AISI 4130 Alloy Steel (UNS G41300)
Welding of AISI 4130 steel can be performed by all commercial methods. Heat Treatment - AISI 4130 steel is heated at 871C (1600F) and then quenched in oil. This steel is usually heat-treated at temperatures ranging from 899 to 927C (1650 to 1700F). Forging of AISI 4130 steel can be performed at 954 to 1204C (1750 to 2200F).
Quenched-and-tempered properties are based on treating a .530 round for the hardening grades and a .565 round for the carburizing grades. These sizes are small enough to insure a thoroughly effective quench. Thus, the charts reflect typical values that may be expected of fully-hardened steels.

RE: heat treating 4130 steel. 23 Feb 05 14:25. Your austenitizing temperature of 1600 deg F is ok, the furnace soak at temperature should only be 30 minutes ( at 1600 deg F for 30 minutes) not 2 hours. Immediately quench in oil (this is most important to perform as rapidly as possible).
4130 and 4140 Heat Treatments - Industrial Heating
For 4130 steel, the recommended heat treatment  consists of heating to austenitizing temperature, typically 1600F (870C), followed by water quenching. Water quenching will achieve a higher as-quenched hardness than oil quenching.
4140HW Alloy Steel Technical Data
optimum heat-treat response in heavier cross-sections. You find 4140HW in a variety of bar and tubing applications in quenched and tempered conditions. Yield strengths range from 110 ksi through 140 ksi, but we can temper it to other strength levels. When compared with standard 4140 heat treated to

Alloy Steel Heat Treating Normalizing, Annealing Temperature Table Chart. Temper at 110-1225. The specific annealing cycle is dependent upon the alloy content of the steel, the type of subsequent machining operations and desired surface finish. Frequently, these steels, with the exception of 4340, 50100, 51100, and 52100, are hardened and tempered to a final machinable hardness without preliminary heat treatment.
