Classification introduction of steel plates
As an expert in the field of pipeline systems, Haihao Group widely uses steel plates in daily production and orders various types of steel plates for customers. Here we will introduce the different classifications and broad application areas of steel plates.
Common steel plate materials
The main materials of steel plates include ordinary carbon steel, stainless steel, high-speed steel, high manganese steel, etc. They are materials made by pouring molten steel, cooling and mechanically pressing it. Most steel plates are flat or rectangular and can be processed by mechanical pressing or cutting from wide steel strips.
ASTM A860 and A105N steel plates
Classification of steel plates
Classified by thickness:
Thin plate: thickness < 4mm
Middle plate: 4mm~20mm
Thick plate: 20mm~60mm
Extra thick plate: 60mm~115mm
Classification by production method:
Hot rolled steel plate: There is oxide scale on the surface, suitable for processing, low hardness and good ductility.
Cold-rolled steel plate: No oxide scale on the surface, good quality, high hardness, relatively difficult to process but high strength.
Classification by surface features:
Galvanized sheet (hot-dip galvanized sheet, electro-galvanized sheet): anti-corrosion coating, including hot dip method and electroplating method.
Tin plate: Cold-rolled thin steel plate, plated with thin metal tin on both sides, used for food cans, electronic devices, etc.
Composite steel plate: metal composite steel plate and non-metal composite steel plate, including metal cladding and viscoelastic resin composite plate.
Color-coated steel plate (color-coated steel plate): The surface has been treated and is widely used in construction, home appliances, automobiles and other fields.
Classified by use:
bridge steel plate
boiler steel plate
shipbuilding steel plate
Armor steel plate
Automobile steel plate
roof steel plate
Structural steel plates: used for mechanical parts and engineering structures, including carburized steel, quenched and tempered steel, spring steel, etc.
