2304 1.4362 Duplex Stainless Steel Angle Steel Equal Unequal Angle Bar Structural Section

2304 / 1.4362 Duplex Stainless Steel Equal and Unequal Angle SectionsHigh-Strength Duplex Stainless Steel · Flexible Welding as an Alternative to Hot Rolling · Structural Solutions with Exceptionally High Yield StrengthPeak Kong Special Steel utilizes innovative laser hybrid welding technology and independently developed automated flexible production lines to achieve high-volume, high-precision manufacturing of 2304 / 1.4362 duplex stainless steel equal and unequal angle sections.
With industry-leading 30 mm full-penetration welding capability, we have developed an innovative manufacturing process that provides an alternative to conventional hot rolling. This effectively addresses the challenges associated with large-size, extra-thick-wall, and small-batch customized angle sections, while meeting stringent engineering and industrial requirements under European (EN), American (ASTM), Japanese (JIS), and British (BS) standards.

2304 / 1.4362 Duplex Stainless Steel Structural Profile SpecificationsPeak Kong Special Steel’s automated flexible welding production lines can precisely manufacture the following structural profile specifications, with surface finish and geometric tolerances designed to provide significant advantages over conventional hot-rolled and standard welded products.
Equal Angles40 × 40 × 4 mm to 300 × 300 × 30 mm
Including British-standard EA, European-standard L, American-standard L series, and other applicable profile systems.
Unequal Angles50 × 30 × 4 mm to 450 × 250 × 30 mm
Including British-standard UA, European-standard L, American-standard L series, and other applicable profile systems.
Marine Angles / Inverted AnglesMarine unequal angles and inverted angles:
100 × 75 × 8 mm to 400 × 120 × 20 mm
Non-Standard Customized ProfilesCustomized dimensions can be manufactured according to customer drawings.
This flexible manufacturing approach addresses the challenges associated with hot rolling of thick-wall duplex stainless steel angles, extra-large profiles, and special leg-width ratios, allowing flexible adjustment of leg widths and wall thicknesses according to project requirements.

Core Technology and Processing Advantages30 mm Full-Penetration Flexible WeldingDue to the unique ferritic-austenitic dual-phase microstructure of duplex stainless steel, conventional heavy-plate welding can be highly sensitive to improper heat-input control, potentially resulting in weld embrittlement or phase imbalance.
Peak Kong Special Steel utilizes advanced laser hybrid welding technology to achieve 100% full-penetration welding at thicknesses of up to 30 mm.
The process features a narrow heat-affected zone (HAZ) and controlled grain growth, helping maintain mechanical performance at the right-angle corner and achieve strength compatibility with the base material, subject to qualified welding procedures and inspection requirements.
International Standards and Process QualificationOur welding team and manufacturing processes can be subject to auditing and certification requirements from internationally recognized third-party organizations such as SGS, TÜV, and DNV.
Applicable welding procedures can be qualified in accordance with:
EN 15614-11 — Laser welding procedure qualification
EN 15614-14 — Laser-arc hybrid welding procedure qualification

Profile geometry and material technical requirements can be manufactured with reference to international specifications including:
EN 10088-5
ASTM A484

100% Quality Traceability and InspectionAll extra-large structural components can be managed through 100% quality traceability and digital production records.
High-standard non-destructive testing (NDT) can include:
UT — Ultrasonic Testing
PT — Penetrant Testing

Official inspection reports and Material Test Certificates (MTCs) can be supplied with the finished products according to project requirements.
High Geometric Accuracy with No Internal Bend Radius InterferenceCompared with bent plate components, laser-hybrid-welded angle sections do not rely on mechanical bending and therefore avoid the associated internal bending and shear stress concentration.
The external geometry can be manufactured with a sharp corner or minimal radius, depending on the required design.
Excellent straightness and twist control can be achieved, providing advantages over conventional hot-rolled manufacturing for applicable customized profiles.
The absence of significant internal bend-radius interference also facilitates close-fitting connections with other structural components, including H-beams and steel plates, supporting high-precision assembly.
