MAIN FEATURES AND MELTING PROCESS
The steels shall be manufactured by melting process EAF + LF + VD, EAF + LF + VD + ESR, IFF + ESR, VIM + VAR Melted and shall be finished by hot-rolled / hot forged / cold finished.
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.
PRODUCT PROFILE AND DIMENSIONS
Round bar & Disc (diameter): 5.5mm to 800mm
Square bar / Flat bar: 10mm to 800mm
Length: random length, fixed length or based on the customer's special requirement.
Steel strip: T0.50 ~ 3mm X W10 ~ 1000mm X Coil
Heavy/middle plate via hot rolled: T60 - 400mm X W100 - 1200mm X L1000 - 4000mm
Forging piece: stepped shafts, other different shapes based on OEM.
