Sometimes, we find that custom stocking programs help our customers react faster to changes.
Alloy 4140 is a direct hardening alloy that can be quenched and tempered to obtain a wide range of hardness, ductility and strength levels. These results are influenced by both the thermal treatment applied and the alloying elements present.
The Purecut® series offers our customers the opportunity to improve machinability with the addition of Bismuth. Bismuth steels will machine equal to leaded steels without any of the environmental problems.
E4140 Aircraft Quality is a chrome-moly alloy produced in Electric Furnaces and Vacuum Degassed. When quenched and tempered, it is a relatively deep hardening steel.
This strong alloy is used for its good hardness penetration and hardness uniformity. Its high machinability and ability to maintain its properties at high temperatures make this alloy useful in many industries.
