XC18S Air 9160/C - Detail

XC18S Air 9160C wrought steels used in aeronautical constructions

XC18S is a simple structural carbon steel used in the production of low-load machine parts and structures with good weldability, not requiring high strength properties in a heat-treated state.In the annealed state, the steel is characterized by good machinability, while in the normalized state, the material shows a much better susceptibility to mechanical cutting.

XC18S steel is supplied mainly in the form of round bars, is intended for connecting rods, connectors, shafts, overhead cranes, bolts, pins, bushings, control shafts, axles, keys, rivets, wedges and hubs.
