The EN 10130 standard include DC01, DC03, DC04 etc. The standard of DIN 1623 available grades have ST12, US113, RRST13 and ST14.

Automobile girder steel is a kind of low alloy hot-rolled steel plate with thickness of 2.5-12.0 mm for manufacturing automobile girder (longitudinal beam and cross beam). Due to the complex shape of automobile girder, good stamping performance is required in addition to high strength and cold bending performance for automobile girder steel. The S315MC pickled steel coil, medium thick and heavy steel plates are mainly used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on.

The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, S315MC pickled steel coil. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.
