AISI or SAE 4150 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. Its chemical composition is shown to the right:
AISI/SAE 4150 grade is a versatile alloy with good atmospheric corrosion resistance and reasonable strength up to around 600 º F (315 º C). It shows good overall combinations of strength, toughness, wear resistance and fatigue strength.
FORGING 4150 ALLOY STEEL
This steel should be forged between 2200 and 1600 º F (1200 and 870 º C.) The lower the finishing temperature from forging, the finer will be the grain size. This alloy should ideally not be forged below 1600 º F (870 º C) and should be slow cooled after forging.
APPLICATIONS OF AISI / SAE 4150
This alloy is used as forgings in the aerospace and oil and gas industries, and has myriad uses in the automotive, agricultural and defense industries, Typical uses are forged gears, shafts, and spindles.
The alloy is heat treated to render it suitable for machining, and to meet the mechanical property ranges specified for its particular applications.
ANNEALING
Annealing of 4150 forgings may be carried out by transferring the part straight from the forging operation to a furnace held at a suitable temperature, around 1500 º F (815 º C), for annealing, holding for a suitable time then furnace cooling, forming a structure suitable for machining. This kind of treatment is best used for parts with simple shapes. If some areas of a forging will finish much colder than others then a uniform structure will not be obtained, in which case a spheroidizing anneal at around 1380 º F (750 º C) might be used. It is safe to say that experience alone will decide the best type of annealing treatment to be used prior to machining.
