Aisi 4140 Alloy Steel Pipe High Pressure Steel Pipe For Producing
AISI 4140 alloy steel has high ductility. It can be formed using conventional techniques in the annealed condition. It requires more pressure or force for forming because it is tougher than plain carbon steel.
The table below highlights the chemical composition of AISI 4140:
| C(％) | 0.38～0.25 | Si(％) | ≤0.40 | Mn(％) | 0.60～0.90 | P(％) | ≤0.035 |
| S(％) | ≤0.035 | Cr(％) | 0.90～1.20 | Mo(%) | 0.15～0.30 | - |
The addition of chromium and molybdenum promotes corrosion resistance. The molybdenum can be particularly useful when trying to resist corrosion due to chlorides. The manganese in AISI 4140 is used to increase hardenability and as a deoxidizer. In alloy steels, manganese can also combine with sulfur to improve machinability and make the carburizing process more effective.
Heat Treatment
AISI 4140 alloy steel is heated at 845°C (1550°F) followed by quenching in oil. Before hardening, it can be normalized by heating at 913°C (1675°F) for a long period of time followed by air cooling.
Application
This alloy finds many applications as forgings for the aerospace and oil and gas industries, along with myriad uses in the automotive, agricultural and defense industries, Typical uses are forged gears and shafts, spindles, fixtures, jigs, and collars.
