Description: S45C is a kind of high carbon steel grade which based on the standard of JIS G 4051- 2009. S45C steel has excellent weldability and machinability, and it can be subjected to various heat treatments. S45C is suitable for shafts studs, keys. Equivalent Grades: GB/JB 45# DIN 1.0503 AFNOR CC45 NF C45 UNI C45 NBN C45-1 SS 1650 UNE F.114 AISI/SAE 1045 ISO C45E4 BS IC45/080A47。 Delivery condition: hot rolled or forged + normalizing + Tempering + Quenching and tempering + Normalizing and tempering + Annealing . Chemical composition: GRADE C Si Mn P S Cr Cu Ni S45C 0.42-0.48 0.15-0.35 0.60-0.90 ≤0.03 ≤0.035 ≤0.2 ≤0.30 ≤0.03 Physical properties: GRADE Tensile Strength Yield Strength Elongation contraction impact strength Hardness σb/MPa σs/MPa δ5/% ψ/% J/cm2 HB S45C ≥686 ≥490 ≥17 ≥45 ≥78 201-269 Heat treatment: quenching temperature 820 ℃ ~ 870 ℃, water-cooled, tempering temperature 550 ~ 650 ℃, Application: Widely used in machinery manufacturing, this grade has good mechanical properties. But this is a medium carbon steel, Quenching performance is not good, this grade can be quenched to HRC42 ~ 46. if need a good surface hardness, and also need superior mechanical properties, usually do surface carburizing, so this can get the required surface hardness.
