Isis Metals stands out as a reliable manufacturer and supplier of Incoloy 800H Forgings right in Manila, Philippines. They provide top-notch forged components that are built for exceptional strength and heat resistance. Incoloy 800H is a unique nickel-iron-chromium alloy, enhanced with controlled amounts of carbon and aluminum-titanium to boost its performance at high temperatures. These forgings are known for their remarkable creep and rupture strength, along with excellent resistance to oxidation, carburization, and scaling, even in extreme heat. With a commitment to precision engineering and adherence to international standards, Isis Metals’ Incoloy 800H Forgings are perfect for sectors like chemical processing, power generation, heat treatment, and furnace component manufacturing.
Incoloy 800H Forgings are made up of Nickel (30–35%), Iron (the rest), Chromium (19–23%), plus small amounts of Aluminum (0.15–0.60%), Titanium (0.15–0.60%), and Carbon (0.05–0.10%). This alloy boasts a tensile strength of about 550 MPa, a yield strength of around 275 MPa, and an elongation of 30%, ensuring it can withstand thermal stress effectively. Incoloy 800H is particularly resistant to oxidation and corrosion at temperatures reaching up to 1100°C (2010°F), maintaining its structural integrity and mechanical strength even under intense heat and pressure.
