What is Stainless Steel Coil?
Stainless steel coils are products made from stainless steel through processes such as rolling and hot rolling. Stainless steel sheets typically have a thickness ranging from 0.3mm to 6mm and are widely used in numerous industries including machinery manufacturing, automobile manufacturing, shipbuilding, construction, and medical device manufacturing.
Stainless steel coils are corrosion-resistant, heat-resistant, and durable, making them popular in harsh environments. Additionally, stainless steel sheets are easy to bend, cut, and weld, simplifying and adding flexibility to product manufacturing. Moreover, stainless steel coils can be painted or coated with colored films to present various colors, so they are often used in producing decorative products such as wall panels, roof panels, windows, and doors.
Concept of Stainless Steel Plates
Stainless steel plates are materials made from stainless steel alloys, featuring high strength and good corrosion resistance. They are produced into thin plates of different thicknesses through cold rolling processes, with thicknesses ranging from a few millimeters to several centimeters depending on application needs.
Stainless steel plates usually have a flat and smooth surface and are widely used in many industries such as automobile manufacturing, machinery, household appliances, medical equipment, and food and beverage.
Stainless steel plates boast numerous outstanding advantages including corrosion resistance, high-temperature resistance, easy cleaning and maintenance, durability, and immunity to surrounding environmental impacts. Thanks to these advantages, they are widely used in many fields and regarded as one of the most important metal materials in modern society.
Concept of Stainless Steel Coils
Stainless steel coils are a type of stainless steel plate but with a thinner thickness, approximately 0.3-12mm, so they can be rolled up for easy transportation. There are many types of stainless steel coils, such as 201, 304, 316, and 430 stainless steel coils.
A roll of stainless steel coil usually weighs 5 tons. When purchasing stainless steel plates for multiple uses, people often choose the coiled form, which is then unrolled and cut into plates of different sizes according to needs.
Stainless steel coils are widely used in various industries. For example, in the pipe manufacturing industry, they are used to produce stainless steel pipes; in the cable manufacturing industry, they are used to produce high-wear-resistant cables.
Popular Types of Stainless Steel Coils Today
Currently, there are many types of stainless steel coils used in industry, such as 316, 201, and 430 stainless steel coils, among which 304 stainless steel coils are the most popular. Here is some information about popular types of stainless steel plates:
-
304 Stainless Steel Coils
304 stainless steel coils are one of the most popular types currently. They are made from stainless steel alloys containing approximately 18% Cr and 8% Ni, featuring durable and stable performance, easy processability, and high corrosion resistance.
They are widely used in many different industries such as medical equipment manufacturing, household appliances, home appliance manufacturing, glass equipment, water pipes, ships, vehicles, machinery, and other consumer products.
-
316 Stainless Steel Coils
316 stainless steel coils are made from alloys containing about 16-18% Cr, 10-14% Ni, and 2-3% molybdenum. Due to the higher molybdenum content than 304 stainless steel, 316 stainless steel has better corrosion resistance in environments containing salt and acid.
They are often used in industries such as pharmaceuticals, food, chemicals, energy, nuclear energy, mechanical engineering, and building materials. They are the preferred material for high-corrosion-resistance applications such as pipes, storage tanks, and ships.
-
201 Stainless Steel Coils
201 stainless steel coils are one of the popular types currently. They are made from a stainless steel alloy containing about 17% chromium and 4.5-6% nickel, and sometimes other elements like copper, manganese, or nitrogen are added to enhance product performance.
The performance of 201 stainless steel coils is similar to that of 304 stainless steel coils but with a usually lower price. They are often used in aesthetic decoration applications, household appliance manufacturing, home product manufacturing, and other consumer products.
They have relatively high hardness and strength, heat resistance, and basic corrosion resistance, making them widely used in applications such as manufacturing stoves, ovens, air ducts, chemical tanks, components in the food and medical industries, automobile parts, and many others.
How to Distinguish Between Type 1 and Type 2 Stainless Steel Coils
Currently, there are two types of stainless steel coils on the market: Type 1 and Type 2. Customers should know how to distinguish them to avoid buying products with incorrect prices or that do not meet their needs. Let’s learn about these two types!
- Type 1 Stainless Steel Coils
Grade 1 stainless steel coils are the highest quality materials in stainless steel industry terminology. They have a higher alloy content, with chromium ranging from 18% to 20%, which makes them harder. Therefore, Grade 1 stainless steel plates also have better corrosion resistance.
In addition, Grade 1 stainless steel plates are usually produced and evaluated according to strict quality standards to ensure the best quality and durability. They are generally bright and smooth because they undergo more advanced refining and polishing methods.
The above standards confirm the value of Grade 1 stainless steel plates in the current market, and their price is higher than that of Grade 2 stainless steel coils.
- Type 2 Stainless Steel Coils
Grade 2 stainless steel plates and coils are a term in the stainless steel industry referring to those with lower manufacturing and rating quality standards than Grade 1.
Type 2 stainless steel coils have a lower alloy content than Type 1, containing only about 16-18% chromium, so they have lower strength, toughness, and corrosion resistance compared to Type 1.
Moreover, the production and evaluation quality standards of Grade 2 stainless steel coils are lower than those of Grade 1, resulting in lower color luster and a less smooth surface.
Applications of Stainless Steel Coils in Industrial and Civil Fields
Stainless steel coils are materials made from stainless steel, featuring corrosion resistance and high-temperature resistance, and are widely used in industrial and civil fields. Here are some common applications:
- Food and medical industries: Stainless steel coils are used to manufacture medical equipment, food containers, workbenches, and refrigerators in food and medical factories. The corrosion resistance and easy cleaning properties of stainless steel are the main reasons for their selection in these industries.
- Machinery manufacturing industry: They are used to manufacture transmission components, engine parts, and other mechanical parts.
- Construction industry: They are used to manufacture pipe system components, door and window parts, and other housing components.
- Electronics industry: They are used to manufacture components in electronic devices such as microcircuits, chips, and other parts.
- Petroleum and natural gas industry: They are used to manufacture parts of pressure equipment such as pipes and mechanical parts in the petroleum and natural gas industry.
How much do stainless steel coils cost?
The price of stainless steel coils depends on various factors such as the type of stainless steel, size, thickness, exchange rates, and market conditions. Generally, the price ranges from 9 CNY to 30 CNY per kilogram. OrinoxSteel provides the following reference price list:
