Product Details
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.
