Technical specifications - DIN EN -10302. 100% Ultrasonic test ASTM E2375 /SAE AMS 2154 /SEP 1923 /GB/T 4162 /EN 10228-3.
TECHNICAL SPECIFICATION - DIN X6CrNiWNb16-16
MATERIAL CATEGORY - High temperature high strength steel and superalloy
The alloy is usually produced by AOD/VIM/VOD followed by electroslag refining (ESR) 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
MATERIAL SPECIFICATIONS - DIN 17742, 17460, 17480 (2002/1992), DIN EN 103021, 10296, 10095
Round bar / flat bar / square bar / forge piece
Bright - peeled + polishing / centerless grinding / peeled + slidabrading
Forged - ring / pipe casing / discs /shaft

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.
