Alloy 17-4 PH round bar, also known as UNS S17400 is a precipitation-hardened martensitic stainless steel grade. Chromium, nickel, copper, and niobium are the main alloy components of 17-4 PH Stainless Steel Round Bars. As the name 17-4 PH round bar suggests that the chemical composition contains 17% chromium and 4% nickel. The alloy grade 17-4 PH h1150 round bar has high tensile strength, hardness, and corrosion resistance.

The 17-4 PH Stainless Steel Round Bar is considered to be a more affordable alloy than a number of high nickel alloys and non-ferrous alloys. Thus, industries like the petroleum and chemical industries are suitable for using this stainless steel alloy. These industries demand alloys that can perform effectively at temperatures up to 600 °F, such as the AMS 5643 Steel 17-4 PH Bright Bar. The bars could be given an age-hardening heat treatment to produce the best mechanical properties for the ss17-4ph material.
Even under these circumstances, the Stainless Steel 17-4 PH Flat Bar displays qualities like high strength, high hardness, and corrosion resistance. The SS round bars can thus be utilized in applications that require a combination of unusually high tensile strength qualities and moderately low magnetic properties. These SS 17-4 PH Cold Finished Bars are easily weldable and may be handled using standard shop fabrication techniques. The metal gains improved strength through heat treatment of the 17-4PH round bar at a temperature in the range of 900°F.
What are 17-4PH Round Bars?
SS 17-4PH Round Bars are a type of stainless steel round bars made of a precipitation-hardening alloy that contains 17% chromium, 4% nickel, and small amounts of copper and molybdenum. This particular alloy is known for its high strength & hardness. The "PH" in the name refers to the precipitation hardening process that it undergoes to achieve these properties.
Are 17-4PH Round Bars corrosion-resistant?
SS UNS S17400 Round Bars have a high level of corrosion resistance, particularly in environments that are high in chloride ions. The high chromium content provides excellent resistance to corrosion by forming a passive layer on the surface of the material, which prevents further corrosion. Additionally, the addition of nickel, copper, & molybdenum improves the corrosion resistance of the alloy.
What are the technical properties of 17-4PH SS Round Bars?
Stainless Steel 17-4PH Round Bars have a high tensile strength in the range of 180-220 ksi & high yield strength in the range of 150-190 ksi. These bars have many other properties including high hardness, and density, a low coefficient of thermal expansion, a high level of corrosion resistance, and are non-magnetic.
