Features of Inox 317L

In comparison to 316L, type 317L round bar is more resistant to seawater and SCC. It is commonly used in chemical equipment, such as chemical ships, and chemical products, such as reactors. With respect to chemical composition, 317L contains 2% more chromium, nickel, and molybdenum than 316, which determines stainless steel performance to a greater degree. 317 stainless steel properties is different from 317l stainless steel properties.

As far as pitting resistance is concerned, 317 is more resistant than 304 and 316. The high molybdenum guarantees that 317L is more resistant to corrosion in most media, including sulfuric acid, chlorine, and phosphoric acid. In strong oxidizing acids such as nitric acid, however, 317L has poor corrosion resistance. In general, 317L has similar performance to 317. The lower carbon content in 317L results in better welding performance and intergranular corrosion resistance at high temperatures (427~816 °C).

Various Industry Applications of Stainless Steel 317L including:

Aircraft and Aerospace: 

This makes 317L stainless steel ideal for aircraft that operate in different temperatures, elevations, and precipitations, as it is resistant to consumption and ready to withstand even the harshest environmental conditions. Additionally, the material is very durable, which is essential when operating in the air.

High-Pressure Energy Systems: 

Treated steel is likewise capable of containing high temperatures and weights, making it an ideal choice for vitality generation, including on-site power plants and military applications that require a remote location.

Medical Equipment: 

Considering the fact that restorative equipment is often used, it is imperative for this apparatus to be in good condition and ready to be cleaned effectively. 317L steel provides devices and other medicinal apparatuses with this level of tidiness.

Oil And Gas Sourcing: 

A 317L stainless steel alloy is also used in the extraction of natural gas and oil from the earth’s surface. These alloy materials are ideal for these applications because they can withstand the high temperatures and pressures that are present under the ground’s surface.

Food Processing: 

It is a good idea to use type 317L stainless steel for food manufacturing, as it offers clean, corrosion-free tools and surfaces with which food can be made and packaged, ensuring a healthy environment for consumers.Welding and other thermal processes are resistant to sensitization due to the low carbon content.

General Properties

It is a lowcarbon corrosion resistant austenitic stainless steel with chromium, nickel, and molybdenum content that is also known as alloy 317L (UNS S31703). Due to its high levels of these elements, the alloy has superior chloride pitting and general corrosion resistance than the conventional 304/304L and 316/316L grades in terms of chloride pitting. In strongly corrosive environments containing sulfuric media, chlorides, and other halides, this alloy provides improved resistance as compared to 316L.

As a result of the low carbon content of Alloy 317L, it can easily be welded without causing intergranular corrosion due to chromium carbide precipitation, allowing it to be used as-welded. As a result of the addition of nitrogen as a strengthening agent, the alloy can be dual certified as Alloy 317 (UNS S31700) and 317 (UNS S31700).

In the annealed condition, Alloy 317L does not exhibit the properties of a magnetic alloy because it is non-magnetic. The material cannot be hardened by heat treatment, however, cold working will cause the material to harden. Alloy 317L can be easily welded and formed by standard shop fabrication methods.

Corrosion Resistance

When compared to stainless steels such as 304/304L and 316/316L, Alloy 317L has a high molybdenum content, which provides superior corrosion resistance in many media. In normal situations, environments that are not acidic to 304/304L stainless steel will not corrode 317L stainless steel. However, nitric acid, a strongly oxidizing acid, will not corrode SS 317L.  Alloys that contain molybdenum tend to behave differently in such environments.

In food and pharmaceutical processing, alloy 317L is used in a wide variety of applications that require corrosion resistance against a wide range of chemicals. It is resistant to attack from sulfuric acid, acidic chlorine and phosphoric acid. It is also used in handling hot organic and fatty acids which are present during food and pharmaceutical processing.

If the alloy is exposed to temperatures in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C), the corrosion resistance of 317 and 317L will be the same. However, there is one exception where the alloy must be exposed to temperatures within that range. To guard against intergranular corrosion, 317L is the preferred material in this service due to its low carbon content.

Due to its higher molybdenum content, 317L stainless steel is somewhat more resistant to stress corrosion cracking than 304/304L stainless steel, but it is still subject to stress corrosion cracking when used in halide environments due to its higher molybdenum content.

317L pipe is more resistant to pitting and crevice corrosion when chlorides and other halides are present because of its higher chromium, molybdenum, and nitrogen content. This chart compares Alloy 317L to other austenitic stainless steels on a basis of Pitting Resistance Equivalent including Nitrogen Number (PREN).
