2507 1.4410 Super Duplex Stainless Steel Plate Sheet Structural Section Bar

2507 / 1.4410 Super Duplex Stainless Steel PlatesPeak Kong Special Steel leverages a robust global supply chain and maintains substantial in-house inventory covering a complete 3 mm to 100 mm thickness range of 2507 / 1.4410 Super Duplex Stainless Steel medium and heavy plates.
We are more than a stainless steel supplier. Peak Kong Special Steel is committed to creating exceptional added value for customers through advanced surface treatment and deep-processing capabilities. Our facilities provide global customers with high-precision cutting, beveling, precision welding, non-destructive testing (NDT), and finished/semi-finished assembly through an integrated one-stop processing service.
Our products are manufactured to meet stringent international requirements, including EN, ASTM, JIS and BS standards, making 2507 / 1.4410 an ideal material solution for heavy-duty, corrosion-resistant structures operating in demanding environments.
Core Technical Capabilities & International StandardsComprehensive International Standards Coverage:
Raw materials and finished products are strictly controlled in accordance with EN 10088-2, covering technical delivery conditions for stainless steel sheet and plate, and ASTM A240 / A240M, covering chromium and chromium-nickel stainless steel plate, sheet and strip for pressure vessels and general applications. The products are also compatible with Eurocode 3 (EN 1993-1-4) and AISC 370 for stainless steel structural design.
One-Stop Precision & Deep Processing Services:
Precision Cutting:
Advanced laser cutting, plasma cutting and high-pressure waterjet cutting are available to achieve clean cutting edges, minimized heat-affected zones (HAZ) and high dimensional accuracy.
Beveling:
We provide complex X-, V- and K-groove preparation for demanding welding applications, creating optimized joint configurations for heavy-duty welding and full-penetration structural fabrication.
Welding & NDT:
Our welding procedures and capabilities undergo audits by internationally recognized organizations including SGS, TÜV and DNV. Professional NDT capabilities including UT, MT and PT provide comprehensive quality assurance for fabricated components.
100% Quality Traceability & International Market Access:
Complete official inspection documentation and Material Test Certificates (MTC 3.1 / 3.2) can be supplied with products. CE and UKCA requirements can also be supported, facilitating international tenders, major infrastructure projects and demanding pressure-equipment applications.
Green & Low-Carbon Standards:
Our plate products are managed within a low-carbon and environmentally responsible material management framework. Environmental Product Declaration (EPD) documentation and Life Cycle Assessment (LCA) carbon-footprint traceability can be provided according to project requirements. Melt and Pour traceability documentation can also be supplied to support material origin tracking and relevant EU CBAM reporting requirements.
