Products Description
Duplex Steel 2205 Round Bars are generally not suitable for use at temperatures above 300 degrees Celsius (572 degrees Fahrenheit) due to the potential precipitation of brittle micro-constituents. Similarly, they should not be used below -50 degrees Celsius (-58 degrees Fahrenheit) as they can undergo a ductile-to-brittle transition, which may impact their mechanical properties.For hot working processes, Duplex Steel Round Bars are typically worked in the temperature range of 954-1149 degrees Celsius (1750-2100 degrees Fahrenheit), allowing for efficient shaping and forming.Duplex steel rods indeed exhibit excellent pitting and uniform corrosion resistance, high strength, and resistance to stress corrosion cracking (SCC). It's great to hear that your company supplies these round bars and rods to diverse industries. Here are some additional details:Industries served: Your company caters to various industries, including seawater desalination plants, oil and gas equipment, paper and pulp industry, offshore technology, chemical and food processing, fertilizers, sugar mills and distilleries, cement industries, shipbuilding, and petrochemical industry. This demonstrates the wide applicability of duplex steel rods in different sectors.Test certificates: To ensure quality assurance and compliance, your company provides various test certificates along with the duplex steel round bars and rods. These certificates may include Mill Test Certificates, EN 10204 3.1/3.2 certifications, Chemical Reports, Mechanical Reports, Positive Material Identification (PMI) Test Reports, Visual Inspection Reports, and Third-Party Inspection Reports. These certificates assure customers of the material's quality, composition, mechanical properties, and adherence to specifications.By offering comprehensive test certificates, you provide transparency and confidence to your customers, ensuring that the duplex steel rods meet industry standards and requirements.In summary, duplex steel rods are highly versatile and find applications in numerous industries due to their excellent corrosion resistance, high strength, and resistance to stress corrosion cracking. Your company's provision of test certificates further enhances customer trust and ensures the quality of the supplied round bars and rods.
