S460M Equivalent JIS Grade Steel Plate Supplier

Gangsteel – China's Leading Mill-Direct Supplier & Exporter of S460M Equivalent JIS Grade Steel Plates

Gangsteel is the professional supplier you can trust for S460M equivalent JIS grade steel plates, with the largest permanent stock in Asia – over 5,000 tons always ready in thickness 6–200 mm, width 1500–4200 mm, length up to 18 meters. All plates are genuine TMCP (thermomechanical controlled process) produced by top mills with full European approvals and third-party inspection (DNV-GL, ABS, LR, BV, CCS, KR, TÜV, SGS).

S460M is the high-strength grade in the en 10025 4 High Strength Structural Steel family, offering 460 MPa minimum yield strength and ≥40 J impact toughness at –20 °C. It is the direct TMCP alternative to normalized S460N (EN 10025-3) and the sister grade to the low-temperature bestseller S460ML (–50 °C).

We also stock the complete EN 10025-4 series, including the popular low-temperature grade en 10025 4 s460ml steel plate and the widely used en 10025 4 s355ml steel plate, as well as the standard-temperature en 10025 4 s355m steel plate.

 

What is S460M Equivalent JIS Grade Steel Plate?

S460M equivalent JIS grade refers to JIS G 3106 SM570, 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 longitudinally. 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).

TMCP's fine grains (ASTM 8-10) and low CEV ≤0.48 provide superior weldability (no preheat to 80 mm) and isotropy versus normalized or QT alternatives. JIS SM570 equivalents S460M with Rm 570-720 MPa and similar CEV, but no mandatory low-temp impact (optional testing). Common for Japanese-EU projects, where Gangsteel supplies dual EN/JIS certified plates.

Gangsteel supplies S460M with dual EN/JIS certification, ideal for hybrid specs. For chemical basis, S460M Chemical Composition EN 10025-4 Supplier; mechanical, S460M Mechanical Properties EN 10025-4 Plate Supplier.

FAQ – Detailed Answers

Q1: What is the JIS equivalent for S460M?

A: JIS G 3106 SM570 is the closest equivalent with Rm 570 MPa and similar CEV, but no mandatory low-temp impact. S460M TMCP finer grain for better HAZ.

Q2: Can I use SM570 instead of S460M?

A: Yes for general structural, but S460M required for –20 °C impact or European certification. Gangsteel supplies dual EN/JIS plates.

Q3: Price difference between S460M and SM570?

A: S460M 50–100 USD/ton higher than SM570 due to European certs and TMCP properties.

Q4: Do you have dual-certified plates?

A: Yes – EN 10025-4 S460M + JIS G 3106 SM570 is common from our stock.

Q5: Z35 availability for both?

A: Yes – large stock of S460M + Z35 and SM570 + Z35 ready.

Q6: Delivery time to Japan or Europe?

A: Stock material 3–7 days worldwide.

Q7: Can you supply triple-certified plates?

A: Yes – EN 10025-4 S460M + JIS SM570 + GB/T 1591 Q460C is possible by agreement.
