With a strong focus on quality, innovation, and customer satisfaction, Ojas provides stainless steel solutions that adhere to the rigorous standards of the aerospace, chemical, and engineering industries. The 17-7 PH alloy is precipitation-hardened, making it perfect for applications that demand high mechanical strength and dimensional stability. Ojas Pipes and Tubes utilizes cutting-edge manufacturing techniques to create durable, precisely engineered pipes designed for critical applications in challenging environments.
Stainless Steel 17-7 PH Pipes generally consist of 17% chromium, 7% nickel, 1% aluminum, along with small amounts of manganese, silicon, and carbon. This alloy achieves its impressive mechanical properties through a combination of heat treatment and precipitation hardening. It boasts a tensile strength of up to 1170 MPa and a yield strength of around 1035 MPa, while also offering good ductility and toughness. The alloy excels in resisting corrosion, oxidation, and fatigue, even under dynamic conditions. Additionally, 17-7 PH maintains its high strength and performance across a wide temperature range, making it an excellent choice for high-stress and high-fatigue environments.
