How many types of thick steel plates are there?

1. Ordinary carbon steel boiling steel plate

It is a kind of ordinary carbon structural steel, which is hot-rolled by boiling billets. This kind of steel plate has low carbon content, but has good surface quality and is easy to process. But its core contains more impurities, so the segregation is more serious, and the mechanical properties are not very uniform. The toughness and welding performance of ordinary carbon steel boiling steel plates are not very good, so this steel plate is not suitable for making structural parts that have to withstand impact loads, and welding structural parts under low temperature conditions, but suitable for making stamping parts, and some Too important machine components and parts.

2. Plain carbon steel killed steel plate

It is hot-rolled from killed steel billets. The advantages are good mechanical properties, welding properties, corrosion resistance and plasticity, but the surface quality is not good and the cost is relatively high. Common carbon steel killed steel plates are mainly used to manufacture components, welded parts, and some high-strength structural parts that can withstand impact at low temperatures.

3. Low alloy structural steel plate

It is made of low-alloy structural steel by hot rolling. It has the characteristics of high strength and high performance, and can save raw materials. It is mainly used for mechanical manufacturing and metal structural parts.

4. Weather-resistant steel plate for welding structure

It is to add a small amount of alloying elements such as chromium, nickel, molybdenum, niobium, titanium, zirconium, vanadium to the steel to form a protective layer on the surface of the substrate, which improves the weather resistance and welding performance of the steel. It is mainly used for In the structure of bridges, buildings, etc.

5. Checkered steel plate

On the surface of this steel plate, there are diamond-shaped or lentil-shaped ridges, which are rolled from ordinary carbon structural steel. It has a non-slip effect, so it is commonly used on floors, factory escalators, work frame pedals, ship decks and automobiles. In the bottom plate.
