Stainless Steel 316L Sheets & Plates Supplier, Stockist & Exporter
erametssteel.
ERAMETS STEEL ALLOYS PVT. LTD. supplies Stainless Steel 316L Sheets and Plates for chemical processing, pharmaceutical equipment, food and dairy plants, marine applications, process industries, engineering fabrication, pressure equipment and other demanding industrial environments.
SS 316L, identified as UNS S31603, is a low-carbon molybdenum-bearing austenitic stainless steel. Its chromium, nickel and molybdenum content provides enhanced resistance to localized corrosion compared with conventional 304-series stainless steel, particularly in environments containing chlorides and other aggressive media. The low-carbon chemistry also makes 316L well suited to welded fabrication where resistance to intergranular corrosion after welding is important.
ERAMETS supplies 316L stainless steel sheets and plates according to the required grade, standard, thickness, width, length, surface finish, edge condition, quantity, inspection requirements and documentation.
Common procurement specifications include ASTM A240 / ASME SA240 Type 316L, with material supplied in cold-rolled sheet or hot-rolled plate forms according to size and application.

What Is Stainless Steel 316L?
Stainless Steel 316L is an austenitic chromium-nickel-molybdenum stainless steel grade developed for applications requiring stronger corrosion resistance than standard 304 stainless steel.
The addition of molybdenum improves resistance to localized corrosion, including pitting and crevice corrosion, while the low carbon content helps minimize carbide precipitation during welding. 316L is therefore widely used for fabricated equipment, process systems and components exposed to corrosive industrial environments.
Common designations include:
- AISI 316L
- UNS S31603
- EN 1.4404
- EN 1.4435
- X2CrNiMo17-12-2
- X2CrNiMo18-14-3
- JIS SUS316L
- ASTM Type 316L
- ASME SA240 Type 316L
The exact EN grade and chemical range should always be confirmed against the purchase specification and material certificate. EN 1.4404 and EN 1.4435 are both associated with UNS S31603, but they are not chemically identical grades.
Stainless Steel 316L Sheets
SS 316L Sheets are generally selected for lighter-gauge applications requiring corrosion resistance, formability, surface quality and fabrication performance.
Typical applications include:
- Pharmaceutical equipment
- Food processing equipment
- Dairy equipment
- Chemical processing equipment
- Laboratory equipment
- Architectural fabrication
- Marine-related equipment
- Industrial enclosures
- Kitchen and commercial equipment
- General engineering
Cold-rolled 316L sheets can be specified where tighter dimensional control and a controlled surface finish are required.
Stainless Steel 316L Plates
SS 316L Plates are used for heavier fabrication and industrial applications where greater thickness is required.
Typical applications include:
- Process equipment
- Chemical tanks
- Storage vessels
- Pressure equipment
- Heat exchanger components
- Industrial platforms
- Fabricated structures
- Pulp and paper equipment
- Pharmaceutical processing equipment
- Flanges and fabricated components
316L is available in both cold-rolled and hot-rolled product forms, while heavier plate applications are generally supplied as hot-rolled plate.

Pharmaceutical Industry
316L is widely selected for pharmaceutical processing equipment because of its corrosion resistance, weldability and suitability for hygienic fabrication. Typical applications include process equipment, tanks, vessels, equipment panels and fabricated components.
Chemical Industry
The molybdenum-bearing composition makes 316L suitable for many chemical-processing environments where higher corrosion resistance than 304 stainless steel is required.
Food & Beverage Industry
Applications include food-processing machinery, tanks, equipment panels, preparation equipment and fabricated assemblies.
Dairy Industry
316L can be used for dairy-processing equipment, storage vessels and hygienic fabrication where the specified operating environment requires the grade.
Marine Applications
316L is frequently considered for marine and chloride-containing environments because of its molybdenum-containing composition.

Frequently Asked Questions
What is SS 316L?
SS 316L is a low-carbon, molybdenum-bearing austenitic stainless steel identified as UNS S31603. It is widely used where better corrosion resistance than 304-series stainless steel is needed, and where welded fabrication is involved.
What is the difference between SS 316 and SS 316L?
The primary difference is carbon content. 316L has a lower carbon limit (0.030% maximum in ASTM A240), which helps reduce carbide precipitation during welding.
What is the difference between SS 304L and SS 316L?
SS 316L contains about 2–3% molybdenum, which gives higher resistance to localized corrosion in many chloride-containing environments. SS 304L has no intentional molybdenum addition. The grade should be selected according to the actual operating environment.
Are EN 1.4404 and EN 1.4435 the same?
Both correspond to 316L / UNS S31603, but they are not chemically identical. EN 1.4435 generally has higher nickel and molybdenum ranges than EN 1.4404, so the required EN number should be stated in the purchase order.
Which standard applies to SS 316L sheets and plates?
ASTM A240 / ASME SA240 Type 316L is commonly specified for chromium and chromium-nickel stainless steel plate, sheet and strip.
Is SS 316L available in both cold rolled and hot rolled form?
Yes. 316L can be supplied as cold-rolled sheet and as hot-rolled plate, depending on thickness, size and application. Heavier plate applications are generally supplied hot rolled.
What finishes are available for SS 316L sheets and plates?
Depending on product form, thickness and processing route, common finishes include 2B, BA, No.1, No.4, Hairline and Mirror.
What documents can be supplied with SS 316L sheets and plates?
Depending on the order, documentation can include Mill Test Certificates, heat-number traceability, chemical and mechanical test results, EN 10204 3.1 documentation and third-party inspection reports where specified.
What information is required for an SS 316L quotation?
Send the grade (and EN number if required), standard, product form, condition, thickness, width, length, finish, quantity, inspection and documentation requirements, and delivery location.
