  42CrMo4 steel   grade is an alloy steel for quenching and tempering. Grade 42CrMo4 products are mainly used for the manufacture of machine parts like   cylinder piston rod   and roller shafts. Steel is made in accordance with the requirements of the DIN EN ISO 683-2 standard (formerly EN 10083-3). AISI 4140/ 42Crmo4 is the most used  quenched and tempered  steel, It has an elevated harden ability, good heat resistance, excellent forging and good machinability with machine tools. It can be hardened on the surface or nitried in order to elevate the wear resistance and the fatigue strength. Quenched and tempered and  nitrited cylinder rods  can substitute the case-hardened and hardened ones, if they are not submitted to too elevated pressure. Steel grade 42CrMo4 is popular in the machine building industry and is used to make high-strength parts of compressors, turbines, working elements of heavy ground and underground equipment, and parts of agricu...

  42CrMo4+QT  means this material is in the quenched and tempered condition (+QT).  42CRMO4 (+QT) medium carbon bearing steel in the form of hot rolled/hot forged quenched and tempered seamless forged parts. This specification covers Material Grade, Homogeneity, Microstructure and Mechanical properties. Forged parts produced with this steel are used for manufacturing bearing retaining parts. All other requirements, common to medium carbon bearing steel grades in the form of rolled/hot forged,quenched and tempered ring are specified in EN 10083-3 and ISO 683-17. 42CrMo4 Equivalent Material 42CrMo4 material (1.7225 steel) equivalent to US ASTM AISI SAE, Germany DIN, British BSI, France NF, ISO, Japanese JIS and Chinese GB standard.
