  • Product Description

The data in your efunda link is for annealed 4140 and 4340.In an actual application,you would be using quenched and tempered material.Consequent'Toughness' is used in a couple of contexts in metallurgy and materials science.One context is 'fracture toughness' which is defined as the abilitYou are not making a fair comparison. The properties for the 4140 are listed for material annealed at 815C (1500F) Tensile 655.0 MPa (95,000 PSThe 4340 alloy steel by virtue of having nickel as an alloying element increases hardenability and increases toughness over 4140.Impact energy rel1rp metengr,It sounds like quenching and tempering both 4140 and 4340 will increase toughness (as well as hardness) compared to the annealed ..By using QT you are forming a tempered martensite structure.The quench and temper are both critical.If the heat treat is done correctly forNo,it is not due to retained austenite. There is negligible retained austenite in either 4140 or 4340 in the quenched and tempered condition.TThanks everyone for the responses.Much appreciated.
