17Mn4 Boiler Plate Steel
17Mn4 pressure vessel plate is an alloy structural steel. 17Mn4 pressure vessel steel plate is used in engineering structures, such as high-strength shafts, bolts and nuts, gears, pinions and main shafts, large gears for locomotive traction, supercharger drive gears, Pressure vessel, rear axle, gear loaded connecting rods and spring clamps.
In addition, 17Mn4 pressure vessel plate material can also be used for oil drill pipe joints and fishing tools in deep wells below 2000 meters, and can be used for bending machine molds, etc.
