General Technical Specifications
Stainless steel 1.4598 (also known as X2CrNiMoCuS17-10-2) is a high-quality alloy corrosion-resistant steel with unique mechanical and chemical properties. Thanks to the presence of chromium (Cr), nickel (Ni), molybdenum (Mo), copper (Cu), and sulfur (S) in its composition, the steel demonstrates excellent resistance to corrosion and aggressive environments. Unlike standard stainless steel grades, 1.4598 is designed for use in challenging conditions, including the chemical, oil, gas, food industries, and aggressive corrosive environments.
Stainless steel 1.4598 is highly suitable for mechanical processing and forming and has high resistance to intergranular corrosion. This makes it an ideal choice for industries where a combination of high strength and corrosion resistance is required.
Chemical Composition
