Brian Fasteners offers high performance Hastelloy C22 Stud Bolts, known for their exceptional corrosion resistance and high temperature strength Made from advanced Hastelloy C22 alloy these stud bolts are designed to it can withstand harsh environmental conditions including the chemical and petrochemical industries their excellent strength and durability, making them ideal for critical applications where reliability is paramount. Each stud bolt is precisely engineered to meet stringent quality standards, ensuring high performance and durability in harsh conditions.
The corrosion-resistant alloy used to make Hastelloy C22 Stud Bolts is composed of roughly 56% nickel, 20–22.5% chromium, 12.5–14.5% molybdenum, 2–6% iron, and 2.5–3.5% tungsten. Outstanding resistance to oxidising and reducing chemicals is provided by this combination. With a tensile strength of about 690 MPa, yield strength of about 283 MPa, and elongation of up to 45%, the stud bolts have exceptional mechanical qualities. These fasteners are perfect for applications involving high mechanical stress and chemical exposure because they retain their integrity in high-pressure and high-temperature settings.
