Stainless Steel 17-4 PH Round Bar is a precipitation-hardening martensitic stainless steel alloy known for its high strength, corrosion resistance, and hardness. The "17-4" refers to its composition, containing 17% chromium and 4% nickel, while "PH" stands for precipitation hardening, a heat treatment process that enhances its mechanical properties. It is widely used in aerospace, marine, chemical processing, and food industries due to its excellent strength and corrosion resistance.

Stainless Steel 17-4 PH Round Bars exhibit a unique combination of high tensile strength, superior corrosion resistance, and good toughness. They have a hardness that can be tailored through heat treatment, making them versatile for different industrial needs. This alloy retains its mechanical properties up to 600°F (316°C) and has excellent fatigue resistance, making it suitable for applications under stress and varying temperatures.

These round bars are commonly used in industries requiring high strength and corrosion resistance. Applications include aerospace components, turbine blades, nuclear reactor components, chemical processing equipment, food processing machinery, and medical devices. Their ability to maintain integrity in harsh environments makes them ideal for structural and mechanical parts exposed to corrosive elements.
