As a company that manufactures wire for numerous industries, having a range of alloys that are specifically catered to prevent corrosion is crucial to ensure our customers can find exactly what they need. First, it’s important to understand why metals can corrode.
Metals can corrode for numerous reasons, especially in harsh conditions. Examples of typical metal corrosions include metal reacting with a substance like oxygen, or a metal being placed under too much stress causing the material to crack.
At CWI we have the corrosion resistant metal alloys you need to ensure long-lasting performance even in the harshest of conditions. Our research and years of manufacturing experience promise materials that can withstand corrosive environments.
Today’s Challenges
As industries around the world push for higher and higher levels of performance in their materials, metallurgists continue to develop new and exciting alloys to meet today’s challenges. Regardless of the environment, strain, or temperature that today’s specialty metals need to operate in, there are choices available to engineer a range of solutions in a variety of applications.
Combining the global resources of the Central Wire Group of Companies, with our Metallurgical knowledge and manufacturing experience, we can provide the highest quality solutions, including the right alloy for your application every time.

Our Corrosion Resistant Metals
Corrosion resistance in a stainless steel or nickel alloy can provide superior performance and extend the working life of a product. Here come are suggested alloys for harsh environments, along with their chemical compositions.
Basic Austenitic Stainless Steel
304
CWI 304 [ UNS: S30400 / EURO: 1.4301 ] is a basic, austenitic stainless steel containing a minimum of 18% chromium and 8% nickel. This material meets the chemistry of the ASTM A580 specification.
316
CWI Series Stainless 316 is an austenitic chromium-nickel-molybdenum stainless steel with good general corrosion resistance and improved pitting resistance.
UNS S31600 – Cr: 16.0-18.0%, Ni: 10.0 – 14.0%, Mo: 2.0-3.0% with full chemistry to ASTM A580
Duplex Stainless Steel
GEN 2209 is a filler material designed to weld duplex stainless steels such as UNS Number N31803. The welds are characterized by high tensile strength and improved resistance to stress corrosion cracking and pitting.
GEN 2594 provides matching chemistry and mechanical property characteristics to wrought superduplex alloys such as 2507 and Zeron 100, as well as to superduplex casting alloys (ASTM A890). Its structure results in high tensile/yield strength and superior resistance to SCC and pitting corrosion.
Advanced Austenitic Stainless Steel
904L
CWI Hi-Strength Series Stainless 904L is a low carbon, high alloy austenitic stainless steel designed for moderate to high corrosion resistance in a wide range of process environments.
UNS N08904 – Cr: 19.0%-23.0%, Mo: 4.0-5.0%, Ni: 23.0-28.0%, CU: 1.0-2.0%
Nickel-Based Alloys
CWI Nickel Specialty Series Inconel 625 is a nickel-based alloy used for its high strength as well as outstanding corrosion resistance.
UNS N06625 – Cr: 20.0-23.0%, Mo: 8.0-1.0% Ni: 58.0% min and Cb: 3.15-4.15%
CWI Nickel Specialty Series Inconel 825 is an austenitic nickel-iron-chromium alloy with addition of molybdenum and copper. It has excellent resistance to both reducing and oxidizing environments. UNS N08825 – Cr: 19.5-23.5%, Cu: 1.5-3.0%, Mo: 2.5-3.5%, Ni: 38.0-46.0% and Fe: Balance with full chemistry to ASTM B425
CWI Specialty Series Alloy X750 is a precipitation hardenable nickel-chromium alloy used for its corrosion and oxidation resistance at temperatures to 1300°F (704°C).
UNS N07750 – Al: 0.40-1.0%, Cb: 0.70-1.20%, Cr: 14.0-17.0%, Fe: 5.0-9.0%, Ni: 70% min and Ti: 2.25-2.75% with full chemistry to AMS 5698
CWI Nickel Prime Series C276 is a solid-solution-strengthened, nickel-molybdenum-chromium alloy with a small amount of tungsten, which exhibits excellent corrosion resistance in a wide range of aggressive environments.
UNS N10276 – Cr: 14.5-16.5%, Fe: 4.0-7.0, Mo: 15.0-17.0% and balance Nickel, per ASTM B574
CWI Nickel Prime Series MP35N®* is a multi-phase, nickel-cobalt based alloy that has a unique combination of ultrahigh tensile strength, good toughness and excellent corrosion resistance.
UNS R30035 – Cr: 19.0-21.0%, Mo: 9.0-10.5%, Ni: 33.0-37.0% and Co: Balance per AMS 5844
