What Is a 4×8 2507 Series Stainless Steel Plate?
A 4×8 2507 series stainless steel plate refers to a Super Duplex Stainless Steel 2507 (UNS S32750) plate supplied in the standard sheet size of 4 ft × 8 ft (1219 × 2438 mm). This size is widely used in fabrication, cutting, and structural applications due to its excellent material utilization rate and compatibility with global processing equipment.
Super Duplex 2507 is engineered for extreme corrosion environments, offering a unique combination of very high strength, outstanding chloride resistance, and long service life, making it a preferred material in offshore, chemical, and marine industries.
4×8 2507 Stainless Steel Plate Price
As of January 9, 2026, the FOB China price for 4×8 ft (1219×2438 mm) UNS S32750 (2507) super duplex stainless steel plates (ASTM A240, NO.1 hot-rolled finish, 6–12 mm thick, MOQ ≥1 ton) is $10.80–$12.50/kg ($10,800–$12,500/ton), which is 2.1–2.4 times that of 316L stainless steel and 3.5–3.8 times that of 304 stainless steel, with premiums of 15–20% for 2B cold-rolled finish and 8–12% for thicknesses <5 mm or >15 mm.
Why choose 2507 super duplex stainless steel plate?
Compared to standard duplex stainless steel 2205 and austenitic stainless steels (such as 316L), 2507 stainless steel plate offers significantly higher performance in both mechanical strength and corrosion resistance, with a yield strength approximately twice that of 316L stainless steel. It is suitable for high-pressure, high-chloride, and corrosive chemical environments, allowing for reduced plate thickness, lower structural weight, and minimized long-term maintenance costs.

FAQ
1.What standards does a 4×8 2507 stainless steel plate meet?
Typically supplied according to ASTM A240 / ASME SA240, with full material test certificates (MTC). Third-party inspection reports such as PMI, SGS, or BV can be provided on request.
2.Can 4×8 2507 stainless steel plates be cut or customized?
Yes. The 4×8 sheet size is standard, but plates can be cut, laser or plasma processed, and customized according to project requirements. This reduces scrap and improves fabrication efficiency.
3.How does 2507 compare with 2205 or 316L stainless steel?
2507 (S32750): Super duplex with higher Cr, Mo, and N, superior PREN ≥ 40, ideal for extreme chloride environments.
2205: Duplex steel, good corrosion resistance, cost-effective but slightly lower PREN.
316L: Austenitic stainless steel, lower strength and lower pitting resistance compared with duplex or super duplex grades.
