Abstract
A dual purpose steel having high strength, high hardness, high wear resistance, high hardenability and easy machining and therefore being equally well suited for (a) elevated temperature closed die forging (b) room temperature machine part applications, such as gears, pinions, etc.
Claims3
A dual purpose steel having both high ductility at room temperature and high strength, high hardness, high wear resistance and high hardenability at elevated temperatures above 300.degree. F. together with easy machinability, said steel having the following composition:
- ______________________________________ C .48-.53 Mn .75-.95 P .025x S .025x Si .15-.35 Ni .80-1.40 Cr 1.00-1.30 Mo .65-.85 V .04-.10 Al .015-.025 Ti .005-.015 ______________________________________
- balance Fe and usual impurities, said steel being in a non-drastic quenched condition.
A closed die forging die having both high ductility at room temperature and high strength, high hardness, high wear resistance and high hardenability at elevated temperatures above 300.degree. F. together with easy machinability, said steel having the following composition:
- ______________________________________ C .48-.53 Mn .75-.95 P .025X-.025X S .025X Si .15-.35 Ni .80-1.40 Cr 1.00-1.30 Mo .65-.85 V .04-.10 Al .015-.025 Ti .005-.015 ______________________________________
- balance Fe and usual impurities, said steel being in a non-drastic quenched condition.
A gear, pinion, piston, crankshaft or other machine part having high ductility at room temperature together with high strength, high hardness, high wear resistance and easy machinability at elevated temperatures above 300.degree. F., said steel having the following composition:
- ______________________________________ C .48-.53 Mn .75-.95 P .025x S .025x Si .15-.35 Ni .80-1.40 Cr 1.00-1.30 Mo .65-.85 V .04-.10 Al .015-.025 Ti .005-.015 ______________________________________
- balance Fe and usual impurities, said steel being in a non-drastic quenched condition.
