U.S. natural gas futures rose about 5 percent to a near nine-week high as global energy prices surged on concerns over a pricing plan for energy exports, keeping U.S. LNG export demand near record highs. U.S. natural gas prices have risen despite forecasts of mild weather and lower-than-expected demand, which will allow utilities to fill up storage facilities next week. On Wednesday, Germany launched an emergency plan to manage gas supplies in Europe's largest economy. If natural gas supplies are interrupted or stopped, the German government could take unprecedented steps to limit electricity supply.
Affected by the increase in the price of natural gas, the price of the Hastelloy X alloy will also increase.
What is GH3536 superalloy (Hastelloy X alloy)
GH3536 (Hastelloy X alloy) is a nickel-based superalloy with high iron content mainly solid solution strengthened by chromium and molybdenum. It has good oxidation resistance and corrosion resistance, and has moderate durability and creep below 900 ℃. Strength, cold and hot workability and good weldability. Used in the manufacture of combustion chamber parts and other high-temperature parts of aero-engines, long-term use below 900 °C, and short-term operating temperature can reach 1080 °C. The main varieties supplied are plates, strips, pipes, bars, forgings, rings and precision castings.
GH3536 (Hastelloy X alloy) process performance and requirements
GH3536 (Hastelloy X alloy) formability alloy has good cold and hot forming
properties. Forging heating temperature 1170℃±10℃, final forging temperature not
lower than 950℃; slab hot rolling heating temperature 1150℃±10℃, final rolling
temperature not lower than 850℃; ring hot rolling heating temperature 1170℃±10℃
GH3536 (Hastelloy X alloy) welding performance This alloy has good welding process performance, and can be welded by argon arc welding, seam welding and spot welding. HGH3536 or HGH3113 wire is recommended for argon arc welding.
The microstructure of the alloy in the solid solution state is an austenite matrix with a small amount of TiN and M6C carbides. After long-term aging at 700～900℃, the main precipitation phases are M12C and M3B2, accompanied by trace μ phase and L phase. After aging at 700℃ for 200h, a small amount of σ phase appeared, but after aging at 800℃, the σ phase did not exist, and a small amount of M23C6 was precipitated, and sometimes a small amount of L phase appeared. Therefore, the alloy exhibits a certain degree of age hardening after long-term aging, which reduces the plasticity and the high temperature strength.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.
The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.
Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.
U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.
The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."
The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled Hastelloy X alloy are estimated to be influenced by international political situation changes.
