Detailed Technical Descriptions
1. Tensile & Bend Strength
Our stainless steel 304L pipes and tubes are engineered to withstand extreme mechanical stress. The tensile strength (≥515 MPa) ensures durability in high-pressure environments, while bend strength is enhanced through controlled annealing processes. For stainless steel 304 pipes & tubes stockists, we offer Grade 304 with a balanced composition (18% Cr, 8% Ni) for optimal strength-to-weight ratios in construction and machinery.
2. Weight Calculation
Use the formula below to estimate pipe weight per meter:
Weight (kg/m) = (OD – Wall Thickness) × Wall Thickness × 0.02466
Example: A 50mm OD pipe with 2mm wall thickness weighs ≈2.42 kg/m.
3. Identification Marking
All products are laser-etched with:
- Grade (e.g., 304L, 316L)
- Size (OD × Wall Thickness × Length)
- Certification (ASTM/EN Standard, Heat Number)
- Manufacturer Logo
This ensures traceability and compliance with international standards.
4. Causes of Stainless Steel Corrosion
Despite inherent rust resistance, corrosion may occur due to:
- Chloride Exposure: Prolonged contact with seawater or de-icing salts can pit 304-grade steel.
- Intergranular Attack: Low-carbon 304L mitigates this risk in welded joints.
- Galvanic Corrosion: Avoid pairing stainless steel with dissimilar metals in humid environments.
Our 316L pipes (2-3% Mo content) offer enhanced resistance to chlorides and acids.
