Stainless Steel 304L Features and Applications

304L stainless steel custom-size precision blank is a commonly used stainless steel alloy, consisting of 18% chromium, 8% nickel, and small amounts of carbon, manganese, phosphorus, sulfur, and other elements. Its chemical composition gives it excellent corrosion resistance, high-temperature resistance, good formability, weldability, and deep-drawing properties, making it widely used in the industrial sector.

304L stainless steel is the low-carbon version of stainless steel 304. Compared to 304, 304L has a lower carbon content, resulting in improved corrosion resistance and weldability. Specifically, 304L offers the following advantages:

Improved Corrosion Resistance: Due to its low carbon content, 304L exhibits better corrosion resistance, especially during welding. It is commonly used in applications that require high corrosion resistance, such as chemical, pharmaceutical, and food processing industries.

Enhanced Weldability: The low carbon content of 304L makes it easier to weld and reduces the risk of intergranular corrosion after welding. It is often used in applications that require welding, such as pipelines, storage tanks, and other containers.

Overall, 304Lstainless steel custom-size precision blank finds wide application in industries that require high corrosion resistance and weldability, including pharmaceuticals, food processing, chemical, oil and gas extraction, and marine engineering.

Stainless Steel 200 / 300 / 400 Series Characteristics

Stainless steel custom-size precision blank 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.
