Key Attributes
- Heat Resistance: Maintains integrity up to 870°C (1,600°F), ideal for furnace components and mig welding stainless steel exhaust pipe retrofits.
- Corrosion Resistance: 16-18% chromium and 2-3% molybdenum resist chloride-induced pitting in marine and chemical environments.
- Low Carbon Content (≤0.03%): Minimizes carbide precipitation during welding, ensuring post-weld corrosion resistance.
- Hygienic Design: Electropolished surfaces (Ra ≤0.3μm) inhibit bacterial growth, compliant with NSF/ANSI standards.
Detailed Performance Characteristics
Tensile & Bend Strength
- Tensile Strength: ≥485 MPa ensures structural reliability in high-pressure systems like hydraulic lines and industrial boilers. The austenitic microstructure and molybdenum content enhance resistance to stress corrosion cracking, critical for welded joints in mig welding stainless steel exhaust pipe assemblies.
- Bend Strength: Exceptional ductility allows tight-radius bends without cracking. For guidance on how to bend stainless steel pipe, use cold-forming techniques (e.g., press brake or roll bending) to avoid work hardening.
Identification Methods
- Laser Etching/Stamping: Permanent markings include grade ("316L"), OD, thickness, and heat number per ASTM A480.
- Certification: Mill Test Reports (MTRs) validate chemical composition (Cr, Ni, Mo) and mechanical properties for full traceability.
Weight Calculation
Use the formula:
Example: A 100mm OD pipe with 5mm wall thickness weighs ~11.6 kg/m. For competitive pipe stainless steel price quotes, request a detailed quote based on your dimensions.
Causes of Stainless Steel Rust
Despite its corrosion resistance, rust can occur under:
- Chloride Exposure: Seawater or de-icing salts disrupt the passive chromium oxide layer, causing pitting.
- Mechanical Damage: Scratches from improper handling expose raw metal to oxidation.
- Galvanic Corrosion: Contact with dissimilar metals (e.g., carbon steel) accelerates degradation.
- Improper Welding: High carbon precipitation in heat-affected zones reduces corrosion resistance. Use low-carbon 316L and post-weld annealing for critical applications.
Applications
- Exhaust Systems: Mig welding stainless steel exhaust pipe installations leverage high-temperature stability and bend strength.
- Chemical Processing: Resists sulfuric acid, alkalis, and chlorides in reactors and pipelines.
- Marine Engineering: Chloride resistance for offshore platforms and ship exhausts.
