Merih Stainless, founded in Istanbul, Turkey, is a well-reputed manufacturer and supplier of stainless steel products of the highest quality, such as Stainless Steel 17-4 PH Coils. Renowned for its precision, strength, and reliability, Merih Stainless caters to an array of industries with products suitable for high-performance and long-term applications. With advanced manufacturing equipment and rigorous quality control processes, the company provides coil solutions of international standard. Merih Stainless 17-4 PH Coils are designed to exhibit superior mechanical properties, corrosion resistance, and consistent performance in extreme structural and industrial conditions.
Stainless Steel 17-4 PH Coils consist mainly of chromium (15–17.5%), nickel (3–5%), and copper (3–5%) with minor additions of niobium for precipitation hardening. This alloy provides a special combination of high strength, hardness, and moderate corrosion resistance. It can have tensile strengths of as much as 1100 MPa and yield strengths of around 1000 MPa through heat treatment. These coils have good mechanical properties even at high temperatures and are resistant to corrosion in atmospheric as well as mildly corrosive conditions. The material also has good dimensional stability and machinability.
