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.
TECHNICAL SALES ASSISTANCE & SERVICE
