1.4418 stainless steel sheet is designed for superior corrosion resistance, particularly in environments exposed to acids, chlorides, and high temperatures. The addition of molybdenum enhances its resistance to pitting and crevice corrosion, especially in chloride-rich environments like seawater or chemical processing plants. It also offers excellent mechanical strength, toughness, and ductility, making it a versatile material for applications requiring both strength and corrosion resistance. Furthermore, 1.4418 provides excellent weldability, making it suitable for a wide range of fabrication techniques.
