C35 vs C75S
Side-by-side chemical composition and mechanical property comparison.
Overview
C35
1.0501
Medium-carbon unalloyed steel with moderate strength. Good machinability and weldability. Used for lightly stressed components like levers, axles, bolts, and general machine parts.
C75S
1.1248
High-carbon spring strip steel — C 0.70-0.80%. Between C67S (0.65-0.72%) and C85S (0.83-0.90%). Good fatigue strength and edge retention. Used for flat springs, leaf springs, saw blades, snap rings, and reed valves. Available as cold-rolled precision strip in hardened & tempered condition (HRC 58-62).
