While the carburizing process can be used to case harden most low carbon steels,plain carbon grades such as 1010,1020,A36,etc.should be avoided due to their poor response to oil quenching.For critical components an alloy carburizing grade such as 8620,4820 or 9310 should be used.Case Hardening Steel C 1020,for Construction,Popular Due to its low carbon content,it is resistant to induction hardening or flame hardening.Due to lack of alloying elements,it will not respond to nitriding. C1020 offers better machinability than the normal low carbon commercial alternative of A36.A low carbon,general purpose,special quality machinery steel,suitable for ordinary hammer
