15-7 PH Round Bars Manufacturer, Stockist and Exporter

15-7 PH Round Bars are high-strength precipitation-hardened stainless steel bars known for their excellent corrosion resistance and mechanical properties. These bars are widely used in aerospace, medical, and industrial applications where reliability and durability are critical. They offer a combination of high toughness and superior fatigue resistance. With proper heat treatment, 15-7 PH stainless steel bars achieve optimal strength and hardness. These bars are available in various diameters and lengths to meet diverse engineering requirements. Their uniform microstructure ensures consistent performance across applications. 15-7 PH Round Bars are also valued for their resistance to stress corrosion cracking in harsh environments.

The chemical composition of 15-7 PH Round Bars includes elements like chromium, nickel, and aluminum, which contribute to its excellent mechanical properties. Chromium provides corrosion resistance, while nickel enhances toughness and ductility. Aluminum promotes precipitation hardening, which significantly increases strength after aging. Small amounts of carbon, manganese, and silicon are also present to improve hardness and machinability. This unique composition allows 15-7 PH Round Bars to perform well in both elevated and sub-zero temperatures. Proper processing ensures minimal internal stresses and high dimensional stability. Manufacturers maintain strict quality control to ensure bars meet international standards.

15-7 PH Round Bars exhibit remarkable mechanical properties, including high tensile strength and yield strength. Their hardness can reach up to 42 HRC after appropriate heat treatment. The bars also provide excellent elongation and impact resistance, making them suitable for critical structural components. Due to their precipitation-hardened nature, they retain strength without compromising toughness. These bars are often used in shafts, fittings, and aerospace components where fatigue resistance is essential. Surface finish can be polished or machined according to application requirements. Regular testing ensures the bars meet mechanical specifications consistently.
