S35C vs 1035
These two grades are listed as equivalents of each other: their chemistry windows overlap and they serve the same applications. They are not always identical — check the differences below before substituting, especially in certified designs.
S35C
Carbon Steel
S35C is the JIS medium-carbon steel matching AISI 1035 / EN C35 — the entry point of the genuinely heat-treatable carbon steels, used for small shafts, bolts and machine parts across Japanese and Asian machinery production.

1035
Carbon Steel
1035 is a medium carbon steel for shafts and forged parts of moderate strength. It heat treats more reliably than 1030 and is a standard grade for studs, bolts and machine components across Asian and European supply chains.
