1055 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.
1055
Carbon Steel
1055 is a high-medium carbon steel for parts needing a hard, wear-resistant surface with a resilient core. It overlaps the lower spring range and is common in agricultural and hand-tool applications.
Standards: DIN 1.0535 (C55) · AISI 1055 · JIS S55C · GB 55
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.
Standards: DIN 1.0601 (C60) · AISI 1060 · JIS S58C (near) · GB 60
