A Corrosion-Resistant Alloy (CRA) is an alloy consisting of metals such as chrome, stainless steel, cobalt, nickel, iron, titanium, and molybdenum. When combined, such metals can promote corrosion resistance more than other components like carbon steel. This type of alloy offers reliable protection from corrosion, eradicating the need for expensive maintenance and repair.
Wrought Material that are Corrosion Resistant Alloys
Hastelloy® Alloy C-276 (UNS N10276) is known for its outstanding corrosion resistance in a wide range of severe media. The high nickel and molybdenum contents provide good corrosion resistance in reducing environments while chromium imparts resistance to oxidizing media.
Incoloy® Alloy 020 (UNS N08020) is an austenitic nickel-iron-chromium alloy with additions of copper and molybdenum. The nickel content makes Alloy 20 resistant to chloride-ion stress-corrosion cracking. Copper and molybdenum give resistance to reducing environments.
Alloy 625 Inconel® (UNS N06625) nickel-chromium alloy is used for its high-strength, excellent fabricability (including joining), and outstanding corrosion resistance. Service temperatures range from cryogenic to 1800°F. The strength of Inconel® Alloy 625 is derived from the stiffening effect of molybdenum and columbium on its nickel-chromium matrix; thus precipitation-hardening treatments are not required.
Inconel® Alloy 600 (UNS N06600): A super alloy with endless industrial applications. Alloy 600 is an excellent choice for a variety of applications. It is a high-resistance material to corrosion and heat, and its high thermal conductivity means that it has a low thermal expansion coefficient. These properties make it suitable for use in a range of applications.
