MATERIAL INSPECTION

MATERIAL INSPECTION : Carbon          {c}                                 :                  Strength / hardness. Manganese {Mn}                         :                  Toughness. Silicon {Si}                                 :                  <0.3% deoxidizer [avoid porosity]. Chromium {cr}                            :                  corrosion resistance. Molybdenum {Mo}                       :                  1% is for creep resistance. Nickel {Ni}                                 :                  low temp application. Titanium {Ti}                               :                  used to avoid weld decay. Niobium {Nb}                              :                  used to avoid weld […]

Differential Wheel and Axle :

Differential Wheel and Axle : In this case, the load axle BC is made up of two parts of different diameters. Like simple wheel and axle, the wheel A, and the axle B and C are keyed to the same shaft, which is mounted on ball bearing in order to reduce the frictional resistance to […]
