316Ti 1.4571 Stainless Steel Angle Steel Equal Unequal Angle Bar Structural Section

Precision Structural Solutions for High-Temperature, Corrosive and Heavy-Load EngineeringIn petrochemical, energy, marine, and high-end architectural applications, structural sections must do more than carry loads. They are often required to withstand long-term exposure to high temperatures, humidity, chlorides, acidic media, and complex welding conditions.
When standard hot-rolled sections cannot meet the requirements for special dimensions, thick-wall structures, or small-batch engineering projects, 煌港特鋼有限公司 (Peak Kong Special Steel) uses 316Ti / 1.4571 titanium-stabilized austenitic stainless steel as the material foundation, combined with our self-developed automated flexible production lines and laser hybrid welding technology, to provide one-stop manufacturing solutions for high-precision stainless steel equal and unequal angle sections.
We do more than supply standard profiles. We are committed to transforming engineering drawings, service conditions, and design requirements into high-performance structural products that are manufacturable, inspectable, and fully traceable.

1. Overcoming Conventional Hot-Rolling Limitations with Flexible Angle ManufacturingConventional hot-rolled structural sections rely heavily on fixed tooling. For extra-large dimensions, special wall thicknesses, non-standard cross-sections, and small-batch orders, this can result in high tooling costs, large minimum order quantities, and long production lead times.
Peak Kong Special Steel adopts an automated flexible manufacturing model supporting:
Standard and non-standard angle sections manufactured to drawings
Small-batch and multi-specification production
Asymmetric leg lengths and special thickness combinations
Marine angles, reverse angles, and specialized stiffening sections
Special-angle and irregular cross-section designs
Matching fabrication with H-sections, steel plates, and other structural components

By reducing dependence on fixed tooling, engineering designs can be more closely aligned with actual load conditions, installation requirements, and service environments, providing greater design flexibility for engineering design institutes, EPC contractors, equipment manufacturers, and specialized steel-structure contractors.

2. Laser Hybrid Welding: A Manufacturing Process for Thick-Wall and High-Precision Structures316Ti / 1.4571 contains titanium as a stabilizing element. During welding, heat input, interpass temperature, filler-metal selection, and shielding-gas control can all influence the microstructure and corrosion performance of the welded joint.
Peak Kong Special Steel combines the high energy density of laser welding with a low-heat-input arc welding process, enabling precision assembly and welding control for thick-wall equal and unequal angle sections.
Following the applicable welding procedure qualification and project-specific technical confirmation, we can provide full-penetration welding solutions for thicknesses up to approximately 30 mm.
Process ValueConcentrated heat input helps reduce the risk of welding distortion
Improved penetration and weld formation consistency for thick sections
Helps control welding residual stresses
Enhanced geometric accuracy in corner and joint areas
Suitable for small-batch, multi-product, and non-standard customized production
Supports subsequent non-destructive testing and quality-document management

The actual welding thickness, penetration requirements, and joint performance shall be determined according to the base-metal grade, material thickness, joint configuration, filler metal, design code, and formally qualified welding procedure.

3. 316Ti / 1.4571: A Material Choice for High-Temperature and Corrosive Environments316Ti is an austenitic stainless steel stabilized with titanium. Titanium can preferentially combine with carbon to form relatively stable titanium carbides, helping reduce susceptibility to intergranular corrosion under certain welding and high-temperature exposure conditions.
Subject to appropriate material selection and service-condition evaluation, 316Ti / 1.4571 can be applied to:
High-temperature equipment supports
Chemical and petrochemical process structures
High-humidity and chloride-containing environments
Marine and coastal engineering
Exhaust-gas treatment and environmental equipment
Durable exposed architectural structures

Actual corrosion resistance and service-temperature suitability must be evaluated in combination with chemical media, chloride concentration, temperature, stress condition, surface treatment, and design life. No absolute performance guarantee should be made based solely on the material designation.

4. Product Series and Size Range1. Equal Angle SectionsReference size range:
40 × 40 × 4 mm to 300 × 300 × 30 mm

Associated connection and stiffening components

All specifications, dimensional tolerances, straightness, twist, and surface requirements can be clearly defined in the technical agreement.

5. Quality Assurance from Material to Finished ProductFor high-end engineering projects, material quality alone is not sufficient. Complete quality management, documentation, and traceability are equally important.
Peak Kong Special Steel can establish a full-process traceability system from raw-material receipt through final delivery according to project requirements, covering:
Raw-material grade and heat-number traceability
Material chemical-composition and mechanical-property documentation
Dimensional and visual inspection
Welding procedure documentation and qualification records
Weld visual inspection
UT — Ultrasonic Testing
PT — Penetrant Testing
Third-party witnessing and inspection
EN 10204 3.1 / 3.2 Material Test Certificates

Applicable welding and product standards can be coordinated according to project requirements, including relevant EN, ASTM, JIS, BS, and other specified standards covering material, welding procedures, structural fabrication, and non-destructive testing.
The inspection, audit, and certification scope of SGS, TÜV, DNV, or other third-party organizations shall be subject to the applicable official certificates, project contracts, and Inspection and Test Plans.

6. Precision Geometric Control for Improved Assembly EfficiencyCompared with certain formed-plate angle sections, welded angle sections can be manufactured with controlled internal and external corner geometries according to design requirements, helping reduce assembly interference associated with fixed bending radii.
Following appropriate assembly, welding, and straightening procedures, the resulting products can provide:
Clearly controlled corner geometry
More stable straightness
Improved matching of leg dimensions and thickness
Better adaptability for node assembly
Improved compatibility with steel plates, H-sections, and other structural profiles
Greater flexibility for connection and stiffening design
