42CrMo4, 1.7225, 42CrMoS4, 1.7227, AISI 4140 description. Structural steel, strong and hardenable. With this steel one can achieve very good properties on the whole cross-section (while quenching in oil, the max diameter is 70mm, for quenching in water it is 50mm). In the surface hardened condition in achieves a hardness of 54-59 HRC on the 708M40 (BS ) - Worldwide equivalent gradesEuropean equivalent grade for Alloy special steel 708M40 (BS ):42CrMo4 (1.7225) Cross reference table for Steel 708M40 (BS ) and its European equivalent 50CrMo4 (1.7228) ( EN )
May 17, 2018 · 708M40, also known as EN19, is a high tensile alloy steel, often hardened or tempered to the T condition. With a combination of good ductility and shock resistance, 708M40 is suitable for applications with very high loading such as engine gear boxes. 709M40 Chemical composition, 709M40 - Steel gradesThis page cover the Mechanical Properties, Chemical Element, Cross Reference of UK B.S. 709M40 steel grade, Application Specification for wrought steels for mechanical and allied engineering purposes.
