Chrome plate coil

Chrome plate also known as tin-free steel sheet, refers to a cold-rolled low-carbon steel sheet or strip coated with metal chromium and chromium oxide on both sides obtained through continuous electroplating of chromium.

Chromium plating is to prevent the surface of the steel sheet from corrosion and extend its service life. Chromium plating is a new type of can and lid material developed under the high cost of metal tin, which can partially replace tinplate. The rolled one is called chrome-plated steel strip, and the one cut into sheets is called chrome-plated steel sheet.

The main purpose of functional chrome plating is to increase the surface hardness of certain parts, improve wear resistance, or add functions according to special needs of the product surface. For example, to prevent light reflection and improve friction conditions, functional chrome plating such as hard chrome plating, milky white chrome plating, loose hole chrome plating and black chrome plating are used.

The structure of chrome-plated sheet coil has four layers: steel substrate, metal chromium layer, hydrated chromium oxide layer and oil film. Due to the same substrate, the mechanical properties are the same as tin-plated sheet, but it has some characteristics in application:

1. The cost is about 10% lower than that of tin-plated sheet, and the appearance gloss is not as good as that of tin-plated sheet.
2. Chrome-plated sheet has strong adhesion, and its adhesion to organic coatings is 3 to 6 times stronger than that of tin-plated sheet. It also has stronger resistance to sulfide corrosion than tin-plated sheet.
3. Chrome-plated sheet cannot be soldered, and can only be overlapped by resistance welding or bonding.
4. The coating is thin and has poor toughness, and it is easy to break when making cans, so it is not suitable for punching cans, but can be used for deep punching cans.
5. Chrome-plated sheet has strong high temperature resistance. Generally, there is no obvious change in color and hardness at 5000 ℃, and it starts to soften at 7000 ℃.

In summary, chrome-plated coil is a metal product with excellent performance. Its wide application field makes it play an important role in various industries. With the continuous development of technology and the continuous change of demand, the varieties and specifications of chrome-plated coil are also constantly enriched and improved, providing more choices for the development of various industries. I believe that with the continuous improvement of technology, chrome-plated coil will have a wider application prospect in the future.

Ordinary chrome-plated coil: Ordinary chrome-plated coil refers to a product that is plated with a layer of chrome on the surface of the steel plate to increase its corrosion resistance and improve its aesthetics. This chrome-plated coil is widely used in furniture, construction, machinery, electrical appliances and other fields.

High-strength steel chrome-plated coil: A chrome layer is plated on the surface of the high-strength steel plate to improve its tensile, compressive and impact resistance, making it suitable for more stringent use environments. This product is usually used in automobile manufacturing, shipbuilding, bridge construction and other fields.

Chrome-plated coil for deep drawing: Chrome-plated coil for deep drawing refers to high-quality chrome-plated coil that is not prone to cracking and oxidation during the stamping process. This product has a smooth surface and excellent forming properties, and is suitable for stamping manufacturing fields such as automobile bodies and home appliance shells.

High-temperature anti-oxidation chrome-plated coil: High-temperature anti-oxidation chrome-plated coil is a chrome layer plated on the surface of the steel plate that can still maintain its surface gloss and anti-oxidation properties under high temperature environments. This product is suitable for use in high-temperature environments such as aerospace, petrochemicals, and boiler manufacturing.

Chrome-plated coils for printing: Chrome-plated coils for printing refer to a layer of chrome plated on the surface of steel plates to improve their surface flatness and anti-corrosion performance. They are suitable for the manufacture of high-grade color printing paper, packaging paper and other printed products in the printing industry.

Chrome-plated coils for medical devices: Chrome-plated coils for medical devices refer to a layer of chrome plated on the surface of steel plates to improve their antibacterial and easy-to-clean performance. They are suitable for surgical instruments, medical equipment and other fields.

Chrome-plated roll is a product made by coating the surface of steel plate with chrome layer. Chrome-plated roll has the characteristics of corrosion resistance, beauty and wear resistance, so it has a wide range of uses in many fields and industries.

First of all, chrome-plated roll is often used in the manufacture of household products. For example, many kitchen utensils and furniture use chrome plate roll as material because of its flat surface, high gloss, not easy to rust and corrode, and easy to clean and maintain.

Secondly, chrome-plated roll is also widely used in the field of automobile manufacturing. Chrome plate roll can not only improve the appearance and texture of the car, but also increase the corrosion resistance and service life of the car.

In addition, chrome-plated roll is also used in the manufacture of building materials. For example, some building appearance decoration materials, such as wall panels, roofing materials and door and window frames, usually use chrome plate roll.

In addition, chrome-plated roll is also widely used in the manufacture of various electrical appliances and electronic products. For example, household appliances such as refrigerators, washing machines, air conditioners, and appearance parts and components of electronic products such as mobile phones and tablets, all use chrome-plated roll.

In short, chrome-plated coils are widely used in household products, automobile manufacturing, building materials manufacturing, and electrical and electronic product manufacturing. It plays an important role in these fields, giving various products good appearance, corrosion resistance and durability.
