Product Introduction

Incoloy 800HT tube is a high alloy material based on elements such as iron, nickel and chromium. One of the biggest advantages of ASTM B407 UNS N08811 pipe is its ability to resist oxidation and corrosion at high temperatures. In addition, Incoloy alloy 800ht also has excellent creep and thermal fatigue resistance. Incoloy 800ht seamless tubing is widely used in industries such as aerospace, power generation, chemical processing, and oil and gas exploration.

Incoloy 800H VS 800HT

Service Temperature: Incoloy 800H is suitable for temperatures up to 1100°C (2010°F), while Incoloy 800HT can be used at higher temperatures from 1100°C (2010°F) to 1300°C (2370°F).
Creep Resistance: 800HT has better creep resistance than 800H and can maintain the structural stability of the material under higher temperature and stress conditions.
