TP316 Stainless Steel Pipes & Tubes

TP316 stainless steel pipes are precision-manufactured from high-grade 316/316L stainless steel for corrosion-resistant industrial applications. With excellent resistance to salt spray, high temperatures, and oxidation, they are widely used in chemical equipment, marine structures, food machinery, and pharmaceutical piping systems. TP316 stainless steel pipes support multiple specifications, thicknesses, and surface treatments, and can be customized according to customer requirements.

TP316 is a molybdenum (Mo)-containing austenitic stainless steel. Compared with 304 stainless steel, it exhibits superior resistance to pitting and crevice corrosion in marine environments, chemical processing, and high-salinity conditions. Its low-carbon version, TP316L, provides enhanced weldability and resistance to intergranular corrosion, making it suitable for heavy-duty welded components.

• Key Advantages: High temperature/high pressure resistance, excellent resistance to chloride corrosion, non-magnetic or low magnetic.
• Applicable Standards: ASTM A312 (seamless pipes), ASTM A213 (boiler/heat exchanger tubes), ASTM A269 (general-purpose fluid tubes).
• Main Grade Equivalents: UNS S31600, 1.4401 (DIN), SUS 316 (JIS).

TP316 vs. TP304

• Corrosion Resistance: 316 contains molybdenum, with far superior resistance to chlorides and acidic/alkaline corrosion compared to 304.
• Cost: 316 is generally more expensive than 304, but offers longer service life in highly corrosive environments, providing better value.
• Selection Recommendation: Use 304 for ordinary environments; 316 is essential for coastal, outdoor, or chemical plant applications.

TP316 vs. TP316L

• Chemical Composition: 316L has a lower carbon content (≤0.035%).
• Weldability: 316L does not require solution annealing after welding and still maintains excellent resistance to intergranular corrosion.
• Selection Recommendation: For thick-walled welded structures or components operating in high-temperature environments, 316L is recommended to avoid sensitization corrosion.

TP316 Stainless Steel Pipes & Tubes Frequently Asked Questions (FAQ)

Q: Does TP316L stainless steel pipe have magnetic properties?

A: In the annealed state, TP316L has an austenitic structure and is generally non-magnetic. However, slight magnetism may occur after cold working (e.g., bending, polishing).

Q: What are the advantages of EP tubes (electro-polished tubes)?

A: Electro-polishing removes surface oxide scales and micro-protrusions, forming a dense passive film. It provides excellent corrosion resistance and prevents particle adhesion, making it an ideal choice for semiconductor and pharmaceutical industries.

Q: Do you accept small-batch or sample orders?

A: Yes. We provide custom sample services, and the minimum order quantity (MOQ) can be negotiated based on actual stock availability.
