Forged Crankshaft - Materials and Process


Crankshaft Machining Process - Balu Crankshafts
_______________

_______________

Kobe Steel develops new forging method for built-up crankshafts used in ship engines - 2013
http://www.kobelco.co.jp/english/releases/2013/1188623_13522.html


A steel ingot is heated in an oven to about 2,200 degrees F amd is then placed in a forging die and squeezed into the approximate shape of the desired crank profile. This “squeezing” is performed either by a hammering or pressing process.

Machinability - AISI Rating






Machinability of a material can be defined as the ease with which it can be machined.

Machinability can be expressed as a percentage or a normalized value. The American Iron and Steel Institute (AISI) has determined for AISI No. 1112 carbon steel, a machinability rating of 100%.
