Fajar Nickel Alloys is a reliable producer and supplier of premium Super Duplex Steel Slitting Coils in Jakarta, Indonesia. We are known for engineering superiority and customer-centric service, delivering corrosion-resistant and high-strength materials to industries like oil and gas, construction, and marine engineering. Our Super Duplex Steel Slitting Coils are made to withstand the toughest conditions, providing unequalled durability and reliability. With dedication to accuracy, quick turnaround, and technical superiority, Fajar Nickel Alloys provides customers throughout Indonesia and worldwide with superior materials engineered to meet the most demanding performance and quality requirements.
Super Duplex Steel Slitting Coils are manufactured from a specially formulated blend consisting of 22–25% chromium, 4–7% nickel, 3–5% molybdenum, and minute traces of nitrogen, manganese, and copper. These grades provide excellent corrosion resistance as well as chloride-induced stress corrosion cracking resistance. The mechanical strengths are also superb, with tensile strengths between 680 and 800 MPa and yield strengths between 450 and 550 MPa. High impact toughness and fatigue strength are also observed in these coils, suitable for applications that involve resistance to pitting, crevice corrosion, and mechanical stress in severe conditions.

Super Duplex Steel Slitting Coils are employed in severe applications requiring extreme strength as well as exceptional resistance to corrosion. For offshore platforms, pressure vessels, and pipelines subjected to seawater and aggressive chemicals in the oil and gas sector, they are the perfect choice. They are employed in structural supports and reinforcement in corrosive conditions in the construction industry. Marine engineering utilizes them as a critical component in shipbuilding parts and ballast water systems. Their high formability and good weldability also make them appropriate for heat exchanger fabrication, tanks, and process equipment. The coils are capable of long-term performance, lower maintenance, and high reliability under harsh operating conditions.
