High-Temperature Performance
- ASTM TP 310S: Ideal for 3 stainless steel exhaust pipe systems in automotive and aerospace industries, maintaining structural stability up to 1150°C with exceptional creep resistance.
- ASTM TP 347H: Niobium-stabilized composition prevents carbide precipitation, making it suitable for schedule 40 stainless steel pipe applications in power plants and petrochemical reactors.
Mechanical Strength
- Tensile Strength: Both grades withstand extreme stress in high-pressure environments, such as boilers and heat exchangers.
- Bend Strength: TP 347H exhibits superior ductility for forming stainless steel pipe cutter-compatible shapes without cracking.
Corrosion Resistance
- TP 310S: Resists sulfidation and chloride-induced pitting in marine and chemical processing.
- TP 347H: Enhanced resistance to intergranular corrosion in welded components.

The weight of stainless steel pipes is calculated using:
$Weight (kg/m) = \frac{( O D - W T ) \times W T \times 0.02466}{1000}$
Where:

Example: A schedule 40 stainless steel pipe with 100 mm OD and 5 mm wall thickness weighs 11.69 kg/m.

Laser Etching/Stamping: Includes ASTM/EN standards, heat number, and grade (e.g., "TP310S" or "TP347H").
Color Coding: Optional bands for quick identification in industrial settings.

Despite their corrosion-resistant properties, rust can occur due to:

Chloride Exposure: Coastal or de-icing salt environments accelerate pitting in TP 310S.
Intergranular Corrosion: Improper welding of TP 347H without post-weld annealing.
Surface Contamination: Iron particles or grease disrupt the passive chromium oxide layer.
Low-Quality Alloys: Substandard Cr/Ni ratios reduce corrosion resistance.

Premium Material Sourcing: Strict adherence to ASTM/EN standards for 3 stainless steel exhaust pipe, schedule 40 stainless steel pipe, and stainless steel pipe cutter-ready products.
Customization: Tailored dimensions, surface finishes, and certifications (ISO 9001, PED, SGS).
Global Applications: Proven performance in offshore platforms, pharmaceuticals, and aerospace.
Sustainable Choice: 100% recyclable with minimal lifecycle costs.
