Corrosion, heat and the shop floor.

How 316 behaves in service and in fabrication.

Corrosion resistance

Better than 304 thanks to molybdenum. Resists pitting and crevice corrosion in chloride environments, for marine, coastal and chemical plant use.

Heat resistance

Good oxidation resistance in intermittent service up to 870 °C and continuous service up to 925 °C. For continuous use at 425–860 °C in corrosive conditions, 316L is preferred.

Machining

Similar to 304. Use sharp tools and enough lubrication.

Welding

Welds with all conventional techniques. Post-weld heat treatment is not needed.

Hot working

927–1204 °C.

Annealing

1038 °C, then rapid cooling.

Heat treatment

Cannot be hardened by heat treatment; it can be strengthened by cold working.

Limitations

Susceptible to stress corrosion cracking above 60 °C.

316: an excellent food-grade stainless steel.

Where food contact meets salt, acids or harsh cleaning, 316 adds a margin of corrosion resistance.

Composition

16–18% chromium, 10–14% nickel and 2–3% molybdenum.

Corrosion resistance

Higher corrosion resistance, especially against chloride ions.

Use

Commonly used for high-end kitchen appliances and equipment.

316 stainless steel FAQ.

Questions buyers ask before ordering 316.

Why is 316 called marine-grade stainless steel?

Its molybdenum content gives it superior performance in seawater, with resistance to pitting and crevice corrosion in chloride environments.

316 or 304?

316 contains molybdenum, so it resists corrosion better and costs more. Choose 316 for marine or chemical environments, and 304 for general use.

316 or 316L?

For continuous use between 425 and 860 °C in corrosive environments, 316L is preferred.

Can 316 be hardened?

Not by heat treatment. It can be strengthened by cold working.

What sizes do you supply?

Coil in 1000, 1219, 1240 and 1500 mm widths or slit to size, 0.15–3.0 mm thick. Sheet in the same widths, 2000 to 3048 mm long, 0.3–3.0 mm thick.

Our Leading Coating Technology.

Thicker coating, consistent color and easy-clean surfaces. Each one measured in our own production and compared with typical market product.
PVD coating

Thicker PVD coating

0.30µm
Typical coating thickness, up to 28% thicker than a typical market coil, so the color lasts longer.
See the coating test
Color control

Consistent color

ΔE ≤ 2
Every coil is held below the color difference the eye can see, so panels from different batches match.

Anti-fingerprint

Fingerprint-resistant

215solvent rubs
Our anti-fingerprint coating withstood 215 rubs with a strong solvent. The standard requires 100. Typical market AF failed at 70.
