Frequently Asked Questions
SAE 1020 / AISI 1020 (UNS G10200) corresponds most closely to Indian standard C20 or IS 2062 for structural applications, though exact cross-referencing depends on the specific mechanical property requirement. Confirm with your engineering team or our sales team for the precise equivalent for your application.
SAE 1020 contains 0.17-0.23% Carbon, 0.30-0.60% Manganese, max 0.040% Phosphorus, and max 0.050% Sulphur, with the balance iron. See the full chemical composition table above.
Yes. Due to its low carbon content, SAE 1020 is well suited to case hardening (carburizing), which is why it's commonly used for shafts, gears, and other components needing a hard wearing surface with a tough core. Its low carbon content does make it resistant to induction and flame hardening, however.
