1. What is SA240 Gr 800H (N08810)?

SA240 Gr 800H, also known as UNS N08810 or Incoloy 800H, is a nickel-iron-chromium alloy with a controlled carbon content (0.05-0.10%) and additions of aluminum and titanium, designed for enhanced creep and rupture strength at high temperatures. It offers excellent resistance to oxidation, carburization, and nitriding, making SA240 Gr 800H material ideal for furnace components, petrochemical reformers, and power generation equipment.

Compared to SA240 Gr 800, SA240 Gr 800H provides superior creep resistance for prolonged high-temperature exposure, while maintaining good corrosion resistance in oxidative environments.

Gangsteel’s SA240 Gr 800H stainless steel plate is engineered for industries requiring reliable performance in extreme heat, offering a robust alternative to grades like SA240 Gr 904L or SA240 Type 2507.
