sae4140 steel is a low-alloy iron steel containing chromium and molybdenum as strengthening elector.
sae 4140 material we supply includes hot rolled steel bar/steel rod such as steel round bar, steel square bar, hexagonal steel bar and forged steel bar.
 
It's Chemical composition is shown as below form:
 

SAE	C	SI	MN	S	P	Cr	Mo
4140	0.48-0.53	0.15 - 0.35	0.70-1.00	0.035  (max)	0.035  (max)	0.80-1.10	0.15-0.25

 
1. Advantages:
sae 4140 steel is a versatile alloy steel with good atomspheric corrosion resistantance and reasonable strength. It shows good overal combination of strength, toughness, wear resistance and fatigue strength.   
 
2. Application: sae 4140 steel is used as forgings in the aerospace and oil and gas industries, and has myriad uses in the automotive, agricultual and defense industries. Typical usages are forged gears, shafts and spindles, fixtures, jigs, collars.
