ASTM B168 N08800 - Characteristics and applications of nickel-iron-chromium alloys

ASTM B168 N08800 is manufactured according to ASTM B168 standard and is a high-performance nickel-iron-chromium alloy. Its composition mainly includes nickel, iron and chromium, of which the content of nickel is about 30~35%, the content of chromium is about 19~23%, and iron is the basic component of the alloy. This special chemical composition gives N08800 alloy excellent heat and corrosion resistance.

ASTM B168 N08800 alloy Features:

Excellent strength: N08800 alloy maintains excellent strength at high temperatures and pressures, thanks to its high content of nickel and chromium elements.

Corrosion resistance: The alloy has very high corrosion resistance, can be used in a variety of strong acids, bases and salts and other corrosive media for a long time, and also has excellent resistance to oxidizing environments.

High temperature stability: A major feature of N08800 alloy is its stability at high temperatures. It is able to operate for long periods at temperatures up to 982°C (1800°F) without losing mechanical strength, mainly thanks to the stable oxide layer formed in the alloy.

Good workability: N08800 alloy can be processed and formed by forging, rolling and drawing, and can be deformed at high temperatures.
