Product Desciption
4340 40crnimo Sncm439 1.6511 En24 Special Alloy Tool Die Mould Round Steel
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 is a very high strength steel alloy which is hardened and tempered before supplying and has nickel, chromium, molybdenum making it high tensile steel strength, with good ductility and wear resistance. With relatively good impact properties at low temperatures, EN24 is also suitable for a variety of elevated temperature applications. EN24 round bars have good internal strength and high external strength, which makes it highly wear resistant. EN24 steel round bars offer good combination of ductility, strength and wear resistance. En24 is a very high strength alloy engineering steel.
Features
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.
