Jyoti Steels is a leading Hastelloy Nuts manufacturer and supplier company based in Mumbai, India. With decades of experience in high-performance alloy fasteners, the company supplies corrosion-resistant nuts designed for harsh industrial applications. Jyoti Steels supplies nuts to chemical processing, marine, oil & gas, and power generation industries. Their Hastelloy nuts are precision-designed, durable, and resistant to harsh environments. Made to international standards, these fasteners are suitable for fastening components that are subjected to aggressive chemicals, high pressure, and high temperatures under demanding operating conditions.
Chemical Composition, Physical and Mechanical Properties:
Hastelloy Nuts, particularly in C22 grade, consist of about 56% Nickel, 20–22.5% Chromium, 12.5–14.5% Molybdenum, 2–6% Iron, and 2.5–3.5% Tungsten, with incidental elements such as Cobalt (up to 2.5%) and Manganese (up to 0.5%). They provide a tensile strength of approximately 690 MPa, yield strength of 283 MPa, and elongation of 45%. The density of these nuts is 8.69 g/cm³, and they have a melting range of 1350°C to 1400°C. Due to their good resistance against pitting, crevice corrosion, and stress corrosion cracking, they are perfectly suited for both oxidizing and reducing environments.
