Known for its dedication to precision, durability, and reliability, MERIH STAINLESS serves a variety of industrial sectors that need strong fastening solutions. With state-of-the-art production facilities and rigorous quality control measures, the company guarantees that each stud bolt meets international standards and customer requirements. Designed to resist corrosion, withstand heat, and provide exceptional mechanical strength, MERIH STAINLESS’s 347 Stud Bolts are built to perform reliably even in the toughest conditions, making them a preferred choice around the globe.
These Stainless Steel 347 Stud Bolts are mainly made up of iron, with 17–19% chromium, 9–13% nickel, and a touch of niobium, which boosts their resistance to intergranular corrosion. They usually have a tensile strength ranging from 700–850 MPa, a yield strength of 450–550 MPa, and an elongation of about 30%, depending on their size and manufacturing standards. This material excels in resisting high-temperature oxidation, stress corrosion cracking, and pitting, making it perfect for harsh environments. The niobium-stabilized composition ensures that the bolts maintain their structural integrity even when exposed to heat for extended periods, keeping both their mechanical performance and corrosion resistance intact.
