Introduction of S50C Japanese standard steel plate grade
S50C steel plate is made of electric furnace, open-hearth furnace or pure oxygen converter steelmaking method of Japanese standard excellent carbon steel, the steel metallographic structure is uniform, no organizational defects, the grade steel plate implementation standard is JIS G4051, except for special requirements, in hot rolled or forging state delivery; When used as a die steel, it is usually delivered in hot-rolled, normalized, normalized and tempered condition

S50C steel product performance introduction
(1) high-grade high-quality medium carbon steel, the steel carbon content (mass fraction, %)≥ 0.4, excellent wear resistance, reduced ductility, quenching easy to deform and crack, so quenching is extremely important, after cutting tempering must be quenched to avoid tempering brittleness. The cutting properties of these carbon steels can be improved by spheroidization. The steel is usually tempered to a hardness of 19~22HRC to increase its cutting performance (2) Steel plate hardness requirements: 140-260HBW
(3) Steel characteristics
are good, machinability and machinability are excellent
(4) The general purpose
of steel is suitable for plastic mold base and mechanical accessories
