The chemical composition of 316 stainless steel sheet is mainly ≤0.035% phosphorus, ≤0.03% sulfur, 10.0-14.0% nickel element, 16.0-18.5% chromium element, and 2.0-3.0% molybdenum element. Its performance is also very good, tensile strength (Mpa) 620 MIN, yield strength (Mpa) 310 MIN, elongation (%) 30 MIN, area shrinkage (%) 40 MIN, density is 8.03 g/cm3.

316 stainless steel plate due to the addition of the alloy element molybdenum, so its corrosion resistance, atmospheric corrosion resistance and high-temperature strength are particularly good, can be used in harsh environments, its excellent work-hardening properties, also has a good high-temperature strength, the solid solution state of the product is non-magnetic, in addition to its cold-rolled plate appearance glossy, but its price is higher compared to 304 stainless steel. It is mainly used to manufacture seawater or higher corrosive environment equipment.

410 stainless steel plate as a representative of martensitic steel, despite its high strength, but not suitable for application in strictly corrosive environments. Its machining properties are excellent and its main uses are knife blades, mechanical parts, oil refining devices, bolts, nuts, pump rods, and Class 1 cutlery.

The most used daily stainless steel models are 304, 316 stainless steel, the most important difference between the two in chemical composition is that 316 contains molybdenum, and a wide consensus is that 316 stainless steel has better corrosion resistance than 304 in high temperature environments. Therefore, in high-temperature operating environment, usually use 316 stainless steel material parts.

However, there are exceptions, in the concentrated sulfuric acid environment, and then the high temperature may not be used 316 stainless steel. Otherwise, there will be a big problem. Learn mechanical people have learned thread, remember in order to prevent thread galling at high temperatures, you need to apply a black solid lubricant, that is, molybdenum disulfide (MoS2), its two conclusions, first of all, molybdenum is indeed a high temperature resistant substances, such as molten gold with the crucible fusion is molybdenum crucible, and secondly, molybdenum is easy to react with high-valent sulfur ions to generate sulfides. So there is no kind of stainless steel can be absolutely resistant to any corrosion. In the end, stainless steel is a piece of impurity steel, although more resistant to corrosion than ordinary steel, but as long as the steel can react with other substances.

There are many types of 316 stainless steel plate, mainly divided into polished stainless steel plate, bright stainless steel plate, precision stainless steel plate, 6k surface stainless steel plate, BA surface stainless steel plate, 2b surface stainless steel plate, 8k surface stainless steel plate, mirror stainless steel plate, ultra-thin stainless steel plate, medium thick stainless steel plate, thick stainless steel plate, ultra-thick stainless steel plate.
