TYPICAL APPLICATIONS
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.
Mechanical parts - connecting rod, bolt and nuts.
Multi-diameter shaft, pressure vessel parts.
Power generation – turbine fasteners – boiler support rods.
Process plant – fasteners, mechanical gears, gear shaft, main axis, valve rod.
PRODUCT DESCRIPTION
12Cr1MoV is usually produced by EAF + VD + LF / BEF 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 black in the annealed condition.
Final heat treatment - normalized + tempered
