What Are 304 Stainless Steel Coils?
304 stainless steel, also known as 18-8 stainless steel, is one of the most widely used austenitic stainless steel. It has strong corrosion resistance in harsh environments such as freshwater, seawater, wastewater, acid, and alkali, suitable for the manufacture of deep-drawn parts and acid pipelines, containers, structural parts, various instrument bodies, etc., and can also manufacture non-magnetic and low-temperature equipment and parts. 304 stainless steel coil is a non-magnetic, easy-to-form, easy-to-weld, high-temperature-resistant coil product made of 304 stainless steel after annealing and pickling. It is one of the indispensable materials in life.

304 Stainless Steel Coil Surface Treatment
304 stainless steel coils can be treated with a variety of surface treatments to improve appearance, corrosion resistance, and functionality. The following are some common surface treatment techniques for 304 stainless steel coils:
2B surface treatment: It is one of the most common surface treatment methods, pickling and peeling after cold rolling to obtain a relatively smooth and shiny surface. 2B treatment can provide a certain degree of corrosion resistance and decorative effect and is widely used in stainless steel products.
BA surface treatment: It is a high-brightness surface treatment obtained by annealing and pickling at high temperatures. The surface after BA treatment is bright and smooth, suitable for applications requiring high decorativeness.
No.4 Surface treatment: Through mechanical polishing, a surface with a frosted effect is produced. It has a certain decorative effect and scratch resistance and is often used in the fields of construction, furniture, and decoration.
8K mirror finish: It is a high-brightness surface treatment obtained through a multi-pass polishing process. With a very high finish and specular reflection, it is often used in high-end decoration, electronics, and ornamental materials.
Titanium gold surface treatment: a metal texture surface treatment is formed by coating a titanium gold alloy film on the surface of stainless steel. It can give stainless steel more color options and visual effects and is often used in interior decoration, artwork, and other fields.
Different surface treatment techniques may affect the corrosion resistance, decorative effect, and cost of stainless steel coils. Our group has factories, warehouses, advanced production equipment, and complete production lines, which can provide you with one-stop high-quality coil products and the best service, combined with your application needs and budget, to help you provide the most professional Solutions, and the most suitable steel coil products.
What Are the Advantages of 304 Stainless Steel?
Among the 300 series stainless steel coils, 304 stainless steel coils are more resistant to high temperatures, have excellent processing performance and better toughness, and have stronger rust resistance than 200 series stainless steel coils. Its specific advantages are:
- Good corrosion resistance: 304 stainless steel coil contains 18% chromium and 8% nickel, which makes it have excellent resistance in common corrosive media. Compared with other 300 series stainless steel coils, the corrosion resistance of 304 stainless steel coils is more extensive and comprehensive.
- Excellent heat resistance: 304 stainless steel coils can still maintain their structural stability and strength in high-temperature environments and can withstand short-term heating up to 870 degrees Celsius, showing good high-temperature resistance.
- Good processing performance: 304 stainless steel coil has excellent processing performance, and is easy to cut, bend, weld, and cold work and other processing methods. With high plasticity and plasticity, it can meet the manufacturing needs of various complex shapes and sizes.
- High strength: 304 stainless steel coil has high strength and can withstand large mechanical stress and pressure, making it a choice for structural stability and durability, suitable for application scenarios that require high-strength materials.
- Good appearance and decoration: 304 stainless steel coil has a bright surface, showing a modern and high-end appearance, and can be easily polished, sandblasted, and pickled to meet different decoration needs.
304 stainless steel coil has excellent performance and is widely used in many application fields. Its good corrosion resistance, heat resistance, high strength, and beautiful appearance make 304 stainless steel coil the material of choice in many industries.
The Difference between 304 Stainless Steel Coil and 304L Stainless Steel Coil?
304-grade stainless steel and 304L stainless steel are mainly composed of 18% chromium (Cr) and 8% nickel (Ni). The main difference is that 304L stainless steel is a low-carbon 304 steel. After welding or stress relief, 304L stainless steel has excellent crystallization resistance corrosion performance. But because 304 stainless steel coil contains slightly higher carbon content (usually between 0.08% and 0.10%), it has slightly higher hardness and better wear resistance than 304L stainless steel coil. At the same time, 304 stainless steel coils are more suitable for high-temperature environments and can maintain the stability and strength of their structures at high temperatures, and have a slightly stronger adaptability to high-temperature environments.
304 stainless steel coils may be more suitable in some specific applications, such as those that require higher strength and hardness, those that need to resist wear and abrasive effects, and those that require resistance to high-temperature stress and high-temperature corrosion. If your demand is one of the application scenarios of the above aspects, then it is recommended that you choose 304 stainless steel coil, the quality is guaranteed, and this will be your best choice!
