4340 High Tensile Steel Interlloy Engineering Steels

Pre hardened and tempered 4340 can be further surface hardened by flame or induction hardening and by nitriding. 4340 is used in most industry sectors for applications requiring higher tensile/yield strength than 4140 can provide. Typical applications are:Heavy 4340 Steel - 4340 Steel Plate Pennsylvania Steel CorporationFLEXOR®'s dependable quality and adaptability in heat treatment allows for a wide range of physical properties that are more appealing than those of typical ASTM, AISI or SAE 4340 alloy steel. Flexor® has a comparable core hardness which typically means a more uniform hardness through any cross section.
