MAIN FEATURES AND MELTING PROCESS
The steels shall be manufactured by melting process EF, LF + EAF+ VD, IFF + ESR Melted. 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 SUPPLYING FORMS
Round bar (Diameter): 5.5mm to 600mm
Square bar / Flat bar: 3mm to 650mm
Length: random length, fixed length or based on the customer's special requirement.
Steel strip: T0.20 ~ 3mm X W10 ~ 1000mm X Coil
Heavy/middle plate via hot rolled: T40 - 400mm X W80 - 1000mm X L1000-12000mm
Forging piece: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM requirement.
