Majid Fasteners employs cutting-edge production methods along with rigorous quality control to create products that are perfect for chemical, marine, petrochemical, and high-temperature applications. With a strong focus on durability, reliability, and keeping customers happy, the company delivers Stainless Steel 317/317L Stud Bolts that perform exceptionally well in harsh environments, supporting critical infrastructure across a variety of industries.
Stainless Steel 317/317L Stud Bolts are high-molybdenum austenitic fasteners designed to provide superior resistance to corrosion and pitting compared to standard 300-series grades. They include chromium, nickel, molybdenum, and a lower carbon content in the 317L variant, which enhances weldability and reduces carbide precipitation. On the mechanical side, these fasteners boast excellent tensile strength, good elongation, and stability even at elevated temperatures. Their austenitic structure contributes to their toughness and durability, ensuring they perform reliably in aggressive chemical settings, acidic environments, and chloride-rich conditions.
