GB/T700 (general carbon structural steels) and GB/T1591 (low-alloy high-strength structural steels) serve different parts of the market: GB/T700 grades such as Q235 remain the cost-efficient choice for routine structural work, while GB/T1591 grades (Q345, Q390, Q420, etc.) demand a price premium because of alloying, tighter mechanical control and wider application in heavier structures and demanding […]

for 2025 we find A656 / S355J2 structural plate selling in widely different bands around the world — roughly USD 620–1,100 per metric tonne depending on origin, mill finish, thickness and delivery terms. If you need consistent weldable, normalized S355J2 plate for structural work, plan procurement around thickness, mill certification and transport lead time —

We recommend A709 / S355J0W for outdoor structural components where enhanced atmospheric corrosion resistance and reliable bridge-grade mechanical performance are required; it balances long-term maintenance savings with robust strength characteristics. Standards and designation: how A709 and S355J0W relate We treat “A709 / S355J0W” as a composite designation used by fabricators and buyers to indicate a

For 2025, standard EN10025-2 hot-rolled structural plates in grades S235, S275 and S355 traded in Europe generally within a USD ~600–720 per metric tonne band, with S355 often carrying a modest premium because of its higher minimum yield strength and broader use in heavy structural work. Market rhythm through the year showed restricted offers from

DIN 17100 ST37 and ST52 hot-rolled carbon steel plates in 2025 typically trade in a wide band — roughly USD 400 to USD 1,200 per metric ton depending on grade, thickness, heat treatment, origin, order size, and surface finish. Bulk factory lots from Chinese mills frequently sit at the lower end of that band, while

JIS G3101 SS400, SS490 and SS540 plates remain the workhorse structural steels in 2025 — they combine predictable mechanical performance with broad availability — and typical market prices in 2025 vary by region from roughly $380–$760 / tonne in China, $850–$980 / tonne in North America (hot-rolled base), and intermediate ranges in Europe, Japan and

We estimate typical market prices for ASTM A203/ASME SA-203 pressure vessel steel plate in 2025 range roughly from USD 650 to USD 1,600 per metric ton, depending on grade (A–F), nickel content, order size, origin (mill-direct vs. merchant), and inspection/certification requirements. These prices are directional — exact quotations must come from mills or authorized distributors

For 2025 the typical market price for ASTM A204 (ASME SA-204) pressure-vessel molybdenum-alloy plates ranges broadly between USD $600–$1,200 per metric ton depending on grade (A/B/C), mill origin, order size, heat treatment, and delivery terms — with most commonly quoted trade prices clustering in the $650–$900/ton band for standard Grade B normalized plates from major

For 2025 we find ASTM A285 plate remains one of the lower-cost pressure-vessel carbon steels: typical market quotes seen in mid-2025 run from roughly USD 660 per tonne in some Chinese wholesale markets up to about USD 1,500–1,800 per tonne for small-lot, higher-service or export orders; final landed cost depends heavily on grade (A/B/C), thickness,

In 2025 ASME/ASTM A387 (SA-387) pressure-vessel chromium-molybdenum alloy plates are priced widely depending on grade, class, quantity, origin and finish — typical market offers range roughly USD 500–3,200 per metric ton, with most commercial bulk quotes for Grades 5/9/11/22 clustered between USD 600–1,200/ton from Asian mills and frequently higher from Western stockists; premium heat-treated or
