Detailed Technical Insights
Tensile & Bending Strength
Stainless steel 304 pipes & tubes stockists prioritize Grade 304 for its balanced mechanical performance. With tensile strength ≥520 MPa and yield strength ≥205 MPa, it resists deformation under high-pressure applications like structural frameworks and heat exchangers. Cold-rolled processing enhances grain uniformity, while annealing (heated to 1010–1120°C) ensures ductility for bending and welding.
Grade 316, ideal for marine environments, maintains tensile strength ≥515 MPa even in chloride-rich conditions, thanks to 2–3% molybdenum content.
Weight Calculation
Use the formula to estimate pipe weight:
Example: A 100mm OD × 10mm WT × 10m pipe weighs 231.85 kg.
Identification & Marking
- Laser Etching: ASTM/AISI grades (e.g., "304") and manufacturer codes on pipe surfaces.
- Color Coding: Blue for 304, yellow for 316, and red for 201 in cost effective stainless steel pipes and tubes.
Why Stainless Steel Rusts
Despite corrosion resistance, rust can occur due to:
- Chloride Exposure: Coastal or industrial areas degrade passive chromium oxide layers. Grade 316 mitigates this with added molybdenum.
- Mechanical Damage: Scratches during installation expose raw steel. Use nylon tools and protective films.
- Galvanic Corrosion: Contact with carbon steel or aluminum. Insulate with dielectric fittings.
- Low Chromium Content: Grades like 201 (16% Cr) are less resistant than 304 (18% Cr).
Applications of China Stainless Steel Pipe Tube
- Sanitary Systems: Stainless steel 304 pipes & tubes stockists supply mirror-finished pipes for food processing and pharmaceuticals.
