Super Duplex Round Rods have excellent properties with good resistance to stress corrosion cracking, general corrosion, pitting and high strength, approximately twice that of austenitic stainless steels. Stainless Steel Super Duplex Grade 2507 Has Been Designed To Handle Highly Corrosive Conditions And Situations Were High Tensile Strength Is Required. The Possesses Excellent Mechanical Properties. Which Is Why, Often A Light Gauge Of Grade 2507 Material, Can Be Used To Achieve The Same Design & Strength Of A Thicker Walled Nickel Alloy End Product.

Thinner cross sections of the Super Duplex 2507 Round Bar results in weight savings, which in turn can dramatically reduce the overall cost of fabrication and the end product.The high content of elements like molybdenum, chromium and nitrogen in the Super Duplex 2507 Bar aid the material withstand general corrosion like pitting and crevice corrosion. Since Super Duplex 2507 Round Bar is also resistant to acids and chlorine compounds, its applications can be seen in marine environments, especially in salt water containing chlorine compounds. The ferritic portion of the duplex structure of the Super Duplex 2507 Round Bar alloy makes them resistant to stress corrosion cracking in warm chloride containing environments.

Super Duplex 2507 Round Bar has excellent resistance to chloride stress corrosion cracking. Our super duplex steel bars (WNR 1.4410) are being developed and engineered in our infrastructure to international quality standards to the highest quality standards. 2507 Super Duplex Stainless Steel is highly resistant to chloride pitting, stress, crevice and general corrosion. Stainless Steel Super Duplex Grade 2507 Bar tolerates organic and inorganic acids well. All of these elastic properties make Super Duplex 2507 Round Bars useful in harsh environments and are commonly used in chemical and petrochemical engineering, paper facilities, and marine environments. Additionally, the 2507 Duplex Stainless Steel Bar is resistant to chloride related stress corrosion cracking, to corrosion fatigue, to erosion corrosion, to general corrosion in acids. Stainless steel grade 2507 alloy has good weldability, Low rate of thermal expansion, Good workability and very high mechanical strength. Although the Super Duplex 2507 Rods has a high tensile strength and good corrosion resistance, the applications of the alloy should be limited to temperatures below 600° F  or 316° C. Extended exposure of the Super Duplex 2507 Castings at elevated temperature can result in a reduction of both the toughness and corrosion resistance of alloy 2507.
