Overview: This document provides detailed information on special
stainless steel wire rods produced by Aperam Alloys Imphy. It includes chemical compositions, standards, and main applications for various grades of stainless
steel.
Specifications: The document lists several grades of stainless steel, each with specific chemical compositions. Key elements include Carbon (C), Silicon (Si), Manganese (Mn), Nickel (Ni), Chromium (Cr), Molybdenum (Mo), Copper (Cu), Sulfur (S), Phosphorus (P), and Nitrogen (N). Each grade is associated with specific standards such as AWS, UNS, and EN numbers.
Procedures and Applications: Each stainless steel grade is designed for specific welding applications. For example, Phyweld® 309L Si is used for welding furnace and heating systems due to its oxidation resistance at high temperatures. Phyweld® 312 is suitable for duplex steel with high mechanical properties, offering good wear and corrosion resistance.
Norms and Standards: The document references various standards like AWS SFA 5.9 and UNS numbers, ensuring the materials meet industry requirements for welding and corrosion resistance.
Recommendations: The document suggests specific applications for each grade, such as Phyweld® 904LN for environments with sulfuric or phosphoric acid due to its superior corrosion resistance compared to AISI 316L.
Key Data from Tables: The tables provide detailed chemical compositions and applications for each grade. For instance, Phyweld® 25-9-4 is recommended for welding all duplex and super duplex steels where high corrosion resistance is required.
Critical Information: The document emphasizes the importance of selecting the appropriate stainless steel grade based on the specific environmental conditions and mechanical requirements. It highlights the enhanced properties of certain grades, such as improved corrosion resistance and mechanical strength.
