35 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.
35
Carbon Steel
35 is the GB/T 699 equivalent of AISI 1035 / JIS S35C, a medium-carbon machinery steel widely stocked in China as round bar for general shafts and fasteners.
Standards: DIN 1.0501 (C35) · AISI 1035 · JIS S35C · GB 35 (GB/T 699)
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.
