Forged SAE1050 / S50C High Carbon Tool Steel Plate Thickness 10-350mm
Similar grade: DIN-1.1210, AISI-SAE1050, JIS-S50C, GB-50#
Performance introduction:
• 1, Grade S50C carbon steel is a high quality medium carbon steel,which adopted by the furnace, open-hearth, or oxygen converter steelmaking manufacture full killed steel having a uniform microstructure features.
• 2, The carbon composition of this kind of steels is over 0.4%, and it has good wear resistance, High tensile strength,easy for deformation and crack when Quenching,so that quenching for this material is very importance and it must quick cooling after tempering in order to avoid temper brittleness.
