Conclusions
-
1.
Isothermal quenching of cutter bar parts for the KKKh-3 corn harvester made of SCh 18-36 cast iron doubles the wear resistance by comparison with bulk quenching and tempering.
-
2.
The increased working life of these parts produces substantial savings, since it reduces the number of spare parts required.
-
3.
Isothermal quenching also results in lower labor costs, since the tempering operation is eliminated, thus saving 0.20 min per piece.
