The deep drawing performance of DC01, DC02, DC03 and DC04 is different. DC is DIN 1623-1 flat steel products of low carbon steel cold rolled strip and thin steel plate meaning; DC is DIN 1623-1 . 01, 02, 03, 04 indicate different deep drawing performance levels, and the larger the number, the better the performance.Cold-rolled steel is steel produced by cold rolling, and compared with hot-pressed steel, the thickness will be more accurate, and the surface is more smooth and more beautiful.

Cold-rolled sheet is a product obtained from hot-rolled sheet by cold pressure processing. The surface quality of the cold rolled sheet is superior to that of the hot rolled sheet, and good mechanical properties can be obtained after heat treatment. According to the different needs of production enterprises, cold rolled plate is usually divided into: general cold rolled plate, stamping grade cold rolled plate, deep drawing, extra deep) medium and super deep intermediate cold rolled plate, generally delivered by coil and plate.

Cold rolled steel is the steel produced by cold rolling, under certain conditions, the steel plate can be further pressed into the required thickness, it and hot pressed steel plate compared, the thickness will be more accurate, and the surface is more smooth and more beautiful. At the same time, it also maintains stable performance, such as processing skills are very good, but they are not suitable for processing, so they need to be handed over to customers by annealing.

In the grade of Japanese steel (JIS series), ordinary structural steel is mainly composed of three parts: the first part indicates the material, the second part indicates different shapes, types, uses, and the third part indicates the characteristic number, which is generally the lowest tensile strength. For example: SS400 - the first S means Steel, the second S means "Structure" (Structure), 400 tensile strength lower limit of 400MPa The same way SS330 means tensile strength of 330MPa

Hot rolled steel plate has low hardness, easy processing and good ductility. The surface quality of the hot-rolled steel plate is almost (with low oxidation finish), but the plasticity is good, generally medium and thick plate, cold rolled plate, high strength, high hardness, high surface finish, generally thin plate, can be used as a stamping plate.

#10 steel has a carbon content of 0.1%. The carbon content of #20 steel is 0.2%, and No. 20 steel is commonly used steel. #10 steel will be more reliable than #20 steel when expanding and less prone to cracking. However, in the design,#10 steel will be more expensive than #20 steel, because its allowable stress will be smaller #10 steel pipe weldability is better.

P235GH is a high temperature performance of non-alloy quality steel, the implementation standard :EN10028-2, number :1.0345, with good plasticity, toughness, cold bending and welding properties.
P355GH belongs to the steel plate for medium pressure boiler. It is a kind of steel plate for European pressure vessels, and the implementation standard is EN10028 (European steel plate standard for pressure vessels).
