We offer a customized 304 stainless steel coil service that allows clients to tailor the coil's weight and thickness to their specific requirements. This customization enhances the versatility and application of our products significantly. Our edge trimming services ensure a precise and clean finish, which is crucial for both aesthetics and functionality. Specializing in HL and NO.4 finishes, our coils undergo a meticulous wet sanding process, resulting in surfaces that are smooth, clean, and uniformly finished. We further enhance the quality of these finishes by offering double-sided sanding, ensuring consistency and excellence on both sides of the coil. Additionally, our Bright Annealed (BA) and No.8 Mirror finishes are also available with double-sided processing. This ensures that both sides of the coil achieve the same high standards of reflectivity and smoothness, providing a superior finish that meets the most stringent quality requirements.


In addition to our finishing services, we provide a range of protective coatings and printing options, including PE blue film, PVC black/white film, CO2 laser film, fiber laser film, and material inkjet printing. These services are designed to add a professional and personalized touch to your products, offering added value and brand distinction in the marketplace.

Our commitment to quality and customer satisfaction is reflected in our use of galvanized steel in our export packaging solutions. This choice not only protects the stainless steel coils during transportation but also underscores our dedication to delivering products in their best condition. The robustness and corrosion resistance of galvanized steel make it an ideal packaging material, ensuring that our high-quality coils reach you safely, regardless of the destination.

Our expertise extends beyond manufacturing to serving industries with rigorous standards, such as the chemical industry. Our 304 stainless steel coils are widely recognized for their reliability and performance in challenging environments, making us a trusted supplier for companies within this sector and beyond. Our customers, hailing from various countries and regions, have consistently praised our products for their exceptional quality and durability.

As your high-quality supplier of 304 stainless steel coils, HE-TIEN is committed not only to meeting but also to exceeding your expectations. Our collaboration with industries like the chemical sector and our innovative packaging solutions highlight our dedication to excellence and customer satisfaction. We eagerly anticipate partnering with you to create added value for your business and to support your success in the global market.

Stainless Steel 304 Features and Applications

Stainless steel coil 304 is a commonly used stainless steel alloy composed 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 workability, forgeability, and deep drawability, making it widely used in various industries.

Stainless steel coil 304 exhibits good corrosion resistance, able to withstand corrosive media, including strong acids, alkalis, and saltwater. It also has good high-temperature resistance, maintaining its mechanical and oxidation resistance properties at elevated temperatures. Additionally, stainless steel coil 304 has good workability and can be processed through welding, forging, rolling, deep drawing, and other methods to create complex-shaped parts and products.

Stainless steel coil 304 finds widespread applications in various fields, including food processing, medical devices, chemical industry, construction, automotive, and aerospace:

1. In the food and medical device manufacturing, stainless steel 304 is widely used for its non-toxicity, lead-free nature, corrosion resistance, and ease of cleaning, making it suitable for producing various containers, pipes, instruments, etc.

2. In the chemical industry, stainless steel 304 is commonly used for making pipes, tanks, containers, and other chemical equipment.

3. In the construction industry, stainless steel 304 is employed for fabricating various decorative items, sinks, handrails, doors, and windows.

4. In the automotive and aerospace industries, stainless steel 304 is utilized for its lightweight, high strength, corrosion resistance, and high-temperature performance, making it suitable for manufacturing vehicle bodies, engine components, exhaust systems, and more.

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 coil 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.
