Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. This nickel steel alloy’s chemical composition is designed to provide exceptional resistance to many corrosive environments. It is similar to alloy 800 but has improved resistance to aqueous corrosion. It has excellent resistance to both reducing and oxidizing acids, to stress-corrosion cracking, and to localized attack such as pitting and crevice corrosion. Alloy 825 is especially resistant to sulfuric and phosphoric acids. This nickel steel alloy is used for chemical processing, pollution-control equipment, oil and gas well piping, nuclear fuel reprocessing, acid production, and pickling equipment.

Difference between black steel bars and bright steel bars
BLACK STEEL BARS
Black Steel Bars are produced in a rolling mill by heating raw material such as billet, blooms, etc at a temperature around 1200 C through a number of rolls to achieve the desired shape and size. Some of the shapes are rounds, hexagons, flats, bars, etc. Due to the nature of the process and temperatures involved, precise control of tolerances that can be achieved in bright bars cannot be achieved in black steel bars. Therefore they are further processed to make steel bright bars for processes that require more precise accuracies. Therefore black steel bars are less expensive than bright bars.
BRIGHT STEEL BARS
Bright Steel Bars are produced from black bars by passing through dies in a cold condition or by turning the bars in a peeling machine and some other processes. They are used where specific tolerance are required such as for use in CNC machines, etc. Some times heat treatment such as annealing is done before cold finishing.
