Incoloy 800H / 800HT Plate Description
Incoloy 800H is a nickel-based alloy containing approximately 22% chromium, 39% iron, and 33% nickel, with the balance being carbon, silicon, manganese and other elements. This alloy has excellent high temperature resistance, its maximum operating temperature can reach 1100°C, and it also has good toughness and ductility at room temperature. In addition, Incoloy 800H also has excellent oxidation resistance and corrosion resistance, and can maintain a long service life in high temperature environments. Incoloy 800H plate has good processing properties and can be used for hot and cold processing. During thermal processing, the heating temperature and cooling rate should be controlled to avoid cracks and deformation. During cold working, cutting, drilling, turning, etc. can be used.
