GH 3536 - Detail

When up to 1200 ℃ with excellent oxidation resistance
Low good high temperature strength
"Very good formability and weldability
"Very good resistance to stress corrosion cracking
Due to high temperatures in all kinds of atmosphere corrosion resistance, and has excellent high temperature strength, GH536 has been widely used in various high temperature environment.
Typical applications:
Low industrial and aviation turbine (combustion chamber, the structure of the rectifier, cover)
Low industrial furnace parts, supporting roller, grating, ribbons and radiant tube
Low oil chemical spiral tube in the furnace
Low high temperature gas cooled reactor
