These tubes are specifically engineered for corrosive and high-temperature environments, offering superior resistance to oxidation, pitting, and chloride-induced corrosion. TP317L, the low-carbon variant, minimizes sensitization during welding while retaining excellent mechanical properties, making it ideal for chemical processing, marine applications, and high-temperature heat exchangers.
We export 317L seamless tubes to a wide range of international markets, supplying cold drawn, bright annealed, polished, heat exchanger, condenser, mechanical, and instrumentation tubes. Our products comply with UNS S31700, UNS S31703, WNR 1.4438, WNR 1.4439, JIS SUS317/317L, and BS 317S31L standards, ensuring global compatibility.
Our commitment to quality, innovation, and timely delivery has established us as a trusted supplier to industries across Europe, the Middle East, Asia, North America, and Africa. Each tube is supplied with full documentation, including Mill Test Certificates, guaranteeing traceability, quality, and reliability.
317/317L Stainless Steel Seamless Tubes – Technical Overview
Stainless steel TP317 Seamless Tubes – Chemical Analysis & Composition
SS TP317 seamless tubes are alloyed for superior resistance to corrosion, pitting, and high-temperature oxidation. The chemical composition includes chromium, nickel, and molybdenum, which enhance performance in chloride-rich and harsh chemical environments. This precise balance of elements makes TP317L tubes ideal for chemical processing, marine, heat exchanger, and high-temperature applications.

What is the difference between TP317 and TP317L?
-
Carbon Content: TP317L has a maximum carbon of ≤0.03%, whereas TP317 has ≤0.08%.
-
Weldability: TP317L is preferred for welded assemblies because lower carbon reduces intergranular corrosion.
-
Mechanical Properties: Both grades have similar tensile strength, yield strength, and elongation, but TP317L offers slightly better welded joint durability.
-
Applications: TP317L is recommended for high-temperature, welded, and chemically aggressive environments, whereas TP317 is used where welding is minimal.
How are ASTM A269 TP317/317L seamless tubes tested?
Non-Destructive Testing (NDT): Ensures defect-free tubes.
Dimensional Inspection: Verifies OD, wall thickness, and length tolerance.
Hydrostatic Pressure Testing: Confirms structural integrity for high-pressure use.
Documentation: Supplied with Mill Test Certificates (EN 10204 3.1) for traceability.
What is the difference between cold-drawn and bright-annealed TP317/317L tubes?
Cold-Drawn Tubes: Improved dimensional accuracy, surface finish, and mechanical strength; ideal for precision instrumentation and mechanical tubing.
Bright-Annealed Tubes: Solution-annealed, stress-relieved, and corrosion-resistant with shiny surface finish; ideal for heat exchangers, condensers, and polished tubing applications.
Both types can be polished or supplied as per client-specific requirements.
