The mechanical property of JIS G4051 S45C steel

Grade	Availability hardness	Tensile strength min	Yield strength min	Elongation % min(δ5)	impact strength	hardness
S50C	143~187HBS 179~235HBS 212~277HBS	630MPa	375MPa	14%	≥39(4)	≤241HB（without heat treatment） ≤207HB (Annealed Steel)

(3) General use
The S50C steel sheets, S50C steel round bars, S50C steel tubes are usually used to manufacture mechanical and spring pieces with high abrasion resistance and low dynamic load and impact, such as forging gears, pull rods, rollers, shaft, friction disc, agricultural plowshares, heavy loading spindle ,etc.
And S50C machining parts are applied in many aspects which include plastic plates and mechanical parts for mould making, the pads for all kinds of cold working moulds, die retaining plates, standard mould materials, etc.
