1. What is Incoloy 800HT Round Bar?

Incoloy 800HT Round Bar is manufactured from a nickel-iron-chromium alloy specifically designed for high-temperature service requiring excellent creep and rupture strength.

The UNS designation of Incoloy 800HT is N08811.

The commonly associated Werkstoff Number is 1.4959.

Incoloy 800HT is a nickel-iron-chromium alloy optimized for long-term elevated-temperature service.

A commonly applicable specification is ASTM B408 / ASME SB408, subject to the exact product requirements.

Both are designed for high-temperature service, while 800HT has more tightly controlled chemical composition and grain-size requirements intended to provide enhanced creep and rupture properties for elevated-temperature applications.
