Al Summan Metals, a highly respected manufacturer and supplier located in Dubai, UAE, has built a solid reputation for providing top-quality corrosion-resistant materials, such as Alloy 20 Forgings. By placing strong focus on excellence, innovation, and precision, Al Summan Metals guarantees that its products meet international standards for strength, durability, and performance. The company caters to a broad spectrum of industries, such as chemical processing, pharmaceuticals, food production, and petrochemicals. Recognized for its technical expertise and dependability, Al Summan Metals reliably delivers Alloy 20 Forgings that provide outstanding resistance to acid attacks and perform exceptionally well in challenging environments.
Alloy 20 Forgings are composed mainly of nickel (32–38%), iron (35–45%), chromium (19–21%), along with modest amounts of molybdenum, copper, and niobium. This distinctive makeup provides exceptional resistance to sulfuric acid and to corrosion caused by chlorides. The alloy exhibits remarkable mechanical characteristics, delivering a tensile strength of 550–750 MPa and dependable ductility. Alloy 20 is also valued for its superb fabricability, weldability, and resistance to pitting and crevice corrosion, making it a perfect choice for applications in which both mechanical strength and corrosion resistance are critical.
