Sahil Metals, located in Riyadh, Saudi Arabia, stands out as a trusted manufacturer and supplier of high-performance alloy products designed for tough high-temperature applications. Among their top-tier offerings are **Incoloy 800H Forgings**, celebrated for their remarkable strength, resistance to creep, and ability to withstand oxidation at elevated temperatures. This alloy is specifically crafted for high-heat environments where long-lasting structural stability and corrosion resistance are essential. Sahil Metals provides 800H forgings that meet international standards, catering to industries throughout Saudi Arabia and the GCC.
**Incoloy 800H Forgings** primarily consist of nickel (30–35%), chromium (19–23%), and iron (the balance), with carefully controlled amounts of carbon, aluminum, and titanium. In comparison to standard Incoloy 800, the 800H grade boasts a higher carbon content and a controlled grain size, which significantly boosts its creep and rupture strength at high temperatures. These forgings are reliable at temperatures reaching up to 1100°C (2010°F), offering excellent resistance to oxidation, carburization, and sulfidation. They also maintain strong structural integrity and metallurgical stability over extended service periods.
