pneumatic valve, high temperature alloy spring GH has the following features:
. Easy workability
. When ℃ has high tensile strength, fatigue strength, creep strength and rupture strength
. When ℃ with high oxidizing
. Has the stable chemical properties in low temperature
. Good welding performance

pneumatic valve metallographic structure of the hot spring GH:
alloy austenitic structure, precipitation hardening generated after gamma 'phase with the excellent mechanical properties. In the process of heat treatment on grain boundary generated at the delta facies is the best plastic.

pneumatic valve corrosion resistance of hot spring GH:
no matter in the high temperature or low temperature environment, alloy has excellent resistance to stress corrosion cracking and pitting. Alloy under the high temperature oxidation resistance is particularly outstanding.

pneumatic valve hot spring GH application range of application areas are:
because when ℃ high temperature strength and excellent corrosion resistance, easy workability, can be widely used in all kinds of high demand.
