Jyoti Steels is a trustworthy manufacturer and exporter of Hastelloy C22 Stud Bolts from Mumbai, India. It is a specialized company that manufactures high-quality fasteners designed for application in extremely corrosive and aggressive environments. With a focus on precision, quality control, and compliance with international standards, Jyoti Steels provides long-lasting Hastelloy C22 Stud Bolts to several industrial sectors. Their materials are extensively used in applications where high resistance to corrosion and mechanical strength is necessary, and therefore they are the first choice of clients in the chemical, marine, and energy sectors.
Hastelloy C22 Stud Bolts consist of Nickel ~56%, Chromium 20–22.5%, Molybdenum 12.5–14.5%, Iron 2–6%, with other elements like Tungsten 2.5–3.5%, Cobalt <2.5%, and Carbon <0.015%. These bolts have a minimum tensile strength of 690 MPa, yield strength of 283 MPa, and elongation of about 45%. The density is 8.69 g/cm³, while the melting point is about 1399°C. These values make the bolts highly resistant to localized corrosion like pitting and crevice corrosion and stable and performing in both oxidizing and reducing environments.
