Auto steel – steel bar for crankshaft

Auto steel – steel bar for crankshaft. Crankshaft is a shaft driven by a crank mechanism, consisting of a series of cranks and crankpins to which the connecting rods of an engine are attached.

Major crankshaft steel materials:

• Carbon steel bars used to produce crankshaft low and medium speed engines.

 Materials: aisi 1035, aisi 1040, aisi 1042, aisi 1045, aisi 1050, aisi 1055, aisi 1037

• Alloy steel bars used to produce crankshafts for  automobile and tractor engines

Materials:  aisi 1045, aisi 1050,  aisi 5140, aisi 1144, aisi 1345, aisi 4340 40X2H2MA

After hardening and low temperature tempering, the material will get higher strength.

• Chromium Vanadium or Chromium Molybdenum, Nickel Chromium and Nickel Chromium Molybdenum Alloy steel bars used to produce crankshafts for high speed, high power diesel engines for various applications.

Materials: ais 4130, aisi 4130h, 25CrMo4, 30XMA, aisi 4340, 817A37, 818M40, 40X2H2MA, 25H2N4WA, 25X2H4MA, 38XH3MA or SNC28.
