Stainless Steel Pipe | 316L High-Temp Exhaust Systems

Stainless Steel Pipe | 316L High-Temp Exhaust Systems

Product Overview

Our 316L stainless steel pipes are engineered for extreme-temperature exhaust systems, combining superior heat resistance (up to 870°C/1,600°F) with unmatched corrosion protection against chlorides, acids, and industrial pollutants. Designed for automotive, marine, and industrial applications, these pipes comply with ASTM A312/ASME SA213 standards and feature customizable stainless steel pipe dimensions chart specifications. With a mirror-polished surface (Ra ≤0.3μm) and ERW/seamless processing, they ensure leak-proof performance in high-pressure environments.

Key Attributes

1. Heat & Corrosion Resistance:
   • Withstands temperatures up to 870°C, ideal for automotive high-temp exhaust systems.
   • 16-18% chromium and 2-3% molybdenum resist chloride-induced pitting in marine and chemical environments.
2. Low Carbon (≤0.03%): Minimizes carbide precipitation during welding, ensuring post-weld corrosion resistance.
3. Customization: Tailored OD, wall thickness, and lengths (1m–12m) with deburred edges for seamless integration.

Detailed Performance Characteristics

Tensile & Bend Strength

• Tensile Strength:
  ≥485 MPa tensile strength ensures structural integrity in high-pressure systems like industrial boilers and marine exhausts. The molybdenum-enhanced microstructure prevents stress corrosion cracking, critical for welded joints.
• Bend Strength:
  Cold-drawn ERW pipes retain ductility under tight-radius bends (1.5x OD), ideal for custom exhaust layouts. Use mandrel bending tools 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:16-18%, Ni:10-14%, Mo:2-3%) and mechanical properties.

Weight Calculation

Use the formula:
Weight (kg/m)=1000(OD−WT)×WT×0.0248
Example: A 100mm OD pipe with 5mm wall thickness weighs ~11.6 kg/m. Download our stainless steel pipe dimensions chart for bulk calculations.

Causes of Stainless Steel Rust

Despite its corrosion resistance, rust can occur under:

1. Chloride Exposure: Seawater or de-icing salts disrupt the passive chromium oxide layer, causing pitting.
2. Mechanical Damage: Scratches from improper handling expose raw metal to oxidation.
3. Galvanic Corrosion: Contact with carbon steel in conductive fluids accelerates degradation.
4. Improper Welding: High carbon precipitation in heat-affected zones reduces corrosion resistance. Use low-carbon 316L and post-weld annealing.

Applications

• Automotive Exhausts: High-temperature stability for turbocharged systems and catalytic converters.
• Marine Engineering: Chloride resistance for offshore platforms and ship exhausts.
• Industrial Ducting: Custom pipe schedule chart stainless steel solutions for chemical plants and HVAC.
