Jyoti Steels, based in Mumbai, India, is a leading producer and supplier of superior performance Incoloy 825 Bolts, which are extremely resistant to corrosion and long-lasting in harsh environments. With its emphasis on quality and precision engineering, Jyoti Steels offers Incoloy 825 bolts that comply with international standards and are suitable for use in chemical processing, marine, and high-temperature industrial applications. These bolts are relied upon for their extended service life, high mechanical strength, and capacity to work well under tough operating conditions that include acids, heat, and pressure.
Incoloy 825 Bolts consist of Nickel (38–46%), Iron (min 22%), Chromium (19.5–23.5%), Molybdenum (2.5–3.5%), Copper (1.5–3%), and Titanium (0.6–1.2%), with minor levels of Carbon (max 0.05%) and Manganese (max 1%). These bolts contain good mechanical properties, such as 690 MPa tensile strength, 275 MPa yield strength, and 30% elongation. Their physical properties are 8.14 g/cm³ density and a melting point of about 1370°C. They exhibit great resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking in both acidic and marine environments.
