Key Performance Properties

Tensile Strength

Advanced stainless steel h beam grades like 316L and Duplex 2205 exhibit exceptional tensile strength due to their alloy composition:

316L: Tensile strength ≥485 MPa, ideal for corrosive environments like chemical plants.
Duplex 2205: Combines austenitic and ferritic phases, achieving ≥620 MPa tensile strength for high-stress applications such as offshore platforms.
304: Provides ≥520 MPa tensile strength, widely used in architectural frameworks due to its balance of strength and formability.

Bend Strength

Cold-formed automation stainless steel h beam products demonstrate superior bend resistance. For example:

Hot-rolled 304 H-beams achieve ≥205 MPa yield strength, while cold-formed variants reach ≥350 MPa, suitable for seismic-resistant structures.
Duplex 2205 H-beams maintain bend strength even at high temperatures (up to 300°C), critical for industrial automation systems.

Identification & Marking

Each wholesale stainless steel h beam is laser-etched with traceable identifiers:

Material Grade (e.g., SUS316L).
Standard Code (e.g., ASTM A554).
Heat Number for quality tracking.
Dimensions (Flange × Web × Length).
Custom QR codes or client-specific markings are available for OEM orders.

Weight Calculation Formula

Weight (kg/m) = $\frac{( 2 \times Flange Width \times Flange Thickness ) + ( Web Height \times Web Thickness )}{1000} \times 7.93$
Example: For a 200mm (flange) × 10mm (flange thickness) × 300mm (web) × 12mm (web thickness) H-beam:
$\frac{( 2 \times 200 \times 10 ) + ( 300 \times 12 )}{1000} \times 7.93 \approx 68.2 kg/m$ .

Why Stainless Steel H-Beams May Rust?

Despite their corrosion resistance, rust can occur under specific conditions:

Chloride-Induced Corrosion: Coastal environments or exposure to de-icing salts degrade the chromium oxide layer, causing pitting.
Mechanical Damage: Scratches from improper handling or welding compromise surface integrity.
Galvanic Corrosion: Direct contact with carbon steel or copper in humid settings creates electrochemical cells.
High-Temperature Oxidation: Prolonged exposure to >300°C oxidizes surfaces, especially in 304-grade beams.
Contaminant Accumulation: Organic residues (e.g., grease) trap moisture, accelerating localized corrosion.

Preventive Measures:

Use advanced stainless steel h beam grades like 316L (2.5% Mo) for marine or chemical exposure.
Passivate welded joints to restore chromium oxide layers post-fabrication.
Implement regular cleaning with pH-neutral detergents to remove contaminants.
