Product Description

S30C S50C hot-rolled steel plate is Japanese standard high-quality carbon steel manufactured by electric furnace, open hearth furnace or pure oxygen converter steelmaking method. The metallographic structure of the steel is uniform and has no structural defects.
S30C S50C hot-rolled steel sheet executive standard: JIS G4051
Delivery state of S30C S50C hot-rolled steel plate: Unless otherwise specified, it is delivered in hot-rolled or forged state; when used as die steel, it is usually delivered in hot-rolled, normalized, normalized and tempered state.
S30C S50C hot-rolled steel plate product performance introduction
(1) High-grade high-quality medium-carbon steel, the steel has a carbon content (mass fraction, %) ≥ 0.4, excellent wear resistance, reduced ductility, easy deformation and cracking after quenching, so quenching is extremely important, and must be quenched after tempering. To avoid temper brittleness.
The cutting performance of this type of carbon steel can be improved by implementing spheroidizing treatment. The steel is usually used after tempering to a hardness of 19~22HRC to increase its cutting performance
(2) Steel plate hardness requirement: 140-260HBW
(3) Steel properties: good machinability and excellent machinability
(4) General purpose of steel: suitable for plastic formwork matching boards and mechanical parts
S30C S50C hot-rolled steel plate application range: S30C S50C hot-rolled steel plate is widely used in aerospace, electric power, petrochemical, shipbuilding, machinery, electronics, environmental protection and other industries.

Zhengde hot-rolled steel coil manufacturers use slabs (mainly continuous casting slabs) as raw materials, and after heating, they are made into strip steel by rough rolling units and finishing rolling units. The hot steel strip coming out of the last rolling mill of finishing rolling is cooled to the set temperature by laminar flow, and rolled into steel strip coils by the coiler. The cooled steel strip coils undergo different finishing operations according to the different needs of users. Line (leveling, straightening, cross-cutting or longitudinal cutting, inspection, weighing, packaging and marking, etc.) are processed.
