Stainless Steel 316L Features and Applications

Stainless steel coil grades 316 and 316L are similar in terms of their chemical composition, both containing 17 - 18% chromium, 10 - 14% nickel, and 2 - 3% molybdenum. These elements contribute to their excellent corrosion resistance and oxidation resistance.

The difference lies in the lower carbon content of 316L stainless steel compared to 316 stainless steel. The carbon content in 316L stainless steel is typically below 0.03%, while in 316 stainless steel, it is usually around 0.08%. Due to its lower carbon content, 316L stainless steel generally exhibits better corrosion resistance than 316 stainless steel, making it particularly suitable for applications in high-temperature and corrosive environments. Therefore, 316L stainless steel is commonly used in the manufacturing of demanding applications such as medical devices, marine equipment, and food processing equipment.

It's important to note that although 316L stainless steel coil offers improved corrosion resistance, its lower carbon content may result in lower strength and wear resistance. In specific applications, it's necessary to consider the performance characteristics of both 316 and 316L stainless steel, taking into account the specific environment and requirements, to select the appropriate material.

Stainless Steel 200 / 300 / 400 Series Characteristics

Stainless steel coil is typically composed of iron, carbon, chromium, nickel, cobalt, and other alloying elements. Stainless steel can be divided into three series: 200 series, 300 series, and 400 series, which differ in the type and proportion of alloying elements.

200 Series: Primarily containing nickel and manganese but no chromium, they have poorer corrosion resistance but good ductility and formability, making them easy to process and shape. Products made from 200 series stainless steel include kitchen utensils, furniture, pipes, and building structures.

300 Series: Primarily containing chromium and nickel but no molybdenum, they have excellent corrosion resistance and high-temperature performance, making them particularly suitable for use in industries such as chemical, petroleum, and food processing. The most common of these is 304 stainless steel, which has a wide range of applications including kitchen utensils, food processing equipment, medical devices, building exterior decoration, and more.

400 Series: Primarily containing chromium and molybdenum but no nickel, they have poorer corrosion resistance but good heat and wear resistance, making them particularly suitable for use in industries such as mechanical and automotive manufacturing. The most common of these is 430 stainless steel, which is used to make components such as cutting tools, screws, bearings, and automotive parts, as well as building and decorative materials.

Stainless Steel Surface Finish

NO.1 Surface: Hot-rolled, annealed, and pickled surface with a rough texture, suitable for industrial applications that require heat and corrosion resistance.

2B Surface: Cold-rolled, annealed, and pickled surface with a matte finish, processed to make the surface smooth, and easily polished for a brighter appearance.

BA Surface (Bright Annealed): Cold-rolled, annealed, and bright annealed surface with excellent glossiness and high reflectivity.

NO.4 Surface: Also known as a brushed finish, this surface is achieved by using a 150-180 grit abrasive, resulting in a continuous and unidirectional pattern of fine lines.

HL Surface (Hair Line): Hairline finish, achieved by using an appropriate grit size of abrasive to create continuous linear patterns that resemble hairlines.

NO.8 Surface (Mirror): Mirror-like finish achieved by cold-rolling and then polishing to a high shine.

Checkered Plate: Stainless steel plate with a balanced three-dimensional pattern used for anti-slip purposes.
