Which kinds of sheet steel are divided?
The material of steel plate: It is a flat steel material which is poured with molten steel and pressed and cooled. It is flat and rectangular and can be rolled directly or cut from a wide steel strip.
The steel plate is divided into thicknesses, thin steel plates <4 mm (thinnest 0.2 mm), medium-thick steel plates 4 to 60 mm, and extra-thick steel plates 60 to 115 mm.
1, ordinary medium and thick steel plate
Ordinary medium and thick steel plates are deoxidized steel materials. The molten steel of this steel has a relatively high oxygen content, and a large amount of gas is generated during the production process to boil the molten steel, so it is also called boiling steel.
Advantages: The surface of this steel plate is smooth, the quality is very good, and it is easy to process. Because this steel plate does not have concentrated shrinkage cavities, the amount of deoxidizer is small and the price is lower than other steel plates.
Disadvantages: This steel has a large internal gas content, many impurities, is not good for welding and has a lower bearing capacity than other steel plates, so it is not suitable for use as a component that needs to withstand gravity.
2, carbon steel calming steel plate
The carbon steel calming steel plate deoxidizes the molten steel before the production. When the molten steel is poured into the steel ingot, the reaction is relatively calm and there is no boiling state.
Advantages: There is no gas in this steel plate, the impurities are relatively small, the force is very uniform, and the welding performance is good. Widely used for demanding parts
Disadvantages: The surface quality of this steel plate is not as good as the boiling plate, and there are concentrated shrinkage holes, which are more expensive.
3. Low alloy structural steel plate
Low-alloy structural steel sheets are mainly used in the fields of mechanical manufacturing and metal structural components.
Advantages: The performance of this steel plate is superior and the weight is relatively light.
Disadvantages: This steel plate is a calming plate, so the price will be more expensive.
