2507 1.4410 Super Duplex Stainless Steel Channel Steel UPE UPN C Channel Structural Section

2507 / 1.4410 Super Duplex Stainless Steel ChannelsBreaking Hot-Rolling Limitations • Laser Hybrid Welding for 30 mm Full-Penetration Non-Standard Custom Profiles
Peak Kong Special Steel applies innovative Laser + CMT hybrid welding technology and proprietary automated flexible production lines to achieve high-volume, high-precision manufacturing of 2507 / 1.4410 Super Duplex Stainless Steel channels.
Our innovative laser hybrid welding process replaces conventional hot-rolling processes and successfully overcomes the industry challenges associated with forming large-size, thick-wall duplex stainless steel profiles by conventional hot rolling. We provide 100% full-penetration welding for weld thicknesses up to 30 mm. This ensures structural strength comparable to integral formed sections while providing exceptional flexibility for small-batch, multi-size, highly customized and non-standard profile requirements that conventional hot rolling cannot efficiently accommodate.
Our products are manufactured to meet stringent international requirements, including EN, ASTM, JIS and BS standards, providing reliable structural support for heavy-duty and highly corrosive engineering applications worldwide.
Core Technical Capabilities & Processing AdvantagesComprehensive International Standards Compliance:
Materials and manufacturing are strictly aligned with EN 10088-5 for stainless steel structural sections, ASTM A484 / A484M for general requirements for stainless steel products, and EN 10279 for dimensions and tolerances of hot-rolled steel channels.
Eurocode 3 Compatibility:
The product range is fully compatible with Eurocode 3 Part 1-4 (EN 1993-1-4), the supplementary design standard for stainless steel structures, providing reliable mechanical calculation and structural design references for engineering consultants worldwide.
Certified Welding Procedures:
Welding Procedure Qualification Records (WPQR) are qualified in accordance with EN ISO 15614-11 for laser welding and EN ISO 15614-14 for hybrid welding. Our welding processes and production capabilities have undergone audits and certification by internationally recognized organizations including SGS, TÜV and DNV, supporting demanding extreme-service and high-load structural applications.
100% Quality Traceability & International Market Access:
Each shipment can be supplied with official inspection reports and non-destructive testing documentation, together with complete Material Test Certificates (MTC 3.1 / 3.2). CE and UKCA requirements can also be supported, helping ensure smooth participation in international engineering projects and tenders.

Key Advantages of 2507 / 1.4410 Super Duplex Stainless Steel ChannelsBeyond Conventional Hot-Rolling Limitations — 30 mm Full Penetration:
Our advanced manufacturing process addresses the technical challenges of producing thick-wall Super Duplex stainless steel channels through conventional hot rolling, enabling 100% full-penetration welded structures up to 30 mm in weld thickness.
Controlled Heat Input & Metallurgical Stability:
The high-energy density of laser hybrid welding is combined with the low heat input characteristics of CMT. This enables precise control of the thermal cycle and weld microstructure, helping suppress the precipitation of detrimental intermetallic phases such as sigma phase while maintaining high weld integrity, strength and low-temperature toughness.
High Strength & Structural Lightweighting:
With a yield strength of approximately 550 MPa or higher, 2507 / 1.4410 can provide substantially higher strength than conventional 316L stainless steel. Within the Eurocode 3 design framework, the higher material strength can enable optimized and potentially thinner structural sections, reducing structural dead weight and helping lower material consumption in large-scale infrastructure projects.
Exceptional Corrosion Resistance for Long-Service Applications:
With a carefully balanced chromium, molybdenum and nitrogen alloying system and a typical PREN ≥ 40, 2507 / 1.4410 provides excellent resistance to pitting, crevice corrosion and chloride-containing environments. It is particularly suitable for coastal and marine exposure, direct seawater contact and aggressive chemical environments, while offering strong resistance to stress corrosion cracking (SCC). Actual service life depends on design, environment, fabrication and maintenance conditions; properly engineered systems can target decades of service with reduced maintenance requirements.
