Description
EN19 Hex Bar / SAE 4140 Hex Bar
EN19 Hex Bar also recognized 708M40 in BS 970 standard, is a High Quality alloy steel for general mechanical and engineering purposes. EN19 steel is characterized by its 1% chromium and molybdenum content. It is also regarded as equivalent steel grade to 42CrMo4 steel in EN standard or 4140 steel in ASTM standard. EN19 steel material is known for its excellent combination of toughness, strength, and wear resistance. It is widely used to make components for machinery, automotive parts, gears, shafts, axles, and other applications. The “EN” prefix indicates that EN19 conforms to European standards, and the number “19” specifies a particular steel grade within the EN standards.
EN19 can also be supplied in Round Bars, Flat Bars, Plates, Black Bars, Forged Bars, Bright Bars etc. for any requirement you can contact us.
EN19 also known as 708M40 / 709M40 and AISI 4140 comes treated in the annealed as rolled. We can offer EN19 ia a high quality alloy steel with good tensile strength. We can supply in diameters, squares, and flats from stock. Cut to length if required. It is renown for its wear resistance properties and where high strength properties is required.
EN19 Hex Alloy Steel Stands out for its high tensile strength, versatility, and adaptability to various heat treatment processes. Its unique combination of chromium and molybdenum makes it a preferred choice for applications requiring high strength and durability. Whether it’s automotive components, machinery parts, or in the Oil & Gas industry, EN19 material has proven its mettle time and again.
