What is 317L Stainless Steel Pipe
317L a large type part of low-carbon austenitic stainless-steel pipe along with iron, chromium and molybdenum is their essential factor. It has been specifically formulated to offer improved corrosion resistance against a wide range of chlorides found in industrial service.
Key Characteristics:
317L contains low levels of Carbon and has a maximum carbon content of 0.03%, which means it is less susceptible to sensitisation during welding, helps in retaining the structure’s integrity.
Good Corrosion Resistance: The molybdenum content enhances the resistance to pitting and crevice corrosion in both a neutral/chloride environment.
Properties: Good mechanical properties can resist high temperature.
Common Applications:
The applications of 317L stainless steel pipe are widespread and used in the chemical processing, oil & gas, pharmaceuticals among other heavy duty industries that require a corrosion resistant/ durable hot rolled product.
Ultimately, 317L stainless steel pipe is a go-to solution or applications after high performance where corrosion resistance on the element of key properties.
Cold Rolling of 317L Stainless Steel Pipe?
Although the superior attributes bring many advantages into machining, UNS S32760 machinability encounters some problems regarding high strength, hardness, and high alloys content. This may cause more wear, greater cutting forces, and even potential work-hardening during machining. Applying appropriate tooling, cutting methods, and coolant application can ensure better management of such a situation.
Composition: 317L is a low-carbon version of 317, which has an 18%-20% chromium content and 11-14% nickel. With such high alloying elements as molybdenum providing a good corrosion resistance (3~4.5%), especially in chloride environments Low Carbon Content. There is little carbon in 317L, shown by the “L” in its name. This the fact that it will not produce any harmful reaction products after it has been accelerated to temperatures up to 1000°C for an extended period will improve its resistance to intergranular Corrosion Resistance.317L is a kind of steel especially resistant to pit and crevice corrosion and general corrosion. In this respect it is used in the chemical process industries, food production industries (Ferritic surface-finish equipment such as dough kneards), and marine environments.

Application of 317L Stainless Steel
The 317L stainless steel is having the features like high strength capabilities and due to it, it has become good for widespread applications in industries. Check out the some essential uses of it.
317L Stainless Steel Applications:
Chemical Processing: For use in the synthesis and storage of caustics, mineral acids and metal chlorides.
Oil and Gas: The pipeline, valves and fitting when used to be in contact with harsh environment as it can withstand the heavy corrosion medium.
Pharmaceuticals: Used in machinery and duct systems where cleanliness is top priority.
Food and Beverage Processing: Ensured tanks, piping and other equipment met UDWI health regulations.
Marine Applications: For applications in seawater and other saline environments, such as boat fittings, offshore constructions etc.
Power Generation: Employed in aggressive gas and high temperatures conditions (process parts of power plants).
Pollution Control: Utilized in scorchers and different gear intended for acidic or ignitable gases.
Textile Industry: Used in equipment for dyeing and other corrosive chemicals disinfection.
