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 GH4049 alloy rod will also increase.
GH4049 is a Ni-Co-Cr-based deposition hardening deformation superalloy, the application temperature is lower than 950℃. The alloy has good oxidation resistance below 1000°C, and high high-temperature compressive strength below 950°C, which is suitable for the production of natural gas turbocharger blades with operating temperatures ranging from 850°C to 950°C. The key equipment includes hot rolling and forging bar stock and free forging turbine blades.
Application and characteristics of GH4049 superalloy
Alloys have been used to make aircraft engine turbine blades and other high temperature load-bearing parts. After a long period of manufacture and application, it has become one of the most widely used foliar raw materials.
Compared with similar nickel-based alloys in the same way, the alloy's hot working process plasticity is weak, but after electroslag remelting or vacuum pump electric remelting, its production and processing plasticity can be improved, with fracture at 1000 ° C ~ 1170 ° C The toughness is increased by 1~3 times.
Heat treatment process rules and regulations:
1200℃±10℃ heat preservation for 2 hours air cooling+1050℃±10℃ heat preservation for 4 hours air cooling+850℃±10℃ heat preservation for 8 hours air cooling, HB363~302
GH4049 is a nickel-based aging-strengthened alloy with high high temperature strength below 950 degrees, small notch sensitivity, good oxidation resistance and fatigue strength, but poor hot working plasticity. Vacuum consumable or electroslag remelting can improve its heat processing plasticity
GH4049 alloy has been used to make aero-engine turbine blades and other high-temperature load-bearing parts. After long-term production and use test, it has become one of the most widely used blade materials.
The new process of constant temperature toughness rolling is applied to the production practice of GH4049 alloy hot-rolled bars. The production process and product quality are relatively stable, and the products can meet the needs of the market in large quantities, so they have been well evaluated by users, both economic and social benefits. relatively significant.

For Germany, the largest economy in Europe, the impact of the Russian-Ukrainian conflict on the natural gas market is the most obvious. This also exposed the serious dependence of some German industrial enterprises on Russian natural gas. Some analysts pointed out that the instability of natural gas supply has had a big impact on the German economy and threatened its market competitiveness because alternative energy supplies will not be cheap and difficult to come quickly. Increased uncertainty over natural gas supplies is putting enormous pressure on German manufacturers in sectors ranging from steelmaking to chemical GH4049 alloy rod for the time being, but the market demand for GH4049 alloy rod in the future will also change with the influence of various external factors.
