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
Pressure vessel, seamless pipe
PRODUCT PROFILE & DIMENSIONS
Round bar / Wire rod (Diameter): 5.5mm to 450mm
Square bar / Flat bar: 3mm to 1200mm
Length: Fixed length or random length or based on the customer's special requirement.
Heavy/middle plate via hot rolled: T60 - 400mm X W60 - 1000mm X L1000 - 5000mm
Sheet steel via cold rolled: T0.5 - 6mm X W100 - 1000mm X L1000 - 2000mm
Steel strip via cold rolled: T0.1 - 3mm X W5 - 200mm X L (or in coil form)
Forging piece: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM.
