We supply these Incoloy 800/800H/800HT Stud Bolts in accordance with DIN, ISO, JIS or ANSI Standard.
High-temperature resistance: Incoloy 800 series stud bolts can endure temperatures reaching 1100°C (2000°F) with only minimal reduction in mechanical strength. This makes them well-suited for heat exchangers, petrochemical processing, and other high-temperature environments.
Corrosion Resistance: These alloys demonstrate outstanding corrosion resistance in both oxidizing and reducing environments. They are especially resistant to sulfuric conditions, which makes them ideal for use in settings such as pharmaceutical plants.
Creep and Rupture Strength: The blend of nickel, chromium and iron in Incoloy 800 series alloys delivers excellent creep and rupture strength at elevated temperatures. This preserves the stud bolts’ system integrity even when subjected to heat from rising mechanical stresses over time.
Excellent mechanical strength: The stud bolts in the Incoloy 800 series retain excellent mechanical properties, such as tensile strength, yield strength, and stiffness, across a broad temperature range. This ensures dependable performance and lasting durability in demanding applications.
Easy to manufacture: These alloys can be fabricated in numerous forms, including stud bolts, through conventional manufacturing methods such as hot forging and machining. This makes it possible to produce custom-sized stud bolts tailored to the requirements of specific applications.
Incoloy 800/800H/800HT Stud Bolts serve applications as varied as the industries they cater to, led mainly by the aerospace, railway, construction and automotive industries along with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Petrochemical Industry: Stud bolts manufactured from Incoloy 800 series alloys have widespread use across the petrochemical sector, particularly within refineries and chemical processing facilities. They serve in reactors, heat exchangers, piping systems and more, where contact with corrosive chemicals and elevated heat is routine
Power applications: Incoloy 800 series stud bolts serve in electrical equipment, both conventional and nuclear, for uses such as boiler components, steam turbines, exhaust systems and similar. These alloys are able to endure the high temperatures and pressures met in power generation.
Aerospace: For aerospace uses that call for lightweight, high-strength materials capable of enduring extreme conditions, Incoloy 800 series alloys are employed for stud bolts and other fasteners found on airborne components engines, gas turbines and propulsion systems.
Heat treatment: The outstanding high-temperature characteristics of Incoloy 800 series alloys render them fitting for heat treatment equipment like furnaces, annealing machines and heat exchangers. Stud bolts made of these alloys face raised heat in such uses. They are also able to endure thermal cycling.
Chemical applications: Studbolts fabricated from Incoloy 800 series alloys serve in a range of chemical uses, including forming acids, alkalis and other corrosive substances. Their resistance to corrosion and oxidation makes them well suited to the vessels, reactors, and piping systems of chemical plants.
Understand the difference: Incoloy 800, 800H, and 800HT are versions of the same alloy that differ slightly in their composition and characteristics. Incoloy 800H contains more carbon, whereas 800HT offers superior creep-rupture properties. Identify the option that best fits your requirements according to factors like temperature, pressure, and environmental conditions.
Define application requirements: Specify the operating parameters such as temperature, pressure, corrosion resistance, and resistance to oxidation or sulfur-bearing atmospheres. Doing so will assist you in selecting the appropriate Incoloy stud bolts.
Refer to standards and specifications: To confirm that performance and design requirements are met, consult industry standards and specifications like ASTM, ASME, and ANSI. These standards direct composition, devices, and design.
Consider corrosion resistance: Incoloy 800 series alloys are recognized for outstanding corrosion resistance across many environments, including acidic and high-temperature settings. Review the particular corrosion challenges in your application and confirm that the stud bolts you select deliver sufficient energy.
Check mechanical properties: Examine mechanical properties like tensile strength, yield strength, and stiffness to confirm the stud bolts can handle application loads and service conditions without failing.
