Q235 is cold rolled silicon steel? What kind of steel is cold-rolled silicon steel in the end?
Mainly used in the manufacture of surface quality requirements are not high, and do not need deep drawing processing products, such as ventilation pipes, mechanical enclosures, switch boxes, file cabinets, etc., are also commonly used as welded pipe and cold formed steel billet. Widely used in various industrial sectors.
Comply with GB700-88 regulations and GB700-79 (general carbon structural steel technical requirements) regulations.Cold rolled silicon steel sheet, also known as Cold-rolled electrical steel strip, is made of silicon containing 0.8%-4.8% silicon steel as the material, by cold rolling.There are two kinds of steel strip with no grain orientation and grain orientation in cold rolled silicon steel sheet. The cold rolled electrical steel strip has the characteristics of smooth surface, uniform thickness, high stacking coefficient, good punching quality, etc., and the magnetic sense is higher and the iron loss is lower than that of the hot-rolled electric steel band. Instead of producing hot rolled motor or transformer with cold strip, its weight and volume can be reduced by 0%-25%. If the cold rolled oriented belt, better performance, use it instead of hot-rolled or cold-rolled low grade, can reduce the power consumption of the transformer 45%-50% transformer, and more reliable performance.
Conforms to the GB700-88 carbon structural steel chemical composition stipulation and GB700-79 (ordinary carbon structural steel technical specification) stipulation.
Q235- hot-rolled plain sheet steel (GB912-89, GB708-88)Ordinary hot-rolled sheet metal plate surface commonly known as the black, because black clouds were named.
