MERIH STAINLESS, based in Istanbul, Turkey, is a reliable producer and supplier of high-performance Stainless Steel 253MA Pipe Fittings. With a focus on heat- and corrosion-resistant stainless steel products, MERIH STAINLESS supplies mission-critical industries like petrochemical, power generation, and thermal processing. Their 253MA pipe fittings are designed for high-temperature strength and oxidation resistance to ensure durability in severe service conditions. Merih Stainless, a company known for quality, accuracy, and timely delivery, serves stringent global markets with reliable and efficient solutions for high-stress, high-temperature piping systems.
Stainless Steel 253MA Pipe Fittings are high-temperature austenitic stainless steels with superior oxidation resistance and mechanical strength. Chemical composition consists of Chromium (20–22%), Nickel (10–12%), Silicon (~1.4–2.0%), and rare earth metals for improved oxidation resistance. These fittings have a minimum tensile strength of 600 MPa, yield strength of 310 MPa, and outstanding creep resistance. 253MA is specially designed to work in conditions up to 1100°C (2012°F), delivering an outstanding combination of heat resistance, strength, and thermal cycling stability in structure.
