Fajar Metals, a well-respected manufacturer and supplier located in Jakarta, Indonesia, specializes in high-performance Incoloy 800/800H/800HT Valves. These valves are crafted for exceptional durability and resistance, particularly in high-temperature and corrosive environments. Constructed from nickel-iron-chromium alloys enriched with carbon, aluminum, and titanium, they are designed to uphold mechanical strength while resisting oxidation, carburization, and thermal fatigue. With a range of designs including gate, globe, ball, and check valves, they meet industry standards like ASTM B564 and ASME B16.34, making them ideal for critical operations in refineries, power plants, and chemical processing systems.
Incoloy 800/800H/800HT Valves boast a chemical makeup of Nickel (30–35%), Chromium (19–23%), and Iron (the balance), with specific amounts of Aluminum, Titanium, and Carbon varying by variant. These alloys are known for their high-temperature strength and remarkable resistance to oxidation and stress corrosion cracking. Their mechanical properties include a tensile strength of about 500–600 MPa, yield strength exceeding 200 MPa, and elongation up to 45%. The 800H and 800HT versions offer improved creep and rupture resistance, ensuring reliable performance in extended high-temperature applications.
