4140 is an alloy steel that is supplied in either the annealed or prehardened condition. The prehardened condition is heat treated to a medium hardness (HRC 28/32) and is designated as 4140 HT. 4140 annealed is supplied in the soft condition and can be hardened to RC 54. 4140 annealed is designated as 4140 Ann or simply 4140. 4140 HT is supplied in many forms such as hot rolled or turned , best supplier of gb t 3077 12cr1mov alloy steel plate
Annealed SAE-AISI 4140 is SAE-AISI 4140 steel in the annealed condition. It has the highest ductility compared to the other variants of SAE-AISI 4140 steel. The graph bars on the material properties cards below compare annealed SAE-AISI 4140 to: SAE-AISI wrought steels (top), all iron alloys (middle), and the entire database (bottom).
This process occurs in steel when it is worked, machined or heated. When 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.
