The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring: Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the Nickel-based Alloy?
What is GH4049 (GH49) nickel base alloy?
GH4049 is a nickel-based superalloy, which is an age-hardening alloy. The corresponding grade is GH49. Its nickel content is about 70%. After the alloy is remelted by electroslag or vacuum arc, its processing plasticity can be improved. GH4049 superalloy has good hot and cold working properties. The alloy has good oxidation resistance below 1000 °C high temperature environment, high high temperature strength below 950 °C, small notch sensitivity, good oxidation resistance and fatigue strength. , poor single hot working plasticity
Main processing properties of GH4049 (GH49) nickel-based alloy
Compared with nickel-based alloys of the same kind, GH4049 superalloy has poor hot working plasticity. It is suitable for making gas turbine working blades with a working temperature of 850-950 °C. It is mainly used to make turbine blades for aviation, naval and industrial gas turbines. , high-temperature components such as guide vanes, turbine disks, high-pressure compressor disks and combustion chambers; also used in the manufacture of space vehicles, rocket engines, nuclear reactors, petrochemical equipment, and coal conversion and other energy conversion devices.
The nano-surface crystal layer was prepared on the surface of GH4049 nickel-based superalloy by the treatment process. The effects of different ultrasonic shot peening intensity and shot peening time on its yield strength, tensile strength and microhardness were analyzed. Residual stress distribution of the specimen after nanoization. The research results show that the increase of shot peening time has no direct relationship with the improvement of material strength, and with the increase of shot peening time, the strength of the material will decrease due to the damage of the material surface. After ultrasonic shot peening, the microhardness was significantly improved compared with that of the untreated specimen, and a compressive stress layer of about thickness was formed on the surface of the specimen, and the large compressive stress far exceeded the yield limit of the material.

Since the beginning of this year, China's macro policies have made continuous efforts to stabilize economic growth. America and Europe are raising interest rates to control inflation. On March the European Central Bank left its three key interest rates unchanged and began to scale back its asset-purchase programme. Then the Federal Reserve raised the target range of the federal funds rate by 25 basis points to 0.25%-0.5%. The accelerated tightening of monetary policies in the US and Europe pushed capital back to the US and increased interest rates, which will definitely increase the risk of RMB depreciation and capital outflow. The price and market of the Nickel-based Alloy will also be affected, resulting in a range of fluctuations. You are welcome to contact us for the latest quotation of Nickel-based Alloy.
