16CrMo44 1.7337 AISI A182 F12 Hot Forged Alloy Steel Bar

16CrMo44/1.7337  is a low-alloy steel containing chromium and molybdenum as strengthening elements.It has good mechanical property similiar like Chinese grade 15CrMo. This materail is generally used in the quenched and tempered condition.

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.

Forging of this steel should be carried out between 2200 and 1650 º F (1200 and 900 º C). The lower the finishing temperature from forging, the finer will be the grain size. This alloy should ideally not be forged below 1650 º F (900 º C) and should be slow cooled after forging.
