Superalloy is widely used to produce the high temperature components for gas turbine in the field of aviation, naval vessels and industry, such as turbine blade, guide blade, turbine disc, high pressure compressor disc, combustor, and also production of energy conversion devices, such as aerospace craft, rocket motor, nuclear reactor, petrochemical equipments, coaly transforming and so on.
Heat treating fixture
Turbine engine parts - mechanical gears, gear shaft, main axis, blade
Mechanical parts - bolt and nut, fastener
Heat treatment furnace flask and components, especially in the carbonization.
These materials must stand up to high heat, extreme oxidation potential and recycling.
The alloy is usually produced by AOD / EAF followed by electroslag refining (ESR or VAR) if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different level according to the buyers' requirements.
Bars are usually supplied bright in the solution annealing condition.
Final heat treatment - heat treatment / QT / solution treatment
Black bar / Flat bar / square bar
Bright - peeled + polishing /centerless grinding /peeled + slidabrading
Forged - ring / pipe casing / discs / shaft
Round bar / Wire rod (Diameter): 5.5mm to 800mm
Square bar / Flat bar: 10mm to 800mm
Plate / Sheet steel / Steel strip: 0.5mm to 2500mm
Width: 8mm to 1200mm
Length: random length or based on the customer's special requirement.
Forged steel shape: stepped shafts with flanks / discs /tubes /slugs /donuts /cubes /other different shapes based on OEM.
