S50C steel is high strength medium carbon steel under the standard
JIS G4051. JIS G4051 S50C has low cold-forming plasticity property,
poor welding performance and hardenability, but it has no temper
brittleness and cutting properties is ok. S50C steel is used in
condition of normalizing , quenching or tempering.
1. JIS G4051 S50C steel application:
S50C steel is widely used to manufacture mechanical product and
spring requiring high wear resistance, not big dynamic load and the
impact, such as forging of gear, tie rod, roller, shaft, friction
plate, agricultural dig colter spindle, heavy load, etc.
