4.Heat treatment of aisi 4130 alloy steel

1. Forging:Heat slowly and uniformly to 1000°C. After forging cool slowly.

2. Annealing: 780-800`C slow cooling

5.Characteristic of aisi 4130 alloy steel

(1)Good purity and homogeneity.

(2) Good machinability (Roughing, grinding and drilling).

(3) Good dimensional stability during heat treatment.

(4) Excellent preparation for nitriding, both ionic and gaseous, induction hardening to increase the mechanical properties.

6.Application of aisi 4130 alloy steel

(1)It is widely used in high-strength forgings, such as traction gear, supercharger drive gear,  rear axle, the load of connecting rod, spring clip; 

(2)It also manufactured tool joints and finish tools which used for oil wells below 2000m deep.

(3)For making welding parts; board;welding structure;high pressure pipe in the chemical industry. 

(4)For making temperature under 450°C‘s fastener in the steam turbine, boiler manufacturing.

(5)For making under the 500°C and the high pressure's flange and nut.

(6)especially used to produce the conduit pipe which is under 400°C and the barometric pressure is 300.
