Hot Rolled Carbon Steel Coil A36 Q255 SS400 St37 1000mm-6000mm

1. Ordinary carbon structural steel:

Carbon structural steel is divided into 5 grades according to the yield strength of steel: Q195, Q215, Q235, Q255, Q275. Each brand is divided into A, B, C and D grades due to different quality.

Q195, Q215, Q235 good plasticity, can be rolled into steel plate, steel bar, steel pipe, etc.
Q255, Q275 can be rolled into section steel, steel plate, etc.

2. High-quality carbon structural steel:

steel number is represented by the average mass fraction of carbon content. Such as 20#, 45#, etc. Purpose: Mainly used for manufacturing various machine parts.

3. Carbon tool steel:

Steel number is expressed by the average mass thousandth fraction of carbon content, and is prefixed with T. Such as T9, T12 and so on. Usage: Mainly used for manufacturing various cutting tools, molds, measuring tools, etc.

4. Cast steel:

The cast steel brand is prefixed with ZG before the number. Purpose: Mainly used for manufacturing complex shape and need a certain strength, plasticity and toughness parts, such as gear, coupling, etc.

Hot Rolled Steel is steel that has been roll-pressed at very high temperatures-over 1700, 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.

It is a flat sheet of steel made by pouring molten steel, cooling and pressing. The steel plate is divided according to thickness, the steel plate <4 mm (the thinnest 0.2mm), medium thick steel plate 4-60 mm, extra thick steel plate 60-115 mm. The steel plate is divided into rolling, hot rolling and cold rolling. The width of the sheet is 500~3000 mm; The thick width is 600~3000 mm. There are common steel, high quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet. According to professional use, there are oil barrel board, enamel board, bulletproof board and so on; According to the surface coating layer, galvanized sheet, tin plate, lead plate, plastic composite plate.
