MERIH STAINLESS is a well-respected manufacturer and supplier located in Istanbul, Turkey, specializing in high-quality Stainless Steel 904L Flanges that are built to thrive in the toughest industrial settings. Renowned for their outstanding corrosion resistance, durability, and precision engineering, these flanges are crafted to meet international standards. They are particularly effective for connecting piping systems that encounter acids, chlorides, and high-stress conditions. With a commitment to cutting-edge technology, rigorous quality control, and global distribution, MERIH STAINLESS offers both standard and tailored flange solutions for industries like chemical processing, oil and gas, marine, pharmaceuticals, and power generation.
The Stainless Steel 904L Flanges from MERIH STAINLESS are crafted from a high-alloy austenitic stainless steel that includes chromium (19–23%), nickel (23–28%), molybdenum (4–5%), and copper (1–2%), all with an ultra-low carbon content (maximum 0.02%). This carefully balanced composition provides remarkable resistance to reducing acids, chloride pitting, and stress corrosion cracking. The flanges boast high tensile and yield strength, exceptional toughness, and structural stability even under extreme temperatures. Their non-magnetic properties and superior resistance to localized corrosion ensure they perform reliably, making them perfect for demanding industries where safety and dependability are crucial.
