Chanathip Nickel Alloys and Plates, located in the vibrant city of Bangkok, Thailand, has earned a solid reputation as a reliable manufacturer and supplier of top-notch Super Duplex Steel Forgings. These forgings are celebrated for their remarkable strength, durability, and resistance to corrosion, making them perfect for the rigorous demands of industries around the globe. With a keen eye on precision and adherence to international standards, Chanathip ensures that their forgings deliver dependable performance even in the harshest environments. The Super Duplex Steel Forgings they produce blend toughness with outstanding performance, making them ideal for critical applications in sectors like marine, oil & gas, chemical, and power generation, where safety and efficiency are absolutely essential.
These Super Duplex Steel Forgings are crafted from a well-balanced mix of chromium (about 24–26%), nickel (6–8%), molybdenum (3–5%), and nitrogen, which significantly boosts their resistance to pitting and crevice corrosion. They feature a duplex microstructure of austenite and ferrite, providing exceptional toughness and strength. On the mechanical side, they boast a tensile strength of around 800 MPa, a yield strength of about 550 MPa, and impressive impact resistance. Their high fatigue strength, hardness, and resistance to stress corrosion cracking make them well-suited for extreme operating conditions.
