Description

Billets with the diameter from 5.12 up to 13.78 inch are produced as saleable products. There are also billets for production of forgings, tubes (tubular billets), bars and shapes. Billets over 13.78 inches in diameter are supplied based on customer requirements. Billets can be made both from Russian and foreign titanium and heat resistant alloys.
