Working with S460MC M-PO
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.
What surface finishes work on S460MC?
No natural corrosion resistance — shot blast or pickle then prime/paint, hot-dip galvanize or zinc-rich coat; anodizing not applicable.

S460MC M-PO — frequently asked
What is S460MC M-PO used for?
S460MC M-PO 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 M-PO?
S460MC M-PO 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 M-PO 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 M-PO be welded?
Yes — weldability is rated excellent (86/100). 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 surface finishes work on S460MC M-PO?
No natural corrosion resistance — shot blast or pickle then prime/paint, hot-dip galvanize or zinc-rich coat; anodizing not applicable.
Can S460MC M-PO 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.
What is the maximum service temperature of S460MC M-PO?
S460MC M-PO 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.
