With this composition grade, HASTELLOY X has excellent resistance to cracking and stress corrosion; therefore, this alloy is mostly used in petrochemical industries.
HASTELLOY X nickel-based alloy has excellent resistance to stress rapture at a high temperature of about 1200 degrees C. both the hot rolling and cold rolling processes are applied on HASTELLOY X alloy.
We can make strips and sheets of HASTELLOY X by hot working, and we can get strength and works harden shapes by cold working.
Grade HASTELLOY X Nickel Alloy Features
HASTELLOY X grade is not magnetic. It offers excellent oxidation resistance up to 1204 °C and great strength up to 816°C. It is often utilized in jet engines with high temperatures. In carburization and nitriding conditions, HASTELLOY X can resist efficiently.
HASTELLOY X alloy is used in industrial furnace applications because of its oxidation resistance and capacity to retain good ductility even after extended exposure to very high temperatures. Materials made of the HASTELLOY X alloy can be cold rolled to different tempers. It is simple to make. HASTELLOY X maintains excellent corrosion resistance.
At temperatures where metal may be cut, nickel alloys are more durable than other materials. Tooling must minimize cutting pressures while maximizing edge strength to machine nickel alloys like grade HASTELLOY X alloy.
Most importantly, HASTELLOY X alloy is known for its remarkable resistance to reducing and carburizing conditions, high heat and oxidation resistance, and excellent resistance to chloride stress corrosion cracking.
Grade HASTELLOY X Nickel Alloy Welding
Several welding techniques, including manual argon arc welding, inert metal gas-shielded welding, gas tungsten arc welding, and plasma arc welding (PAW), can join HASTELLOY X alloy. The preferred method of welding is pulse arc.
The material needs to be treated with a solid solution before welding to get rid of oxide scale, oil stains, and other defects.
To achieve a bright metal surface, areas about 25 mm wide near the weld must be polished.
Low heat input is used during welding, and the interlayer temperature is kept below 100 °C. Pre-weld and post-weld heat treating is not necessary when using HASTELLOY X alloy.
