What is S460M Steel Equivalent GB/T 1591?

S460M steel equivalent GB/T 1591 refers to Q460C (standard temperature) or Q460D (low temperature), which closely matches S460M under EN 10025-4:2004 (2019)—a thermomechanically rolled (TMCP) weldable fine-grain structural steel with 460 MPa minimum yield strength and ≥40 J Charpy V-notch at –20 °C longitudinal.

The designation "S460M" means "S" structural, "460" nominal yield (MPa, ≤16 mm transverse), "M" TMCP delivery (900-1100 °C rolling + 20-40 °C/s cooling).

GB/T 1591 Q460C/D equivalents S460M with Rm 550-720 MPa and similar CEV, but optional low-temp impact (Q460D ≥34 J at –20 °C). Common for Chinese-EU projects, where Gangsteel supplies dual EN/GB certified plates.

Gangsteel supplies S460M equivalent to GB Q460C/D with dual certification, ideal for hybrid specs.

FAQ – Quick Answers

Q1: What is the GB equivalent for S460M?A: GB/T 1591 Q460C (standard temp) or Q460D (low temp) is the closest equivalent with yield 460 MPa and similar CEV, but optional impact testing. S460M TMCP finer grain for better HAZ.

Q2: Can I use Q460C/D instead of S460M?A: Yes for general structural, but S460M required for European certification or guaranteed –20 °C impact. Gangsteel supplies dual EN/GB plates.

Q3: Price difference between S460M and Q460C/D?A: S460M 50–100 USD/ton higher than Q460C/D due to European certs and TMCP properties.

Q4: Do you have dual-certified plates?A: Yes – EN 10025-4 S460M + GB/T 1591 Q460C/D is common from our stock.

Q5: Z35 availability for both?A: Yes – large stock of S460M + Z35 and Q460C/D + Z35 ready.

Q6: Delivery time to China or Europe?A: Stock material 3–7 days worldwide.

Q7: Can you supply triple-certified plates?A: Yes – EN 10025-4 S460M + GB/T 1591 Q460C + ASTM A913 Gr.65 is possible by agreement.
