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, Mechanical gears, gear shaft, main axis, valve rod.
Mechanical parts - connecting rod, bolt and nut, Multidiameter shaft and pressure vessel.
DIMENSIONS AND FORMS
Round bar (Diameter): 5.5mm to 550mm
Wire rod (Diameter): 0.2mm to 16mm
Square bar / Flat bar: 3mm to 800mm
Length: Fixed length or random length or based on the customer's special requirement.
Sheet steel via cold rolled: THK 0.5 - 6mm X W10 - 1000mm X L1000 - 2000mm
Steel strip via cold rolled: THK 0.1 - 3mm X Width 5 - 200mm X L (or in coil form)
Forging piece: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM.
