17-4 PH Round Bar Manufacturer, Supplier & Exporter in India
17-4 PH Round Bars from Astromet Steel & Engineering are precipitation-hardening stainless steels known for high strength and corrosion resistance. The alloy provides an excellent balance of mechanical properties and toughness. It maintains dimensional stability after heat treatment. This makes it ideal for precision components.
17-4 PH Round Bars offer high tensile and yield strength compared to conventional stainless steels. The alloy performs well in mildly corrosive environments. It also exhibits good fatigue and impact resistance. Heat treatment allows flexibility in achieving desired strength levels.
Astromet Steel & Engineering supplies 17-4 PH Round Bars in solution treated and aged conditions. Bars are manufactured with tight tolerances and smooth finishes. They are available in forged and cold drawn forms. Quality compliance ensures consistent performance.
The alloy is widely used where strength, corrosion resistance, and machinability are required. 17-4 PH Round Bars deliver long operational life. They are reliable under cyclic loads. This makes them suitable for structural and mechanical applications.
