INCOLOY 800-SHANGHAI KANGSHENG AVIATION MATERIALS TECHNOLOGY CO., LTD.

INCOLOY 800

category：

Product Description

A nickel-chromium alloy with good strength and excellent resistance to oxidation and carburization in high-temperature atmospheres. It also resists corrosion by many aqueous environments. The alloy maintains a stable, austenitic structure during prolonged exposure to high temperatures. Used for process piping, heat exchangers, carburizing equipment, heating-element sheathing and nuclear steam-generator tubing.

STANDARD PRODUCT FORMS

Pipe, tube, sheet, strip, plate, round bar, flat bar, forging
stock, hexagon and wire.
