It is not done anymore because there are other finishes that are more effective than flash chroming such as REM, Micronite and others. The final surface finish is more important and should have a 10 Micro-Inch Ra finish or better. Many racing crankshafts are Ion Plasma Nitrided also. The crankshaft journals run on a hydrodynamic oil film at all times.
