Working with S700MC TMCP
Is S700MC easy to machine?
Machines like a tough 250 HB HSLA steel — use coated carbide, rigid setups, moderate speeds and positive rake; drilling and tapping need reduced feeds versus mild steel.
Can S700MC be welded?
Very good weldability with low CEV (~0.40); use low-hydrogen consumables, control heat input (typically ≤1.5–2.0 kJ/mm) and interpass temperature to limit HAZ softening — matching or slightly undermatching filler is common.
Can S700MC be formed, bent or molded?
Designed for cold forming: bend transverse to rolling direction with a punch radius of about 1.5–2.5×t, allow for springback of 5–10° and avoid sheared-edge cracking by deburring or milling edges.
What surface finishes work on S700MC?
Shot-blast or pickle to remove mill scale, then zinc-rich primer/paint or powder coat; hot-dip galvanising is possible but the bath temperature slightly reduces yield strength.
S700MC 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.

S700MC TMCP — frequently asked
What is S700MC TMCP used for?
S700MC TMCP is typically used for trailer chassis rails, mobile crane boom and outrigger parts, tipper and dump bodies, truck cross-members, lifting equipment brackets and concrete pump boom sections. In short: high-strength TMCP plate.
What is the yield strength of S700MC TMCP?
S700MC TMCP has a typical yield strength of 740 MPa (107 ksi) and a tensile strength of 810 MPa (117 ksi) — stronger than 83% of steel grades. Strength varies by condition: see the 4 listed tempers.
Is S700MC TMCP easy to machine?
Reasonably — machinability is rated fair (45/100, worse than 65% of steel grades). Machines like a tough 250 HB HSLA steel — use coated carbide, rigid setups, moderate speeds and positive rake; drilling and tapping need reduced feeds versus mild steel.
Can S700MC TMCP be welded?
Yes — weldability is rated excellent (85/100). Very good weldability with low CEV (~0.40); use low-hydrogen consumables, control heat input (typically ≤1.5–2.0 kJ/mm) and interpass temperature to limit HAZ softening — matching or slightly undermatching filler is common.
What surface finishes work on S700MC TMCP?
Shot-blast or pickle to remove mill scale, then zinc-rich primer/paint or powder coat; hot-dip galvanising is possible but the bath temperature slightly reduces yield strength.
Can S700MC TMCP be formed, bent or molded?
Designed for cold forming: bend transverse to rolling direction with a punch radius of about 1.5–2.5×t, allow for springback of 5–10° and avoid sheared-edge cracking by deburring or milling edges.
What is the maximum service temperature of S700MC TMCP?
S700MC TMCP is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between S700MC TMCP and S700MC TMCP-SR?
TMCP is the default condition — standard as-delivered hot-rolled TMCP coil/sheet/plate; the condition in which all EN 10149-2 properties are guaranteed. TMCP-SR: only for large welded frames needing dimensional stability; keep below ~580 °C and short holds, since TMCP strength is permanently lost at higher temperatures. Yield strength is 740 MPa in TMCP versus 700 MPa in TMCP-SR.
