800H / 800HT NICKEL BAR, ROD

Nickel Alloy 800H/800HT bar, rod, and wire are nickel-iron-chromium alloys that provide high strength an excellent resistance to oxidation and carburization at high temperatures. They also offer excellent resistance in many aqueous environments. Their nickel content makes the alloys highly resistant to both chloride and stress-corrosion cracking. Alloy 800H and Alloy 800HT are identical except for the higher level of carbon in Alloy 800H, and the addition of up to 1.00 percent aluminum and titanium in Alloy 800HT.
