AISI 317L Seamless Tube and 317 Stainless Steel Tubing supplier in India
What is 317L Stainless Steel Tube?
The Stainless Steel 317L Tube is made of a low carbon austenitic stainless steel, which shows improved resistance to corrosion. The 317L Stainless Steel Tube is known for offering better general and localized corrosion when compared to the 316L grade stainless steel. The ASTM A213 TP317L material is known for its good formability and weldability. The 317 Stainless Steel Tubing solutions are well-known for showing increased resistance to chemical attacks, especially from acids.

ASTM A213 TP317L and SS 317L Welded Tube according to ANSI/ ASME
Due to the low carbon content in the 317L Tubing material, it shows better resistance to sensitization when it is welded. It is also non-magnetic in nature.
Top 5 differences between 317 Stainless Steel Tube and SS 317L Tubing
The 317 SS Tubing solution is a higher strength alternative to the 316 grade ss. It consists of large amount of chromium, molybdenum, and nickel in its chemical composition. It also shows better corrosion resistance than 316 grade.
The SS 317L Heat Exchanger Tube is the low carbon variant of the 317 ss. The 317L Hydraulic Tube material shows greater strength when welded and thus the products are also stronger. Like 317, the 317L Instrumentation Tube does not get hardened from heat treatment. This is why these tubes are ideal for high temperature applications that experience high rate creep, chemical corrosion, and stress-to-rupture.

How AISI 317L Seamless Tubes are different from Alloy 317LMN?
They 317lmn and AISI 317L Seamless Tube have differences in their chemical composition. The Alloy 317LMN has slightly higher content of molybdenum and nitrogen than the 317L SS Boiler Tubes material. 317lmn material is known for its superior resistance to both generalized and localized corrosion, compared to the EN 1.4438 Superheater tubes and most other media. It is because of the presence of higher molybdenum content.
This grade also has enhanced strength when compared to the UNS S31703 Condenser Tube. Also, the 317lmn grade can be hardened by cold working and not by any kind of heat treatment. They are mostly used in pharmaceutical and food processing applications.
Why 317L Tubing is a recommended material for heat exchanger and Boiler
Due to the low carbon content in the 1.4438 Stainless Steel Coiled Tubing, they offer excellent resistance to sensitization during the welding procedure. The SS 317L Welded Tube also shows good stress to rupture at elevated temperatures.
One of the top advantages of 317L Bright annealed tube, apart from aesthetic appearance, is that they do not get hardened by heat treatment. And that is why they can be easily used in various high temperature applications. Renowned 317L Tube stockist recommend the products for heat exchangers and boilers.
Fabrication of ss 317L tubing
There are multiple stages in the production of SS 317L tubing.
- The first step in the fabrication of SS 317L is choosing the materials to use.
- Then the tubing is drawn through a die to create the intended size and shape, known as "tube drawing."
- By annealing the pipe, stresses are relieved, and flexibility is increased.
- The pipe is washed to remove any dirt or grime on the outside.
- A tube is usually cut to the desired length.
- Tubing is bent using a bending machine into the desired form.
- The tubing is welded together to create the finished product.
- Tubes are finished by polishing to increase their resistance to corrosion and enhance their aesthetic appeal.
- The finished tubing is examined to guarantee it satisfies all quality and dimensional requirements.

When working at high temperatures, the pressure rating of SS 317L tubes is influenced by various aspects, including their diameter, wall thickness, and operating temperature.
Because its mechanical properties (such as tensile strength, yield strength, and hardness) diminish with increasing temperature, the pressure rating of SS 317L tubes decreases at higher temperatures. Therefore, the tubing's working temperature must be considered when calculating the pressure rating.
For instance, at 1000 degrees Fahrenheit (538 degrees Celsius), the ASME Boiler and Pressure Vessel Code specifies a pressure rating of about 1662 pounds per square inch (psi) for a seamless section of SS 317L tubing with a wall thickness of 0.154 inches (3.91 millimeters) and a diameter of 1 inch (25.4 millimeters) (11.4 MPa).
However, when working at a cooler 500 degrees Fahrenheit (260 degrees Celsius), the pressure rating rises to around 2748 psi (18.9 MPa).
