Mild Steel Sheet Astm A285 Grade C - HR iron plate Hot rolled mild ms steel sheet – Ruigang

Product specification

Thickness: 0.2-300mm

Width: 500-4000mm

The steel plate is a flat steel with a large difference in thickness, width and length.

Steel plate is one of the four major varieties of steel (plate, tube, shape, wire).

Manufacture of steel plate: The steel plate is a flat steel that is cast with molten steel and pressed after cooling.

Product Classification

Steel plates are divided into two types: thin plates and thick plates. Thin steel plate <4 mm (the thinnest 02 mm), thick steel plate 4~60 mm, extra thick steel plate 60~115 mm.

Steel sheets are divided into hot-rolled and cold-rolled according to rolling.

The 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 500-1800mm. In addition to direct delivery after rolling, thin steel sheets are also pickled, galvanized and tinned. According to different uses, the thin steel plate is rolled from billets of different materials and the width of the thin plate is 500~1500 mm; the width of the thick sheet is 600~3000 mm. Sheets are classified according to steel types, including ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel and industrial pure iron sheet, etc.; according to professional use, there are oil drum plates, Enamel plate, bulletproof plate, etc.; According to the surface coating, there are galvanized sheet, tin-plated sheet, lead-plated sheet, plastic composite steel plate, etc.

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 >20mm to 60mm are called thick plates, and steel plates with a thickness of >60mm need to be It is rolled on a special heavy plate mill, so it is called extra heavy plate. The width of thick steel plate is from 1800mm-4000mm. Thick plates are divided into shipbuilding steel plates, bridge steel plates, boiler steel plates, high-pressure vessel steel plates, checkered steel plates, automobile steel plates, armored steel plates and composite steel plates according to their uses. The steel grade of the thick steel plate is generally the same as that of the thin steel plate. In terms of products, in addition to bridge steel plates, boiler steel plates, automobile manufacturing steel plates, pressure vessel steel plates and multi-layer high-pressure vessel steel plates, which are pure thick plates, some varieties of steel plates such as automobile girder steel plates (25~10 mm thick), patterned steel plates, etc. Steel plates (2.5-8 mm thick), stainless steel plates, heat-resistant steel plates and other varieties are intersected with thin plates.

Product Use

Mainly used in the manufacture of bridges, ships, vehicles, boilers, high pressure vessels, oil and gas pipelines, large steel structures. Commonly used materials are ordinary carbon steel, excellent carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel and electrical silicon steel. They are mainly used in automobile industry, aviation industry, enamel industry, electrical industry, machinery industry and other sectors.
