The alloy is usually produced by IFF, LF, EAF + VD + LF followed by electroslag refining (ESR) if necessary for special purpose.
MANUFACTURING TECHNIQUE
The alloy is usually produced by IFF, LF, EAF + VD + LF followed by electroslag refining (ESR) if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied brightly in the annealed condition.
Alloy structural steels are widely used in the filed of ship, vehicle, airplane, guided missile, weapons, railway, bridges, pressure vessel, machine tools, mechanical components with a bigger sectional size and so on.
