MAIN FEATURES AND MELTING PROCESS
The steels shall be manufactured by melting process EAF + LF + VD, IFF + ESR 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.
Heat and product analyses shall be employed to assess the conformance of steels with required chemical compositions.
Forgings shall examined by tension and Charpy impact tests and conform to required mechanical properties such as yield strength, tensile strength, elongation, reduction of area, minimum room-temperature Charpy V-notch energy absorption, maximum annealed hardness, and section size capability. Nondestructive tests, such as magnetic particle, liquid penetrant, and ultrasonic inspection procedures, shall also be performed.
TYPICAL APPLICATIONS
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 AVAILABLE FORMS
Round bar (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
