Different types of stainless steel coils are divided into different ways

The distinction of stainless steel coils mainly depends on factors such as their chemical composition, hardness, and surface treatment. Here are some common ways to distinguish:

1. Classification by chemical composition

Stainless steel can be divided into different series, such as 200 series, 300 series, and 400 series. Each series has different composition and performance characteristics:

200 series: less nickel content, relatively low price, but low corrosion resistance.

300 series: high nickel content, good corrosion resistance, and is the most commonly used stainless steel series. Typical models include 304, 316, etc.

400 series: low nickel content or even no nickel, usually no nickel, so it has different corrosion resistance and magnetism. Typical models include 409, 430, etc.

2. Classification by hardness and mechanical properties

The hardness and mechanical properties of stainless steel coils can also be distinguished by treatment methods, such as:

Annealed state: improve the ductility and toughness of stainless steel through heat treatment.

Hardened state: increase the hardness and strength of stainless steel through heat treatment, suitable for applications requiring higher strength.

3. Classification by surface treatment

Hot-rolled steel coil: Hot-rolled steel coil is a steel coil produced by hot rolling process, with iron oxide scale on the surface, and has good corrosion resistance.

Cold-rolled steel coil: Cold-rolled steel coil is a steel coil produced by cold rolling process, with a smooth and flat surface, good aesthetics and corrosion resistance.

Galvanized steel coil: Galvanized steel coil is a steel coil with a layer of zinc on the surface, with good corrosion resistance and aesthetics, mainly used in construction, home appliances and other fields.

Color-coated steel coil: Color-coated steel coil is a steel coil with a layer of color coating on the surface, with good decorative performance and corrosion resistance, mainly used in construction, home and other fields.

4. Classification by standards and specifications

The production of stainless steel coils also involves different national and international standards, such as ASTM, AISI, DIN, etc. Each standard has its specific chemical composition, mechanical properties and test methods.

Through the above methods, different types of stainless steel coils can be effectively distinguished and identified. When purchasing or using stainless steel materials, it is very important to understand this basic information, which is directly related to the applicability and performance of the material.

5. Classification by material

Low carbon steel coil: Low carbon steel coil has a lower carbon content and lower strength, but better plasticity and toughness. It is mainly used in construction, manufacturing bolts, nuts, etc.

High carbon steel coil: High carbon steel coil has a higher carbon content and higher strength, but poorer plasticity and toughness. It is mainly used to manufacture tools, knives, etc.

Alloy steel coil: Alloy steel coil is made by adding alloy elements such as manganese, silicon, chromium, etc. to steel to enhance its strength, hardness, corrosion resistance, etc. It is mainly used to manufacture high-strength parts, tools, etc.

6. Classification by use

Structural steel coil: Structural steel coil is mainly used in the manufacture of structures such as buildings, bridges, towers, etc., and requires good strength and plasticity.

Container steel coil: Container steel coil is mainly used to manufacture pressure vessels such as gas storage tanks and reactors, and requires good corrosion resistance and welding performance.

Food grade steel coil: Food grade steel coil is mainly used to manufacture food processing equipment, kitchen utensils, etc., and requires good hygiene and corrosion resistance.

Automotive steel coils: Automotive steel coils are mainly used to manufacture auto bodies, chassis and other parts, and require good strength, plasticity and corrosion resistance.

7. Classification by specifications

Thin plate steel coils: The thickness of thin plate steel coils generally does not exceed 5mm, and they are mainly used to make various instruments, auto bodies, furniture, etc.

Medium plate steel coils: The thickness of medium plate steel coils is generally between 5mm-25mm, and they are mainly used to make various containers, pipelines, bridges, etc.

Thick plate steel coils: The thickness of thick plate steel coils is generally above 25mm, and they are mainly used to make various building structures, vehicle chassis, etc.

When distinguishing different types of steel coils, comprehensive considerations can be made based on their materials, surface treatment, uses, production processes and specifications. At the same time, it should be noted that different types of steel coils also need to take different measures when stored and used to ensure their quality and safety performance.
