1. What is SA240 Gr 800 (N08800) stainless steel sheet?

SA240 Gr 800, also known as UNS N08800 or Incoloy 800, is a nickel-iron-chromium alloy with approximately 30-35% nickel, 19-23% chromium, and balanced iron. It is designed for excellent high-temperature strength, oxidation resistance, and carburization resistance, making it ideal for applications in furnace components, heat exchangers, and petrochemical processing.

SA240 Gr 800 materialis particularly suited for environments requiring resistance to oxidation, nitriding, and thermal fatigue. Compared to SA240 Gr 800H, SA240 Gr 800 has a lower carbon content, offering better weldability but slightly less creep resistance at elevated temperatures.

Gangsteel’s SA240 Gr 800 stainless steel plate is engineered for industries needing reliable high-temperature performance, providing a versatile alternative to grades like SA240 Gr 904L or SA240 Type 2507.
