With state-of-the-art facilities and a strong focus on precision engineering, the company guarantees that every forging adheres to international standards for durability and performance. Known for their outstanding corrosion resistance, particularly against harsh acids, Stainless Steel 904L Forgings are built to endure tough environments. Mourad Metals is recognized for its reliability and innovation, catering to sectors like chemical processing, oil and gas, marine, and power generation with tailored solutions for demanding industrial applications.
Stainless Steel 904L Forgings are made up of high amounts of chromium, nickel, molybdenum, and copper, which give them remarkable resistance to both reducing and oxidizing acids. This super austenitic grade features a low carbon content, which helps reduce carbide precipitation and improves weldability. In terms of mechanical properties, 904L showcases excellent toughness, with a high tensile strength of about 490 MPa and a yield strength of 220 MPa, along with outstanding resistance to stress corrosion cracking. Its non-magnetic characteristics and ability to maintain strength under extreme conditions make it perfect for critical applications that require durability, reliability, and long-lasting performance in aggressive environments.
