4140 HT Alloy TG&P
4140 HT Turned, Ground & Polished Precision Shafting material is quenched & tempered, stress relieved, machine straightened and turned ground & polished. I.T.S. stocks this grade in both metric and standard sizes. Alloy 4140 is widely used as an alternative to carbon steel where strength and fatigue are a concern. It is a general-purpose alloy used where substantial strength, toughness, and hardness are required. Through tempering, quenching, and the cold finishing process, the result is improved strength and ductility, improved toughness, better fatigue resistance, and superior surface condition.
Meets ASTM A108
