Stainless Steel 316L Plates Manufacturer & Supplier

Stainless Steel 316L plate is an austenitic, molybdenum-bearing flat-rolled product covered under ASTM A240 and ASME SA-240. Designated as UNS S31603 (Werkstoff 1.4404), this grade contains 16.0-18.0% chromium, 10.0-14.0% nickel, and 2.00-3.00% molybdenum with a maximum carbon content of 0.030%. That low carbon level is the defining characteristic: it prevents chromium carbide precipitation during welding, giving 316L plates superior resistance to intergranular corrosion in the heat-affected zone.

Minimum tensile strength is 485 MPa (70 ksi), yield strength is 170 MPa (25 ksi), and elongation is 35% in 2 inches. Molybdenum in the alloy matrix improves pitting and crevice corrosion performance in chloride-rich and acidic environments. Chemical processing, marine structures, food manufacturing, and pharmaceutical equipment are the primary application sectors.

Industrial Applications of 316L Stainless Steel Plates

These plates find their place in four key industrial sectors. Corrosion resistance, the ability to be welded, and mechanical strength are all critical attributes for these applications.

Chemical and Petrochemical Processing

Chemical and petrochemical processing applications employ 316L plates to line reaction vessels, heat exchangers and storage tanks. Molybdenum in the alloy enhances its resistance to pitting corrosion, particularly in chloride-containing environments.

Marine and Offshore Equipment

Saltwater exposure demands a grade that resists chloride-induced stress corrosion cracking. 316L plates are used for hull fittings, offshore platform components, and desalination equipment where prolonged seawater contact is unavoidable.

Food Processing and Pharmaceutical Equipment

Hygienic processing lines require a non-reactive surface that tolerates frequent CIP (clean-in-place) wash cycles. 316L's low carbon composition prevents contamination and maintains surface integrity over repeated sanitisation with acidic cleaning agents.

Architectural and Structural Applications

Benefit from 316L's ability to resist atmospheric corrosion over time, especially in coastal areas and polluted urban environments. The 2B and #4 finishes provide an attractive appearance for visible installations.

316L vs 316 Stainless Steel Plates: Key Differences

316L and 316 stainless steel plates are closely related grades, differing primarily in carbon content, a small distinction that significantly impacts weld performance, corrosion resistance, and mechanical strength.

Tensile Strength (min)	75 ksi	70 ksi
Yield Strength (min)	30 ksi	25 ksi
Sensitisation Risk	Higher	Lower
Intergranular Corrosion Resistance	Standard	Superior (esp. in heat-affected zones)
Weld Suitability	Moderate	Preferred for heavy welding
Dual Certification	Often meets 316L too	Often meets 316 too
Best For	General structural use, minimal welding	Welded assemblies, corrosive environments

Frequently Asked Questions:

What is the rate of SS 316L Plate per kg? +

SS 316L plate prices in India hover around ₹320-350 per kilogram. Prices around the world vary, influenced by the plate's thickness, the finish applied, and the size of the order. To get the latest pricing details, contact Sachiya Steel International.

How thick is a SS 316L Plate? +

316L plates per ASTM A240 are available in thicknesses from 3/16″ (4.76 mm) to 2.5″ (63.5 mm). Custom thicknesses outside this range can be sourced on request.

Which is better for Plates: 316 or 316L? +

316L plates are the better choice for welded fabrications and corrosive environments because the lower carbon content (0.030% max vs 0.08%) prevents intergranular corrosion. Standard 316 offers slightly higher tensile and yield strength. Most stock today is dual-certified 316/316L.

What is the standard size of SS 316L Plates? +

Standard sizes include 4×8 ft (1220×2440 mm), 5×10 ft (1524×3048 mm), and 5×20 ft (1524×6096 mm). Cut-to-size options and non-standard dimensions are available as per client specification.

What ASTM specification covers 316L Stainless Steel Plates? +

ASTM A240 / ASME SA-240 is the primary specification. ASTM A666 also covers annealed and cold-worked 316L plate, while AMS 5507 and AMS 5524 apply to aerospace applications.

Can 316L Stainless Steel Plates be welded? +

Yes. 316L plates are known for their excellent weldability. The low carbon content, which is a maximum of 0.030%, reduces the formation of carbides during welding. This, in turn, lowers the risk of intergranular corrosion in the areas affected by heat. As a result, post-weld annealing is usually unnecessary for standard plate thicknesses.

What is the HSN code for SS 316L Plates? +

SS 316L plates generally get classified under HSN code 7219. This applies to flat-rolled stainless steel products that are 600 mm wide or wider. If the plates are narrower than that, they'll fall under 7220. To be sure you're using the right subheading, check with your customs broker, taking the plate dimensions into account.

What surface finishes are available for 316L Plates? +

Available finishes include HRAP (Hot Rolled Annealed and Pickled), 2B Mill Finish, #4 Brushed Polish, #8 Mirror, and Bright Annealed (BA). HRAP is the standard industrial finish; 2B and #4 are specified for architectural and decorative work.
