AISI 4140/4142 CF Q&T<br />
ROUNDS<br />
COLD FINISH/T&P<br />
4140/4142 CF Q&T SR is a general purpose alloy used where substantial strength,<br />
toughness and hardness are required. Through tempering, quenching and the coldfinishing<br />
process, the end result is improved strength and ductility, improved toughness,<br />
better fatigue resistance and superior surface condition.<br />
4140 CF Q&T SR Rounds are also calcium-treated for improved machinability and fully<br />
stress relieved after drawing so that distortion during machining is held to a minimum.<br />
