42CrMoS4 peeled or turned steel round bar 42CrMoS4 is a one kind of Chromium-molybdenum steel similar to 42CrMo4, 4140, scm440, 42CrMo, 42CrMoA. The only difference is that 42CrMoS4 steel has limited sulphur content as 0.020%-0.035% which improve the hardenabilities and machinabilities. It's also in standard DIN 1.7227. According to different applications and processing, we can supply various delivery condistions such as 42CrMoS4 hot rolled steel bar, 42CrMoS4 cold drawn steel bar, 42CrMoS4 peeled steel bar, 42CrMoS4 turned steel bar, 42CrMoS4 ground and polished steel bar, 42CrMoS4 annealed steel bar, 42CrMoS4 normalized steel bar and 42CrMoS4 quenched and tempered steel bar which is also called 42CrMoS4 + QT steel bar, 42CrMoS4 QT steel bar or 42CrMoS4 Q&T steel bar. 42CrMoS4 peeled and turned steel bar is a kind of machining used to remove the imperfections on the hot rolled bars surface such as the scales and the d…
