Detailed Technical Descriptions
1. Tensile & Bend Strength
446 stainless steel tubes & pipes exhibit exceptional mechanical performance, with a tensile strength of ≥515 MPa and yield strength of ≥335 MPa. This makes them ideal for high-stress environments like combustion chambers and industrial boilers. The bend strength is enhanced through controlled annealing processes, ensuring structural integrity even under cyclic loading.
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., 446, 304L)
- 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 in 446 stainless steel tubes & pipes may occur due to:
- Chloride Exposure: Prolonged contact with seawater or de-icing salts can cause pitting.
- Galvanic Corrosion: Avoid pairing with dissimilar metals in humid environments.
- High-Temperature Oxidation: While 446 steel resists scaling up to 1082°C, extreme thermal cycling may degrade protective oxide layers.
