MERIH STAINLESS, based in Istanbul, Turkey, stands out as a top manufacturer and supplier of premium stainless steel products, including the highly regarded Stainless Steel 348 Flanges. Renowned for their precision engineering and commitment to international standards, MERIH STAINLESS provides flanges that are both reliable and durable, perfect for critical industrial applications. With a strong emphasis on customer satisfaction, the company blends technical know-how with cutting-edge production techniques to cater to a variety of market demands. Their Stainless Steel 348 Flanges are particularly valued for their heat and corrosion resistance, making them a go-to choice in the petrochemical, power generation, and aerospace industries, both locally and around the world.
Stainless Steel 348 Flanges are made up of iron, chromium (17–20%), nickel (8–12%), and columbium (niobium), which enhances their resistance to intergranular corrosion. This stabilized austenitic stainless steel retains its strength and integrity even in high-temperature environments. The mechanical properties include a minimum tensile strength of 515 MPa, a minimum yield strength of 205 MPa, and an elongation of 35–40%. With a maximum Brinell hardness of 217, SS 348 flanges boast excellent weldability and toughness, even at cryogenic temperatures. Their superior thermal stability makes them perfect for applications that involve high pressure and heat.
