Key Attributes & Processing

Category	Description
Chemical Composition	304: 18% Cr, 8% Ni
Heat Treatment	Solution annealing (1040–1120°C) for stress relief and corrosion resistance optimization
Cold/Hot Rolling	Precision cold rolling (±0.5 mm tolerance) for tight dimensional control or hot rolling for structural bulk
Magnetic Properties	Austenitic grades (304/316) are non-magnetic; duplex grades exhibit partial magnetism

Performance Highlights

Tensile & Bending Strength

The stainless steel h beam achieves exceptional tensile strength, with Grade 316 exceeding 550 MPa, ideal for load-bearing structures like bridges and industrial frameworks. Its bending performance is enhanced by the austenitic microstructure, which allows elongation rates above 35%, reducing fracture risks during seismic events. For high-strength applications, duplex variants (custom stainless steel h beam) provide tensile strength over 620 MPa, outperforming traditional carbon steel in corrosive environments.

Identification & Marking

Each beam is laser-etched with:

Material Grade (e.g., 304, 316, duplex).
Batch Number for traceability (ISO 10474 certification).
Manufacturer Logo and compliance marks (ASTM/EN/JIS).

Weight Calculation

Calculate beam weight using:
$Weight (kg/m) = (Flange Width \times Flange Thickness \times 2) + (Web Height \times Web Thickness) \times Density (8,000 kg/m³)$
Example: A 200×200×8×12 beam (flange: 200×12 mm, web: 200×8 mm):
$Weight = [(200 \times 12 \times 2) + (200 \times 8)] \times 8 \times 1 0^{-6} \times 8000 = 50.2 kg/m$

Corrosion Resistance & Rust Prevention

While stainless steel h beam offers superior corrosion resistance, localized rust may occur under extreme conditions:

Chloride Exposure: Coastal or de-icing environments can cause pitting in 304 grades. Upgrade to 316 or duplex for chloride-rich settings.
Mechanical Damage: Scratches during installation expose the base metal. Passivation treatments restore the chromium oxide layer.
High-Temperature Oxidation: Prolonged exposure above 870°C degrades the passive film. Use refractory coatings or opt for stabilized grades.

Why Choose Our Stainless Steel H Beam?

Material Superiority: We use only best stainless steel h beam grades (304, 316, duplex) with mill test certificates, ensuring compliance with ASTM/EN standards.
Customization Expertise: Tailor custom stainless steel h beam dimensions, surface finishes, and alloy compositions to meet project-specific demands (e.g., seismic reinforcement, coastal infrastructure).
Global Certifications: ISO 9001, CE, and PED certifications guarantee product reliability for critical applications like nuclear facilities and offshore platforms.
Fast Turnaround: 15–30 days lead time for standard sizes; expedited services available for urgent projects.
Sustainability: Our beams contain 60–90% recycled content, aligning with green building initiatives (LEED/BREEAM compliance).
