In the petrochemical, power generation, and heat-treatment industries, pressure vessels must endure prolonged exposure to extreme temperatures and pressures. While standard austenitic stainless steels may suffer from creep and oxidation above 600°C, Incoloy 800 (UNS N08800) / 800H (UNS N08810) stands as the ideal solution due to its unique Nickel-Iron-Chromium alloy system.
Wuxi Xinshanhu Steel Co., Ltd. is a premier supplier of specialty alloys, dedicated to providing pressure vessel manufacturers worldwide with high-performance Incoloy solutions that strictly adhere to ASME and international standards.

Core Strengths of Incoloy 800 & 800H

These alloys are engineered for exceptional resistance to carburization, oxidation, and sulfidation. Incoloy 800H, the enhanced version of Grade 800, features controlled levels of carbon, aluminum, and titanium combined with high-temperature solution annealing to significantly boost creep-rupture strength.
