Brian Fasteners is a Houston, USA-based leading manufacturer and supplier of high-performance industrial fasteners specializing in ASTM A 453 GR 660 Class C Bolts. Focused on precision engineering and quality, Brian Fasteners caters to industries in energy, petrochemical, and power generation. The bolts are constructed to operate at high pressure and temperature, making them perfect for challenging applications. Renowned for uninterrupted quality, punctual delivery, and tailored solutions, Brian Fasteners has established itself as a company that can be relied upon and trusted, servicing both indigenous and foreign markets with better fastening solutions and technical support.
ASTM A 453 GR 660 Class C Bolts are fabricated from iron-based superalloy consisting mainly of Nickel (24-27%), Chromium (13-17%), Molybdenum (1.0-1.5%), Titanium (1.9-2.35%), and balanced with Iron. These bolts have outstanding mechanical characteristics, with a minimum of 895 MPa tensile strength and 585 MPa yield strength. They provide outstanding resistance against oxidation and stress corrosion cracking. The bolts retain mechanical strength at temperatures of up to 704°C (1300°F), which makes them particularly ideal for high-temperature, high-stress environments, particularly where continuous load and corrosion resistance are of primary concern.
