AISI 4140 Chrome-Molybdenum High Tensile Steel

AISI 4140 is a chromium-molybdenum alloy steel.The chromium content provides good hardness penetration,and the molybdenum content ensures uniform hardness and high strength.AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness.AISI 4140 Alloy Steel (UNS G41400)Sep 07,2012 4140 steel number spot#0183;AISI 4140 Alloy Steel (UNS G41400) Image Credits Phonlamai Photo/shutterstock.Alloy steels are designated by AISI four-digit numbers and comprise different kinds of steels,each with a composition which exceeds the limitations of B,C,Mn,Mo,Ni,Si,Cr,and Va set for carbon steels.AISI 4140 alloy steel is a chromium-,molybdenum-,and manganese-containing low alloy steel.AISI / SAE 4140 Alloy Steel - AISI 4140 Forgings All General characteristics of 4140 Alloy Steel.AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents.Its chemical composition is as follows.AISI/SAE 4140 grade is a versatile alloy with good atmospheric corrosion resistance and reasonable strength.It shows good overall combinations of strength,toughness,wear resistance and fatigue strength.
