). Machines like a tough medium-carbon steel at ~55 % of 1212; use rigid setups, sharp carbide and moderate feeds to avoid work hardening and burr formation.
Can S460MC be welded?
Yes — weldability is rated excellent (85/100). Excellent weldability at CEV ≈ 0.35–0.38; no preheat needed for thin gauges, use low-hydrogen consumables and limit heat input (~<1.5 kJ/mm) to protect HAZ strength.

What is the maximum service temperature of S460MC?
S460MC is rated for continuous use to about 350°C (662 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between S460MC-M and S460MC-CF?
M is the default condition — standard mill condition for hot-rolled coil, strip and plate; use for all cold-forming and welded fabrication. CF: work-hardened corners of roll-formed profiles show raised yield and reduced ductility — account for this in re-forming or bending. Yield strength is 495 MPa in M versus 570 MPa in CF.
