The authors studied the effects of Cb on the phisical mechanical, chemical and welding properties of low carbon Cr-Mo steels and medium carbon Ni·Cr steels.
The compositions of the samples are as follow:-
From the experiments, it was concluded that Cb is a valuable alloying element for low alloy steels and it has several advantages such as inhibition of air hardening characteristics, increase in strength at high temperature, increase in corrosion and oxidation resistances and improvement of weldability, although it lowers the impact value more or less. But it is questionable how much it may be used in the industrial scale because of its high cost.
