A Guide to Choosing the Right Steel Plate

What is a steel plate?

Steel plate is a flat steel with a large width-to-thickness ratio and surface area. The steel plate is divided into two specifications: thin plate and thick plate, according to the thickness. A thin steel plate is a steel plate with a thickness of 0.2-4mm produced by hot rolling or cold rolling. The width of the thin steel plate is between 500-1400mm.

Classification of steel plates

According to different uses, thin steel plates are rolled from billets of different materials. Commonly used materials are ordinary carbon steel, high-quality carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel and electrical silicon steel. They are mainly used in the automotive industry, aviation industry, enamel industry, electrical industry, machinery industry and other sectors.

In addition to the direct delivery of thin steel plates after rolling, there are also pickling, zinc plating and tin plating. Thick steel plate is a general term for steel plates with a thickness of more than 4mm. In practical work, steel plates with a thickness of less than 20mm are often called medium plates, steel plates with a thickness of more than 20mm to 60mm are called thick plates, and steel plates with a thickness of more than 60mm need to be rolled on a special heavy plate mill, so they are called extra-thick plates.

The width of the thick steel plate is from 0.6mm to 3.0mm. The thick plate is divided into shipbuilding steel plate, bridge steel plate, boiler steel plate, high-pressure vessel steel plate, pattern steel plate, automobile steel plate, armored steel plate and composite steel plate. One branch of the steel plate is the steel strip. The steel strip is actually a very long, thin plate with a relatively small width and is often supplied in coils, also known as strip steel. The steel strip is often produced on a multi-stand continuous rolling mill, and it is the steel strip after cutting into a fixed length, so the productivity is higher than that of a single sheet mechanism.

What is the thickness difference of steel plate?

The thickness difference of the steel plate is that the actual thickness of the steel plate is less than the theoretical thickness, and the difference is generally 0.25 mm or 0.5 mm. That is a thickness of 10 mm steel plate; the actual thickness of only 9.75 or 9.5 is normal.

Why does the steel plate have a drop?

Steel plate is a commodity, so the steel plate will be based on market preferences to determine its thickness.

For example, comparing the steel plate to an apple, the thickness of the steel plate determines the sweetness of the apple, so when the sweet sells well in the market, farmers tend to choose the sweet to plant, and the unsweet will slowly be eliminated. The steel plate manufacturer is the farmer of this planting. After the market baptizes the steel plate, the steel plant stops producing the steel plate, which is not good to sell, and the steel plate with the thickness difference is left.

What is the difference under the steel plate?

The lower difference is generally 0.25mm or 0.5mm; that is, for a steel plate with a thickness of 10mm, the actual thickness is only 9.75 or 9.5 normal.

Is there a steel plate with no drop?

The answer is yes. Generally, buy steel plate thickness of less than 2mm steel plate, the business will clearly tell you is a little thick or a little thick. So 2.75 thick, even 3 mm thick steel plate, 3.5 thick 4 mm thick steel plate in turn analogy.

The calculation formula of steel plate weight:

Weight = L/1000 * W/1000 * T * S

  • L = Length in mm
  • W = Width in mm
  • T = Thickness in mm
  • S = Specific material density (Steel = 7.85)
