PRODUCT DESCRIPTION
Alloy structural steel is provided with higher yield strength, tensile strength, endurance strength, yield ratio (about 0.85 generally ) enough plasticity and toughness.
The alloy is usually produced by 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 bright in the annealed condition.
Final heat treatment - quenched and tempered.
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.
Power generation – turbine fasteners – boiler support rods.
Process plant – fasteners.
Process plant – fasteners.
Mechanical gears, gear shaft, main axis, valve rod.
Mechanical parts - connecting rod, bolt and nut.
Multidiameter shaft, pressure vessel.
