4130 Steel Hardening This heat treatment will obtain martensite structure after quenched,it will increase the surface hardness and strength.AISI 4130 steel should be carried out between 870-890, hold suitable time for the steel to be thoroughly heated, then quench in oil, or water.Tempering should be followed immediately after quenched. 4140 High Tensile Steel Interlloy Engineering Steels Hardening:Heat to 840 o C - 875 o C, hold until temperature is uniform throughout the section, soak for 10 - 15 minutes per 25 mm section, and quench in oil, water, or polymer as required.*Temper immediately while still hand warm. Nitriding:4140 hardened and tempered bar can also be successfully nitrided, giving a surface hardness of up to Rc 60. Nitriding is carried out at 490 o C - 530 o C
AISI 4130 steel can be annealed at 843°C (1550°F) followed by air cooling at 482°C (900°F). Tempering of AISI 4130 steel can be performed at 399 to 566°C (750 to 1050°F), depending on the desired strength level. Hardening of AISI 4130 steel can be done with cold working or heat treatment. AISI 4340 Steel - JIS SNCM439 - DIN 1.6563 - Songshun SteelAISI 4340 alloy steel is heat treated at 830°C (1525°F) followed by quenching in oil. Flame or Induction Hardening. As mentioned above, pre-hardened and tempered 4340 steel bars or plates can be further surface hardened by either the flame or induction hardening methods resulting in a case hardness in excess of Rc 50.
