What is the Difference Between Nickel-based Alloys and Ordinary Stainless Steel

Australian alumina ban disrupts Rusal Inconel625 powder prices for chemicals. Patel said. "One possible outcome could be Chinese buyers buying alumina and reselling it through eastern Russian ports." Rusal has a 20% stake in the Queensland Alumina Refinery, which has a capacity of 3.95 million tonnes a year, thus providing Rusal with 790,000 tonnes a year, Patel said. In addition, Rusal's Nikolaev refinery in Ukraine, which has an annual capacity of 1.75 million tonnes, has been suspended due to the conflict, he added. WoodMac said Rusal was also experiencing supply chain problems at its 2 million tonne a year Aughinish refinery in Ireland.

In fact, in essence, nickel-based alloys are also a kind of stainless steel. They are just special stainless steels. The chemical composition is also different from ordinary stainless steel. Nickel-based alloys are high in nickel, high chromium, and high molybdenum. A high-alloy stainless steel of high-alloy stainless steel.

Among them, the famous steel is 6% Mo (254SMo). This steel has good local corrosion resistance. It has good pitting corrosion resistance and better stress corrosion resistance under the conditions of seawater, aeration, clearance and low-speed scouring (PI≥40). It is an alternative material for nickel-based alloys and titanium alloys. Secondly, it has excellent high temperature or high temperature corrosion resistance or corrosion resistance. It is irreplaceable for 304 stainless steel. In addition, from the perspective of the classification of stainless steel, the metallographic structure of special stainless steel is a stable austenitic metallurgical structure.

Because nickel-based alloy is a high-alloy high-performance special material, its manufacturing process will be more complicated than ordinary stainless steel products. At present, most of them still rely on traditional processes for manufacturing, such as: infusion, forging, rolling and other processes.
