Hot Rolled Q235 Q195 Carbon Steel Sheets 3mm 4mm 6mm Cold Rolled Surface

Hot rolled steel is steel that has been roll-pressed at very high temperatures—over 1,700, which is above the re-crystallization temperature for most steels. This makes the steel easier to form, and resulting in products that are easier to work with. To process hot rolled steel, manufacturers first start with a large, rectangular length of metal, called a billet. The billet is heated and then sent for pre-processing, where it is flattened into a large roll. From there, it is kept at a high temperature and run through a series of rollers to achieve its finished dimensions. Steel shrinks slightly as it cools. Since hot rolled steel is cooled after processing, there is less control over its final shape, making it less suitable for precision applications. Hot rolled steel is often used in applications where minutely specific dimensions aren't crucial.Hot-rolled steel and sheet metal products are commonly used for industrial applications worldwide. With a wide range of options, HR plate and sheet metal products provide numerous advantages that other metal products cannot replicate.

Steel Sheet Speification:

Carbon steel manufacturing process:

The smelting of carbon steel is usually carried out in converter and open hearth. Converters generally smelt ordinary carbon steel, while open furnaces smelt all kinds of high-quality steel. The technology of oxygen top blow converter is developing rapidly and it can replace open hearth furnace. The refined liquid steel is injected into the ingot mold to obtain various ingot. After the ingot is forged or rolled, it is processed into plates, strips, bars, and sections of various sectional shapes. Carbon steel is usually used directly in the hot rolled state. When used for manufacturing tools and various machine parts, it needs to be heat treated according to the requirements of use; As for steel castings, most of them are heat-treated.

Steel Sheet Application :

1. Construction field: Carbon steel plates are often used in the manufacture of building structures, such as steel frames, steel beams, etc. Due to the high strength and plasticity of carbon steel plate, it can withstand large loads, so the widely used in construction.

2. Automobile manufacturing: carbon steel plate is an important material for manufacturing automobile body and frame. carbon steel tool It has good plasticity and welding performance, which can meet the requirements of automobile manufacturing.

3. Home appliance manufacturing: Carbon steel plates are often used in the manufacture of home appliances, such as refrigerators and washing machines.The carbon steel plate can be made into parts of different shapes through the stamping process to meet the needs of home appliances need.

4. Shipbuilding: Carbon steel plates are also widely used in shipbuilding. Due to the carbon steel tool Good plasticity and welding performance can meet the requirements of ship structure.

5. In other fields, carbon steel plates are also widely used in machinery manufacturing, petrochemical, metallurgy and other fields. area.

Steel Sheet Characteristic:

1. High strength: carbon steel plate has high strength, which can meet the needs of various structures. which is high Carbon steel plate has the highest strength, but poor toughness, and is suitable for occasions requiring high strength.

2. Good plasticity: carbon steel plate has good plasticity, and can be processed by cold processing and hot processing Forming and processing in different ways to meet the needs of different shapes.

3. Good welding performance: carbon steel plate is easy to weld, and multiple carbon steel plates can be welded by welding process The steel plates are joined to form structures of larger dimensions.

4. Poor corrosion resistance: carbon steel plates are prone to rust in humid environments and require anti-corrosion treatment management to prolong the service life
