Product Description

DIN/EN 10297-1 42CrMo4 +QT Steel Pipe For Oxygen Bottle

Chromium-Molybdenum Steel 42CrMo4 is suitable for oxygen cylinder and bottles with excellent corrosion resistance, high wear resistance and good strength properties. Steel pipe 42CrMo4 +QT is used for oxygen gas bottle or tank, bearing retaining parts. It's also used in vehicle, vessel manufacturing, machine engineering (e.g. crankshafts, pinions, balancer shafts). The steel shows high resistivity to static and dynamic loading. Lowest working temperature -20 °C.
