A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including GH4049 alloy rod.
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.

Since February, gold has enjoyed a smooth upward run on the back of surging US inflation and the brewing of war. While expectations of rate rises have also risen in tandem over this period, gold had been largely pre-priced and the underlying driver of tightening expectations had come from inflation continuing to rise to record highs. The risk aversion caused by the continued tension in the war also provided an important short-term support for gold. This will have a certain impact on the price of the GH4049 alloy rod and the market of the GH4049 alloy rod.
