317L stainless steel is one of the most widely used and versatile type of steel. 317L stainless steel is often referred to as ‘corrosion-resistant steel’ – it does not stain, corrode or rust as easily as normal carbon steel. It is an austenitic stainless steel. It is less electrically and thermally conductive than carbon steel and is essentially non-magnetic. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes

Stainless steel 317L coil is used to manufacture products in a variety of industries where extreme conditions may exist such as marine, oil & gas, chemical processing, power generation, food processing, wastewater and other applications. Stainless steel coils are also used in various architectural applications and sheet metal component manufacturing industry. Stainless steel coils can be easily formed into various shapes, and polished as per customer requirements, making it the most important raw material for sheet metal component industry. Asiamet is a stockist, supplier and exporter of high quality stainless steel coils as per ASTM A240 in various sizes and grades such as 304/304L, 316/316L, 321/321H, 347/347H & Duplex 2205.

Stainless steel 317L sheet is typically sold in the annealed condition and is available in 0.1mm to 8.0mm in cold rolled and hot rolled form. Our 317L stainless steel sheets come in both 2B finish and various polished finishes such as 2D, BA, No.1, No.4, No.8, 8K, Mirror and Matte, with PVC Coating.

Due to its anti-corrosive properties, stainless steel coils have become essential in the composition of parts for the medical, tooling, mechanical and food industries. Stainless steel coils are widely used in various industries as mentioned in the below table.

PREN for various Grades of Stainless Steel Coils

What is PREN?

Pitting resistance equivalent numbers (PREN) are a theoretical way of comparing the pitting corrosion resistance of various types of stainless steels, based on their chemical compositions. In general, the higher PREN-value, the more resistant is the stainless steel to localized pitting corrosion by chloride. The elements which have a significant impact are chromium, molybdenum and nitrogen.

The formula used to calculate PREN is as below:

PREN = %Cr + 3.3(%Mo) + 16(%N)

PREN = 1 × %Cr + 3.3 (%Mo + 0.5 × %W) + 16 × %N

Alternative Grades to Stainless Steel 317L Grade

Features
303	Stainless steel 303 grade can be used when higher machinability is needed, and lower corrosion resistance, formability and weldability are acceptable.
316	Stainless steel 316 grade can be used when higher resistance to pitting and crevice corrosion is required, in chloride environments.
321	Stainless steel 321 grade can be used when better resistance to temperatures of around 600-900°C is needed. 321 has higher hot strength.
3CR12	Stainless steel 3CR12 can be used when lower cost is required, and the reduced corrosion resistance and resulting discoloration are acceptable.
430	Stainless steel 430 grade is acceptable when a lower cost is required, and the reduced corrosion resistance and fabrication characteristic are acceptable.
