Fracturing Behavior of Metalware Made of 30KhGSA Steel

The reasons for fracture of fasteners made of 30KhGSA steel were analyzed. It was found that, in the case of fracture of bolts in the package connecting the frame elements, the damage of the bolts is the result of the fretting corrosion due to the mutual friction between bolts and elements of skin,...
