According to the different coordination metals, it can be divided into several types. Iron is unalloyed. If two pieces of steel with the same size and appearance are attracted by the same magnet, then iron is attracted to a great extent.

Another method is based on the characteristics of the alloy: low melting point, the same two pieces, the weight is iron.

Different materials:

Iron plate: wrought iron pressed into a plate shape.

Steel plate: a flat steel plate cast with molten steel, cooled and pressed.

Extended data:

Steel plates are divided by thickness, and thin steel plates

Steel plates are divided into hot rolling and cold rolling according to rolling.

The width of the plate is 500 ~1500mm; The thickness and width are 600 ~ 3000mm. Plates are divided into ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron plates. According to professional purposes, there are oil drum board, enamel board, bulletproof board and so on. According to the surface coating, there are galvanized sheet, tinned sheet, lead-plated sheet and plastic composite steel sheet.

The steel grade of thick steel plate is basically the same as that of thin steel plate. In all aspects of products, besides bridge steel plate, boiler steel plate, automobile steel plate, pressure vessel steel plate and multi-layer high-pressure vessel steel plate, there are also some kinds of steel plates, such as automobile girder steel plate (2.5~ 10 mm thick), patterned steel plate (2.5~8 mm thick), stainless steel plate and heat-resistant steel plate, which intersect with thin plates.

There is also the material of steel plate. Not all steel plates are the same, the materials are different, and the steel plates are used in different places.
