Fajar Metals, a reputable manufacturer and supplier based in Jakarta, Indonesia, specializes in producing durable and corrosion-resistant Incoloy 800/800H/800HT Stud Bolts. These bolts are specifically designed to withstand high temperatures and harsh industrial environments. Crafted from high-strength nickel-iron-chromium alloys, they excel in resisting oxidation, carburization, and thermal fatigue. With a range of thread sizes and finishes available, they meet industry standards like ASTM B408 and ASME B18.2.1. Perfect for critical fastening needs in sectors such as chemical processing, power generation, and oil and gas, these fasteners ensure reliable performance even in extreme heat and corrosive conditions.
Incoloy 800/800H/800HT Stud Bolts are primarily made up of Nickel (30–35%), Chromium (19–23%), and Iron (the balance), with carefully controlled amounts of Aluminum, Titanium, and Carbon. These specific grades are tailored for various temperature and stress scenarios, with 800H and 800HT providing improved creep and rupture resistance. Their mechanical properties boast a tensile strength of 500–600 MPa, yield strength exceeding 200 MPa, and elongation of up to 45%. These features guarantee that the stud bolts maintain their strength, stability, and resistance to stress corrosion cracking, even when exposed to high temperatures for extended periods.
