EN 10025-4 S275M is a thermomechanically rolled (TMCP) weldable fine-grain structural steel, where "S" denotes structural use, "275" nominal yield 275 MPa (≤16 mm transverse), "M" TMCP delivery (900-1100 °C rolling + 20-40 °C/s cooling). TMCP refines ferrite-bainite with microalloying (Nb ≤0.05%, V ≤0.10%, Ti ≤0.05%) for ASTM 8-10 grains, ensuring elongation ≥24% and KIc >130 MPa√m at –20 °C.
CEV ≤0.38 enables preheat-free welding to 100 mm, density 7.85 g/cm³ for mass calc, hardness 130-170 HBW for machining. Vs S235JR (EN 10025-2), S275M offers 15% higher yield for 10% thinner sections under Eurocode 3, with partial factor γM0 = 1.0. Gangsteel verifies with tensile testing (EN ISO 6892-1).

Q2: S275M weld preheat?
A: No; CEV ≤0.38 to 100 mm H4 electrodes. Bulk: 75–120 °C via EN 1011. CET per batch PQR.
Q3: S275M for vessels?
A: Yes—PED I low EN 10028. t-scale; VI EN 10228.
Q4: S275M vs S355M cost?
A: 50-80 USD/ton premium for TMCP, offset 15% thinness. FOB: ~680–780 USD/ton (25 mm).
Q5: Z for S275M?
A: Z25 base; Z35 for pulls. EN 10164 Cl.1.
Q6: S275M = A572 Gr.42?
A: Yield close (275 vs 290 MPa); S275M finer grain. AISC ok w/ impact.
Q7: S275M custom time?
A: Stock: 1–3 days. Fab: 2–4 days. Roll: 3–4 weeks; rush <4 MT.
