Types, Characteristics and Applications of Steel Plate Processing
Steel materials are sold in both the form of parts such as bolts and nails, and in the form of processed materials such as pipes, bars and blocks. Sheets are also sold as a form of material, usually called iron sheets or steel sheets, and are used in industrial products and construction sites, etc.
Five Common Types of Steel Plates
Steel plates in general circulation can be classified into several types based on their manufacturing methods and subsequent treatments. This article will introduce five main types used in industrial products and construction sites.
SPHC (SPH) hot-rolled steel plate
This material is also simply referred to as HOT or black-coated steel. It is a material that is rolled at a temperature range of 900°C to 1200°C. Its surface is covered with a layer of black oxide film (also known as oxide scale). This material has a wide application range and is suitable for bending and deep drawing processes.
The uses, types and characteristics of rolled steel plates: SPHC (hot-rolled steel plates), SPCC (cold-rolled steel plates)
SPHC-P (SPHC) hot-rolled steel plate
Also known as acid-washed steel plate, it is a material obtained by removing the oxide film on the surface of hot-rolled steel plate through the acid-washing process. When referring to SPHC, it can either mean black-baked steel or acid-washed steel. Therefore, when specifying the material, it is necessary to pay attention to whether it has "P" or has undergone acid washing. Its properties are the same as those of black-baked steel and it is mostly used in processing techniques such as stamping.
SPCC cold-rolled steel plate
Also known as rolled material, cold-rolled material, or smooth sheet, it is produced by further cold rolling of hot-rolled steel plates. Its surface is smooth and shiny; it is soft and has excellent machinability. Due to the absence of an oxide film on its surface, it is very prone to rusting. During circulation and processing, it needs to be coated with oil for protection. When used as a product, rust prevention treatments such as spraying need to be carried out before and after processing.
SECC electro-galvanized steel sheet
Also known as galvanized steel sheet, it is a cold-rolled steel sheet that has undergone electro-galvanizing treatment. It is one of the most widely used materials in surface-treated steel sheets. The galvanizing process gives it excellent rust-proof properties and a beautiful, shiny appearance. Additionally, it is easy to process and has excellent decorative properties, and is often used for cover plates of mechanical components, etc.
The uses, types and characteristics of galvanized steel plates: SECC (electro-galvanized steel plate), SGCC (hot-galvanized steel plate)
SGCC hot-galvanized steel plate
This type of steel plate is also commonly referred to as iron sheet. It is a cold-rolled steel plate that has undergone hot-dip galvanizing treatment. Due to its thicker coating, it has higher corrosion resistance than electro-galvanized steel and is therefore often used in outdoor building materials and other applications.
SPTE (SPHC) electroplated steel plate
This is a type of steel plate called tinplate, which is a cold-rolled steel plate that has been electroplated with tin. It has a soft texture and is easy to process. It also has the advantage of being easy to weld (due to the low melting point of the tin on the surface). It is often used to manufacture containers for beverages or paints, among other things.
