Hindustan Steel Corporation is a leading stockholder, supplier, and exporter of ASTM A240 / SS 316 / 316L stainless steel plates in both standard and customized dimensions. We supply 316, 316L, and dual-certified 316/316L stainless steel plates to industries that demand superior corrosion resistance, especially in chloride-rich, marine, and chemical environments.
From seawater equipment to pharmaceutical tanks and food-grade machinery, SA240 316 and 316L plates are globally trusted for their molybdenum-enhanced performance, long-term durability, and clean surface finishes.
We provide immediate dispatch from stock with full traceability, mill test certificates, EN 10204 3.1, and export packing.
ASTM A240 Grade 316 / 316L refers to austenitic stainless steel plates manufactured to meet the ASTM A240 specification. These plates are rich in chromium (16–18%) and nickel (10–14%), but what makes them unique is the presence of molybdenum (2–3%), which dramatically improves resistance to pitting, crevice corrosion, and harsh chemicals.
Alternate global designations include:
If you need stainless plates for aggressive corrosive media or salt exposure, ASTM A240 316L is the standard choice.
316 and 316L stainless steel plates are used in severe environments where standard SS 304 may fail. The addition of molybdenum makes them ideal for:
In industries where both cleanability and corrosion resistance are vital, SA240 316L stainless steel plates are an industry benchmark.
Here’s a comparative overview of mechanical strength for both grades:
| Property | 316 | 316L |
|---|---|---|
| Tensile Strength | 515 – 750 MPa | 485 – 620 MPa |
| Yield Strength (0.2% Offset) | ≥ 205 MPa | ≥ 170 MPa |
| Elongation (in 50 mm) | ≥ 40% | ≥ 40% |
| Hardness (Brinell) | ≤ 217 HBW | ≤ 217 HBW |
| Impact Toughness | Excellent at low temp | Excellent at low temp |
Both grades are non-magnetic in annealed condition, maintain strength under cryogenic conditions, and are resistant to stress corrosion cracking in chloride-rich environments.
| Element | 316 (%) | 316L (%) |
|---|---|---|
| Chromium (Cr) | 16.0 – 18.0 | 16.0 – 18.0 |
| Nickel (Ni) | 10.0 – 14.0 | 10.0 – 14.0 |
| Molybdenum (Mo) | 2.0 – 3.0 | 2.0 – 3.0 |
| Carbon (C) | ≤ 0.08 | ≤ 0.03 |
| Manganese (Mn) | ≤ 2.00 | ≤ 2.00 |
| Silicon (Si) | ≤ 1.00 | ≤ 1.00 |
| Phosphorus (P) | ≤ 0.045 | ≤ 0.045 |
| Sulfur (S) | ≤ 0.030 | ≤ 0.030 |
| Iron (Fe) | Balance | Balance |
316L = Low carbon = No carbide precipitation during welding
The ASTM A240 standard covers flat-rolled stainless steel plates, including Grade 316 / 316L, used for pressure vessels, structural components, and corrosive applications.
Equivalents and Alternate Designations:

| UNS Number | S31600 / S31603 |
| EN Standard | 1.4401 / 1.4404 |
| JIS Standard | SUS 316 / SUS 316L |
| AISI | 316 / 316L |
| Werkstoff Nr. | 1.4401 / 1.4404 |
Hindustan Steel Corporation stocks SS 316 and 316L stainless steel plates in various thicknesses, finishes, and forms suitable for fabrication, cladding, and direct application.

Form
We offer laser, plasma, and waterjet cutting services with zero burr and ±1 mm tolerance.
The key benefit of SS 316 / 316L over 304 is enhanced corrosion resistance in chloride or acidic environments, due to molybdenum (Mo) content.
Temperature Performance:
Corrosion Resistance:
Use 316L for welded structures exposed to corrosive media to avoid carbide precipitation and loss of corrosion resistance.
Welding:
Fabrication:
Machining:
316/316L plates are versatile, supporting CNC profiling, structural bending, and hygienic-grade polishing with consistent quality.
