MAIN FEATURES AND MELTING PROCESS
The steels shall be manufactured by melting process EAF+ VD, EF + ESR remelted. VIM + ESR can be handled by agreement.
Forgings may be furnished in one of the following conditions: stress relieving; annealing; solution treatment; solution treatment and ageing; normalizing; normalizing and tempering; or quenching and tempering.
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 rods.
Mechanical parts - connecting rods, bolts and nuts.
Multidiameter shafts.
PRODUCT PROFILE AND SIZE
Rod / round bar / disc (diameter): 6.0 to 850 mm
Square bar / flat bar: 10 to 600 mm
Length: random length, or based on the customer's special requirement.
Steel strip: T0.30 ~ 3 X W10 ~ 200 mm X Coil
Heavy/middle plate via hot rolled: T6 ~ 200 X W10 ~ 1500mm X L1000 ~ 12000 mm
Forging piece: stepped shafts, and other different shapes based on OEM.
