Yousef Steel, a prominent manufacturer and supplier located in Riyadh, Saudi Arabia, specializes in high-quality **15Mo3 pipes** that are extensively utilized in pressure vessels, boilers, and heat exchangers designed for high-temperature operations. This chromium-molybdenum alloy steel, known as 15Mo3, is celebrated for its remarkable creep resistance, excellent weldability, and outstanding mechanical properties when exposed to elevated temperatures. At Yousef Steel, we prioritize precision in manufacturing and uphold rigorous quality control measures to comply with both domestic and international standards, ensuring that our pipes are reliable for critical industrial applications.
Typically, 15Mo3 pipes consist of approximately 0.15% carbon, 0.30% molybdenum, along with trace elements of chromium and manganese, all of which contribute to enhanced strength, corrosion resistance, and stability at high temperatures. These pipes are designed to provide impressive tensile strength, impact toughness, and resistance to oxidation and carburization under elevated conditions. They can be produced as seamless or welded pipes and are often delivered in normalized or normalized and tempered states to boost their mechanical performance.
