316 stainless steel sheet is the flat-rolled form of austenitic grade 316, an 18\/10 chromium-nickel alloy with 2 to 3 percent molybdenum. That molybdenum is the difference between 316 and the more common 304, and it is why 316 is the grade buyers reach for when the job involves salt, chlorides, acids, or coastal air. Wanzhi Group rolls, finishes and exports 316 sheet from its own mill in thicknesses from 0.1 to 6.0 mm, widths up to 1200 mm, and a full set of surface finishes, and ships it against ASTM A240 with a mill test certificate.<\/p>\n\n\n\n

This page expands on our existing product page with the chemistry, the finishes and sizes on offer, where the sheet actually gets used, how to choose between 316 and 304, and what moves the price. If your project sits near the sea or handles chlorides, our dedicated marine grade stainless steel sheet<\/a> page goes deeper on coastal and offshore selection.<\/p>\n\n\n\n

What 316 stainless steel sheet is<\/h2><\/div>\n\n\n\n

316 belongs to the austenitic 300 series. Like 304, it gets its corrosion resistance from roughly 17 to 18 percent chromium and its formability from 10 to 14 percent nickel. What sets it apart is the 2 to 3 percent molybdenum, an element that toughens the passive film against chloride attack. The International Molybdenum Association<\/a> explains how this small addition lifts pitting resistance by a wide margin in chloride environments, which is exactly where 304 tends to fail first.<\/p>\n\n\n\n

316 sheet is supplied as flat product in the thin-to-medium range. Thin, coil-derived material under about 3 mm is called sheet; thicker, individually cut flat product from 3 mm up is called plate. Our hot rolled stainless steel plate<\/a> guide covers the heavier end of the same 316 family. Both start from the same 316 chemistry.<\/p>\n\n\n\n

The low-carbon version, 316L, keeps carbon at 0.03 percent or below so the sheet resists sensitization and intergranular corrosion after welding without post-weld heat treatment. For most welded tanks and fabrications, 316L is the safer spec, and we stock it alongside standard 316.<\/p>\n\n\n\n

Chemical composition and ASTM A240 specs<\/h2>\n\n\n\n

316 stainless steel sheet is made to ASTM A240 \/ A240M, the US standard that covers chromium, chromium-nickel and chromium-manganese-nickel stainless plate, sheet and strip, together with ASTM A480 for finishing. The typical composition sits in this range:<\/p>\n\n\n\n

Element316 (typical, %)316L (max, %)Carbon0.08 max0.03 maxManganese2.00 max2.00 maxChromium16.0 to 18.016.0 to 18.0Nickel10.0 to 14.010.0 to 14.0Molybdenum2.00 to 3.002.00 to 3.00Silicon1.00 max1.00 maxPhosphorus0.045 max0.045 maxSulfur0.030 max0.030 max<\/p>\n\n\n\n

The molybdenum content is what moves the pitting resistance equivalent number (PREN) up. PREN is calculated as percent chromium plus 3.3 times percent molybdenum plus 16 times percent nitrogen. A typical 316 lands around 24 to 26, while 304 sits near 18 to 20. The higher the number, the better the sheet resists pitting in chloride service. Our ASTM A240 certified stainless steel sheet<\/a> page goes into the testing and certification behind the standard. In China the same grade is written 06Cr17Ni12Mo2, and the European and Japanese equivalents are EN 10088-2 1.4401 and JIS G4304 SUS316.<\/p>\n\n\n\n

For thickness beyond 6.0 mm, see our 316 stainless steel plate<\/a> range, which covers 3 to 120 mm. Weight is easy to estimate: 316 density is about 8.0 g per cubic centimeter, so a 1 mm thick, 1 square meter sheet weighs roughly 8 kg. Multiply thickness in millimeters by 8 to get kilograms per square meter.<\/p>\n\n\n\n

Surface finishes for 316 sheet<\/h2>\n\n\n\n

Finish does not change the alloy, but it changes how the sheet looks, cleans and performs in service. We supply 316 in the common rolled and polished states. 2B is the standard cold-rolled, annealed and pickled finish: smooth, dull grey, no reflection, and it is the workhorse for tanks and fabrication. No.1 is the hot-rolled, pickled finish for plate, matte and rough, for structural and heavy use. No.4, also called brushed, adds a one-direction satin grain that hides fingerprints and scratches, which is why it dominates kitchens and food equipment. BA, or bright annealed, is smooth and near-mirror, picked when appearance matters. HL is a fine, long-grain brushing for premium architectural cladding.<\/p>\n\n\n\n

Our stainless steel surface finish guide<\/a> compares 2B, No.4 and BA side by side, and the brushed stainless steel sheet<\/a> page covers the satin option in detail. After any mechanical finish we passivate the sheet to rebuild the chromium layer, which matters most on 316 used in marine and chemical service.<\/p>\n\n\n\n

Why 316 resists corrosion better<\/h2>\n\n\n\n

Corrosion resistance in stainless steel comes from a thin chromium oxide film on the surface. In clean air that film forms on its own and heals quickly. The problem starts with chlorides, which can break the film locally and start pitting. Molybdenum closes those gaps in the film and slows the attack, so 316 keeps protecting the steel where 304 would stain and pit within a season.<\/p>\n\n\n\n

That single advantage is why 316 is specified for seawater cooling systems, coastal buildings, chemical plants and anything that sees salt or cleaning chemicals. The Britannica overview of stainless steel<\/a> describes the family and why chromium is the main element; molybdenum is the booster that 316 adds on top. A practical note: 316 is not immune. In warm, stagnant seawater or heavy crevice conditions, even 316 can pit, and that is where duplex 2205 or higher-alloy grades earn their place. For most coastal and chemical work up to moderate temperature, 316L is the right, cost-effective call.<\/p>\n\n\n\n
