ST14 steel is German brand. It is cold rolled steel. ST14 steel the yield strength of common structural steel in Germany is 210. ST14: C<0.08, Mn<0.40, P<0.020, S<0.030, Al>0.025. ST12 is the common cold rolled steel, cold rolled steel stamping grade
ST13, ST14 is ST15 grade ultra low carbon deep drawing deep drawing is ST16 grade ultra deep ultra low carbon. ST12 is equivalent to DC01, SPCC, ST13 equals DC03, SPCD, ST14 equals DC04, SPCE, 08AL, ST15 equals DC05, SPCF, and ST16 equals DC06, SPCE-T. ST14 steel tensile strength: 270~370.ST14 steel elongation (%):32.0.ST14 steel hardness: < = 57 HRB. Compared with ordinary low carbon galvanized sheet, it has higher hardness, but worse plasticity and toughness.
Made from cold-rolled ST14 carbon structural steel or ST14 low-alloy structural steel. The surface quality of ST14 cold rolled plate is better. ST14 high quality cold-rolled steel sheet: includes a variety of ST14 high quality steel sheet, is the most commonly used ST14 carbon steel structure, especially ST14 deep drawing with ST14 cold rolled steel sheet, sheet is composed of ST14 low carbon steel ST14 cold rolled steel plate quality, according to the surface quality are divided into three groups; I, II and III, respectively in particular, senior , high surface finish, according to the drawing level is divided into ZF, HF, F (representative for punching drawing is most complex, very complex, complex parts), according to the allowable deviation of the thickness of the steel plate, and is divided into A, B two grade precision, widely used for car tractor industry. ST14 cold rolled steel sheet, with a smooth surface and excellent processing, is used in household appliances such as automobiles, refrigerators, washing machines, as well as industrial equipment and various building materials. ST14 cold rolled plate has a good performance, which can be obtained by cold rolling, thinner and higher precision of ST14 cold strip steel and ST14 steel, high flatness, high surface smoothness, ST14 cold rolled plate surface clean, easy coating processing, variety, wide use, at the same time with high performance and stamping aging, low yield point features, so ST14 cold rolled plate out a wide range of uses, mainly used in automobile, construction, building materials, printing drum, bicycles and other industries, the best material is also the production of organic coating steel plate. ST14 cold rolling is rolled and rolled on the basis of hot rolled coils. Generally it is the process of hot rolling
