westyorkssteel.comWhen 4130 is heated and held at 1,525 degrees, the crystalline structure of the steel begins to revert back to a malleable state. Fully annealed 4130 has a tensile strength of 81,200 pounds per square inch and a Rockwell hardness of 95.
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).
Alloy 4130 is tempered at between 750 F and 1050 F, depending upon the strength level desired. The lower the tempering temperature the greater the strength. Other Comments The 4130 alloy is a through hardening alloy and should not be case hardened.
4140 heat treated round bar up to 2.5 dia is Rc 25-34 (255-321 BHN) and the UTS is listed as 125 KSI minimum. The yield is 105 KSI minimum. I know you asked about 4130, but this is the best I could do without really digging. This info is from a LaSalle Steel handbook.
Forging. Type 4130 steel should be forged between 2250 and 1750 F (1230 and 950 C.) The lower the finishing temperature from forging, the finer will be the grain size. If the alloy is forged at too low a temperature, there is a risk of the formation of a non-uniform structure in certain areas of the forged part,how hard is 4130 steel
Steels are generally 66% heavier than aluminum but specific strength, the ratio of strength to density, is the property of interest for aircraft designers. Of the five materials, 440C stainless steel has the highest specific strength, followed by 4130 alloy steel, 7075-T6 aluminum, and 2024-T3 aluminum.
4140 is relatively easy to harden. Hardening steels involves the basic process of heating the steel to organize the crystalline structure in a uniform way and then rapidly cooling it by quenching it to lock the molecular make-up of the steel. However, different steels have different hardening steps to follow.
