If you are looking for 3mm 316 stainless steel sheet, GNEE offers products suitable for applications in chemical processing, food processing, marine equipment, pharmaceuticals, construction, and industrial equipment manufacturing. We can provide various surface finishes, dimensions, and delivery conditions tailored to specific project requirements.

 

GNEE supplies 3mm-thick 316/316L stainless steel sheets. Common specifications include 1000×2000 mm, 1219×2438 mm, 1220×2440 mm, 1500×3000 mm, and 1500×6000 mm; we also support cut-to-size services based on customer drawings. Materials comply with standards such as ASTM A240/ASME SA240, EN 10088, and JIS G4304. To ensure material traceability, we provide Mill Test Certificates (MTC), EN 10204 3.1 certification, and reports covering PMI, chemical composition, mechanical properties, and dimensional inspections. Compared to 304 stainless steel, 316 stainless steel offers superior resistance to chloride corrosion, making it particularly suitable for environments involving salt, moisture, and mild chemical exposure.

 

Regarding supply capabilities, GNEE provides 3mm 316 stainless steel sheets in full-size plates, cut-to-size sheets, and bulk orders. We also offer value-added processing services such as laser cutting, CNC cutting, edge trimming, drilling, and surface finishing.

Chemical Composition (Typical Values)

According to the ASTM A240 standard, the chemical balance of Type 316 and its low-carbon variant 316L must meet the following criteria to ensure maximum corrosion performance.

Element	Grade 316 (%)	Grade 316L (%)
Chromium (Cr)	16.0 – 18.0	16.0 – 18.0
Nickel (Ni)	10.0 – 14.0	10.0 – 14.0
Molybdenum (Mo)	2.00 – 3.00	2.00 – 3.00
Carbon (C)	0.08 max	0.030 max
Manganese (Mn)	2.00 max	2.00 max
Silicon (Si)	0.75 max	0.75 max
Nitrogen (N)	0.10 max	0.10 max

316 stianless steel plate Surface Finishes

2B Finish: Cold-rolled, heat-treated, and pickled. A smooth, slightly reflective industrial finish suitable for most applications.

BA (Bright Annealed): Processed in a controlled atmosphere furnace to maintain a mirror-like, highly reflective surface.

No.4 / HL (Hairline): Brushed finish with a visible grain, ideal for architectural panels and kitchen equipment.

No.1 Finish: Hot-rolled and annealed. A dull, rougher surface used where aesthetics are secondary to corrosion resistance.

Applications of 3mm 316 Stainless Steel Plate

Marine Components: Marine fittings, heat exchangers, and coastal infrastructure.
Chemical Processing: Pressure vessels, storage tanks, and piping systems for acidic environments.
Food & Beverage: Equipment requiring high hygiene standards and frequent cleaning with strong chemicals.
Environmental Protection: Flue gas scrubbers and wastewater treatment infrastructure.

 

Standard packaging

Following packaging inspection, goods are prepared for export using moisture-proof film, wooden crates, or wooden pallets, with international shipping arranged according to trade terms such as FOB or CIF. For procurement projects with specific requirements regarding dimensions, surface finishes, and quantities, GNEE provides a comprehensive one-stop service covering material confirmation, custom sizing, quality inspection, export packaging, and final delivery.

FAQ

What is the difference between 316 and 316L for 3mm sheets?
316L is the low-carbon version of 316. While both offer similar corrosion resistance, 316L is preferred for 3mm sheets that require extensive welding, as the lower carbon content prevents carbide precipitation in the weld zone, maintaining corrosion integrity.

 

Can 3mm 316 stainless steel rust?
While 316 is highly resistant, it is not "rust-proof." In extreme conditions-such as prolonged exposure to concentrated warm seawater or stagnant high-chloride solutions-pitting can occur. Proper surface cleaning and passivation according to ASTM A967 can mitigate these risks.

 

How do I verify the quality of a 3mm 316 sheet?
Always request a Mill Test Certificate (MTC) that confirms the chemical composition and mechanical properties align with ASTM A240 or EN 10088 standards. Visual inspection for surface defects and dimensional checks against thickness tolerances are also recommended.
