2304 1.4362 Duplex Stainless Steel I Beam H Beam IPE HEA HEB Structural Section

High Strength, Corrosion Resistance & Flexible Manufacturing — Building the Next Generation of High-Performance Structural SolutionsIn sectors such as long-span bridges, offshore engineering, chemical facilities, transportation hubs, and high-end architecture, structural materials are facing increasingly demanding requirements. They must provide excellent load-bearing capacity and corrosion resistance while also addressing lightweight design, reduced maintenance costs, design flexibility, and whole-life-cycle performance.
煌港特鋼有限公司 (Peak Kong Special Steel) focuses on the high-precision manufacturing of 2304 / 1.4362 duplex stainless steel H-beams, I-beams, and special structural profiles, supported by proprietary high-power laser hybrid welding technology and intelligent flexible production lines.
We provide engineering designers, steel structure contractors, and large industrial projects with high-performance, traceable, and cost-effective specialty steel solutions.

Duplex Stainless Steel for Enhanced Structural Strength and Durability2304 / 1.4362 is an economical duplex stainless steel that combines the advantages of both ferritic and austenitic phases. Compared with conventional austenitic stainless steels, it generally provides higher yield strength. When verified against applicable design codes and engineering requirements, it can help reduce component cross-sections and overall structural weight.
Key Material AdvantagesHigher Yield Strength:
The minimum yield strength can reach approximately 400 MPa. Actual values shall be confirmed according to product thickness, applicable standard, and supply condition.
Good Corrosion Resistance:
Suitable for humid, coastal, and various corrosive industrial environments.
Improved Resistance to Stress Corrosion Cracking:
Compared with certain conventional austenitic stainless steels, it offers enhanced potential resistance to cracking under chloride-containing and high-stress conditions.
Balanced Strength and Toughness:
Combines strength, ductility, and toughness to support demanding structural applications.
Optimized Life-Cycle Cost:
Potentially reduces coating, corrosion-protection, and periodic maintenance requirements, helping lower long-term operating costs.
Under the same load-bearing requirements, designers can investigate section optimization, component thickness reduction, and structural weight reduction based on material strength and cross-sectional efficiency. This may help reduce foundation loads, transportation costs, and lifting requirements.
Actual weight-reduction ratios must be determined through professional engineering calculations considering structural loading, stability, fatigue, connections, fire protection, and other applicable design conditions.

Laser Hybrid Welding — Breaking Through Conventional Structural Profile Manufacturing LimitationsConventional hot-rolled structural profiles are often constrained by rolling-mill tooling, minimum order quantities, and production lead times. For small-batch, special-dimension, or non-standard cross-section projects, this can result in high tooling costs, longer delivery times, and limited design flexibility.
煌港特鋼 adopts laser hybrid welding technology, combining the high energy density of a laser beam with a stable hybrid heat source to precisely control weld penetration, heat input, and weld formation.
For applicable plate thicknesses and qualified process conditions, the technology can achieve full-penetration welding in approximately the 30–50 mm thickness range, while effectively reducing welding distortion and the size of the heat-affected zone.
This technology is particularly suitable for duplex stainless steel because welding duplex grades requires careful control of heat input, cooling rate, and post-weld microstructure.
Through welding procedure qualification, filler-metal matching, and optimization of welding parameters, the phase balance, strength, toughness, and corrosion resistance of welded joints can be better controlled.
It should be emphasized that the actual duplex phase balance and joint performance after welding shall be determined based on the actual product, qualified welding procedure, and inspection results, and confirmed by appropriately qualified engineering and inspection personnel.

International Standards and a Fully Traceable Quality System煌港特鋼 establishes a comprehensive quality-control system covering raw materials, manufacturing, welding procedures, dimensional inspection, and non-destructive testing, in accordance with the quality-management requirements of international engineering projects.
Depending on project requirements, applicable references and standards may include:
EN 10088 Series — Stainless steel material standards
EN 15614-11 — Welding procedure qualification for laser welding
EN 15614-14 — Welding procedure qualification for laser-arc hybrid welding
ASTM A484 — General requirements for stainless steel products
Relevant EN, ASTM, JIS, and BS standards for structural profiles and structural design
Third-party audit and inspection requirements from organizations such as SGS, TÜV, and DNV

Large structural profiles can be inspected according to project specifications through ultrasonic testing, penetrant testing, dimensional inspection, weld inspection, and material performance verification.
Products can be supplied with Material Test Certificates, inspection reports, NDT records, and production-batch information, enabling digital quality traceability from raw material through finished-product delivery.
