MERIH STAINLESS, based in Istanbul, Turkey, is a trusted name when it comes to manufacturing and supplying top-notch Stainless Steel 347 Bolts. These bolts are designed to perform exceptionally well in high-temperature and corrosive environments. Renowned for their strength, durability, and resistance to intergranular corrosion, they have earned the trust of industries around the globe. Crafted with advanced techniques and rigorous quality control, MERIH STAINLESS’s Stainless Steel 347 Bolts adhere to international standards for both performance and reliability. They are specifically engineered for secure fastening in demanding conditions, making them essential for critical applications in sectors like petrochemical, power generation, chemical processing, and aerospace, where stability and longevity are paramount.
Stainless Steel 347 Bolts are a type of stabilized austenitic stainless steel, containing 17–19% chromium and 9–13% nickel, along with small amounts of columbium (niobium) and tantalum to enhance stabilization. This special composition helps prevent carbide precipitation, boosting their resistance to intergranular corrosion at high temperatures. On the mechanical side, these bolts offer a tensile strength of about 515 MPa and a yield strength of 205 MPa, while also maintaining toughness even under high-temperature conditions. They showcase excellent creep and stress-rupture properties, along with good weldability and durability, making them ideal for extended use in corrosive and thermal environments.
