With the exploration and innovation of company people, gradually formed four major advantageous products: steel plate, steel pipe, stainless steel, special steel.
316 stainless steel chemistry316 Stainless Steel. A major difference between 304 and 316 stainless steel is the chemical composition, with 316 containing a significant amount of molybdenum; typically 2 to 3 percent by weight vs only trace amounts found in 304. The higher molybdenum content results in grade 316 possessing increased corrosion resistance.
AISI 316 Grade Stainless Steel (UNS S31600) ASTM AISI 316 stainless steel (UNS S31600) is one of the most widely used austenitic stainless steels. Due to the addition of Molybdenum (Mo), SS316 has a great improvement in corrosion resistance and high temperature strength.

Marine grade stainless steel, called type 316, is resistant to certain types of interactions. There is a variety of different types of 316 stainless steels, including 316 L, F, N, H, and several others. Each is slightly different, and each is used for different purposes. The "L" designation means 316L steel has less carbon than 316 steel.
The 316 family is a group of austenitic stainless steels with superior corrosion resistance to 304 stainless steel. This alloy is suitable for welding because it has a carbon content lower than 301 to 303 series alloys to avoid carbide precipitation in welding applications.
Two of the more commonly used grades of austenitic stainless steel are grades 304 and 316. To help you determine which grade is right for your project, this blog will examine the difference between 304 and 316 stainless steel.
317L is a molybdenum containing austenitic stainless steel, with improved corrosion resistance over 304/304L and 316/316L stainless steel. The increased levels of chromium, nickel and molybdenum over 316L stainless steel improve chloride pitting resistance and general corrosion.
316L is the low carbon version of 316 stainless steel. Covered in thsi document are the physical and mechanical properties of 316L stainless steel. Other areas such as heat treatment, welding, machining, hot and cold working, hardening, work hardening and applications are also outlined.
316 / 316L are austenitic stainless steels that contain molybdenum, which increases their resistance to many chemical corrodents and marine environments. 316L is an extra low carbon version of 316 stainless steel. These materials are more resistant to general corrosion and pitting/crevices than conventional austenitic stainless steels.
316 grade is the second-most common form of stainless steel. It has almost the same physical and mechanical properties as 304 stainless steel, and contains a similar material make-up. The key difference is that 316 stainless steel incorporates about 2 to 3 percent molybdenum.
An example of a building in which these properties are exploited is the Art Gallery of Alberta in Edmonton, which is wrapped in stainless steel. Type 316 stainless is used on the exterior of both the Petronas Twin Towers and the Jin Mao Building, two of the world's tallest skyscrapers.
General Properties. Alloy 316/316L is molybdenum-bearing austenitic stainless steel. The higher nickel and molybdenum content in this grade allows it to demonstrate better overall corrosion resistant properties than 304, especially with regard to pitting and crevice corrosion in chloride environments.
Types 316, 316L, 317 and 317L are more resistant to atmospheric and other mild types of corrosion than Types 302, 304 and 304L. In general, media that do not corrode Types 302, -containing grades. One known exception is highly oxidizing acids such as nitric acid to which the molybdenum-bearing stainless steels are less resistant.

AISI 316 vs 316L Stainless Steel (UNS S31603) Both AISI 316 vs 316L stainless steel are molybdenum (Mo) containing stainless steel grades. The main difference between 316 and 316L stainless steel is the level of carbon content, SS316 has a 0.08% max carbon content while SS316L (UNS S31603) has a 0.03% max carbon content.
The addition of molybdenum and a slightly higher nickel content make 316 Stainless Steel suitable for architectural applications in severe settings, from polluted marine environments to areas with sub-zero temperatures. Equipment in the chemical, food, paper, mining, pharmaceutical and petroleum industries often includes 316 Stainless Steel.
The differences between a 316L and a 316 straight grade are two-fold both in chemistry and mechanical properties. The L grade has a lower maximum carbon limit and the straight grade has increased mechanical properties.
Chemical compositions of AISI (ASTM/ASME) and UNS austenitic stainless steel grades Introduction - AISI ASTM ASME and UNS. Most ASTM and ASME standards list the steel grades by their UNS (Unified Numbering system) numbers but also make reference, where appropriate to the more general AISI (American Iron and Steel Institute) grade designations.
Outside of the US it is commonly known as "A2 stainless steel", in accordance with ISO 3506 (not to be confused with A2 tool steel). Type 316the second most common grade (after 304); for food and surgical stainless steel uses; alloy addition of molybdenum prevents specific forms of corrosion.
Rolled Alloys and our RA330 alloy were both created to service the need of the thermal process industries for a reliable source of a wrought alloy that could handle the rigors high temperature carburizing conditions and repeated quenching.
316 stainless steel is often used in marine applications where the steel is constantly exposed to moisture. It is also used in food and beverage processing and chemical processing applications. 308 stainless steel is often used on restaurant and distillery equipment, chemical tanks and in the manufacturing of welding wire.
