Merih Stainless, based in Istanbul, Turkey, is a reputable maker and provider of premium stainless steel products, such as Stainless Steel 13-8 PH Bars. Renowned for its provision of precision-engineered materials, Merih Stainless supplies bars that possess great mechanical properties coupled with excellent corrosion resistance. The company applies sophisticated manufacturing techniques and strict quality controls to assure its products conform to global standards. Merih Stainless Stainless Steel 13-8 PH Bars are manufactured for stringent applications requiring high strength, toughness, and durability and are supplied to industries like aerospace, automotive, and power generation in domestic as well as international markets.
Stainless Steel 13-8 PH Bars consist mainly of chromium (12.5–14.5%), nickel (7.5–8.5%), and copper (1.5–2.5%), with minor contents of niobium and aluminum to facilitate precipitation hardening. This alloy provides a distinctive combination of high tensile strength of up to 1400 MPa and excellent toughness. It has good corrosion resistance, particularly in mildly corrosive conditions. The material sustains its mechanical properties over a wide range of temperatures and shows excellent fatigue life, making it appropriate for high-stress structural elements.
