They offer tailored forging solutions that meet international standards, serving both local and global clients. Their dedication to quality, timely delivery, and customer satisfaction has earned them a solid reputation in the specialty metals market. What sets Chuck Metals apart is their blend of innovation, technical know-how, and responsive service, all aimed at adapting to the ever-changing demands of the industry.
Alloy 20 Forgings are primarily made up of nickel (32–38%), chromium (19–21%), and iron, with added copper (3–4%), molybdenum (2–3%), and columbium (niobium). This unique composition gives them outstanding corrosion resistance, especially in sulfuric acid environments. The mechanical properties are impressive, featuring a tensile strength of about 80 ksi (550 MPa), yield strength of 35 ksi (240 MPa), and an elongation range of 30–40%. Alloy 20 also boasts good creep resistance and high toughness, making it ideal for challenging chemical and high-temperature settings where reliability is crucial.
