GH3030 High Temperature Alloy Suppliers
GH3030 High Temperature Alloy Suppliers
GH3030 is a nickel-based solid solution strengthened high-temperature alloy, mainly used in components with operating temperatures below 800℃-1100℃ (such as turbine engines) because it has high plasticity, resistance to thermal fatigue and excellent weldability.
What is the equivalent grade of GH3030?
GH3030 has a similar chemical composition to Nimonic 75 and is commonly used in applications requiring nickel-chromium-iron alloy properties that meet ASTM B168 standards.
