Stainless steels may contain nickel as another major alloying element, with a content of up to 38%, plus other alloying elements and stabilisers. The chromium content renders stainless steels corrosion resistant. Metallic stainless steel is produced mainly in the massive form (>99%); the remainder is produced in powdered form. In spite of the absence of data from animal experiments and of ...

Rotary kilnelectric furnace (RKEF) process is the main technology to deal with nickel laterite for the ferronickel alloy production in the world. However, this process needs huge amount of electric power due to the large ratio of slag to metal. Therefore, a novel process was proposed to directly produce ferronickel alloy nugget at a related low temperature from nickel laterite by the semi ...

nickel improves film resistance in some acid environments. Material Selection Many variables characterize a corrosive environment –, chemicals and their concentration, atmospheric conditions, temperature, time – so it is difficult to select which alloy to use without knowing the exact nature of the environment. However, there are guidelines: Type 304 serves a wide range of ...

conductive, aqueous solution of nickel salts. The flow of direct current causes one of the electrodes (the anode) to dissolve and the other electrode (the hode) to become covered with nickel. The nickel in solution is present in the form of divalent positively charged ions (Ni +). When current flows, the positive ions react with two electrons (2e) and are converted to metallic nickel (Ni0 ...
