Product Introduction
4340 alloy steel bar is used heavily in the aerospace industry due to its ultra-high strength. When heat treated it is known for its toughness while preserving good fatigue strength. For highly stressed parts it is excellent choice. It can be machined by all customary methods. This material is available in both vacuum melt (VM) and air melt (AM)
EN24 Engineering Steel is easy to treat and temper and is supplied hardened and tempered. The alloy offers a good combination of strength, ductility and wear resistance. It is a very high strength alloy engineering steel.
