Working with E460M
Is E460M easy to machine?
Machines like a tough HSLA steel at ~55 % of 1212 rates — use rigid setups, positive-rake coated carbide, moderate speeds and generous feed to break the gummy chip.
Can E460M be welded?
Very good weldability (CEV ≤0.47); use low-hydrogen consumables matching 460 MPa, control heat input (typically ≤2.5 kJ/mm) and avoid PWHT above ~580 °C to protect the TMCP microstructure.
Can E460M be formed, bent or molded?
Cold bends readily with radius ≈2–3 t transverse to rolling; hot forming above 580 °C destroys the thermomechanical strength and requires re-qualification or a normalized grade.

E460M — frequently asked
What is E460M used for?
E460M is typically used for heavy-duty machine parts, high-strength structural steelwork, welded pressure components and mobile equipment frames. In short: best-welding 460 MPa grade; low carbon equivalent TMCP; heat-sensitive microstructure.
What is the yield strength of E460M?
E460M has a typical yield strength of 500 MPa (72.5 ksi) and a tensile strength of 600 MPa (87 ksi) — stronger than 63% of steel grades. Strength varies by condition: see the 6 listed tempers.
Is E460M easy to machine?
Reasonably — machinability is rated fair (52/100, better than 52% of steel grades). Machines like a tough HSLA steel at ~55 % of 1212 rates — use rigid setups, positive-rake coated carbide, moderate speeds and generous feed to break the gummy chip.
Can E460M be welded?
Yes — weldability is rated excellent (85/100). Very good weldability (CEV ≤0.47); use low-hydrogen consumables matching 460 MPa, control heat input (typically ≤2.5 kJ/mm) and avoid PWHT above ~580 °C to protect the TMCP microstructure.

Can E460M be formed, bent or molded?
Cold bends readily with radius ≈2–3 t transverse to rolling; hot forming above 580 °C destroys the thermomechanical strength and requires re-qualification or a normalized grade.
What is the maximum service temperature of E460M?
E460M 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 E460M-M and E460M M-40-63?
M is the default condition — standard as-delivered condition for plate and sections up to 16 mm; full 460 MPa yield with 40 J at −20 °C. M-40-63: heavy TMCP plate; lowest guaranteed yield of the M grade, choose when section thickness governs. Yield strength is 500 MPa in M versus 455 MPa in M-40-63.
How much does E460M cost?
E460M is a budget-cost steel ($), cheaper than about 90% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
