60 vs 1060
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.
60
Carbon Steel
60 is the highest-carbon GB/T 699 machinery grade in common trade (AISI 1060 class), used where plain-carbon spring and wear performance is enough.
Standards: DIN 1.0601 (C60) · AISI 1060 · JIS S58C (near) · GB 60 (GB/T 699)
1060
Carbon Steel
1060 is a high carbon steel for springs, wear parts and tools of moderate duty. It hardens reliably in small sections and is one of the most common spring steels in general engineering.
