Stainless Steel 17-4 PH Rod
What is Stainless Steel 17-4 PH Rod
SS 17-4 PH round bar is an extensively utilised form of stainless steel in many industries due to its remarkable characteristics and adjustability. The “PH” in its name relates to “Precipitation Hardening,” a heat treatment method that boosts its power and hardness. This alloy exemplifies a balance of rust resistance, great strength, and superior mechanical capabilities, making it a preferred selection for numerous complex uses.
The SS 17-4 PH round bar stands out for its remarkable strength. It features high tensile and yield strength, which provide excellent protection against damage. This strength is achieved through the hardening process, which involves heating the material to a particular range of temperatures and cooling it.

In addition to its durability, SS 17-4 PH round bar offers corrosion protection. It offers protection against atmospheric and chemical corrosion, making it apt for use in tough conditions. This stainless steel blend contains chromium, nickel, and copper, which support its antirust characteristics. It can endure hostile substances like acids, alkalis, and chlorides, thus making it suitable for applications in the chemical and marine sectors.
A noteworthy characteristic of the SS 17-4 PH round bar is its ability to be machined and welded. Despite its superior strength, it can be processed using regular methods with the right tools.
This specific type of round bar (SS 17-4 PH) also has amazing robustness, which is important in uses requiring the ability to resist tension and shock. It can deal with cyclical loading and constant pressure without decreasing its mechanical properties. This makes it an appropriate option for elements subjected to pulsating and hefty conditions, such as toothed wheels, shafts, and structural components.


In addition, the SS 17-4 PH round bar is noted for its sturdy dimensions and capability to retain its shape and features even at varying temperatures. Its small coefficient of heat expansion ensures only minimal changes in proportions or curving during thermal changes. This important feature is appropriate for aerospace and precision engineering, where the dimensions and stability of components are necessary.
At Sumit Impex, we take great care in packaging SS 17-4 PH round bars to ensure their safe transportation and protection. Each bar is individually wrapped with a protective material, such as plastic or foam, to prevent any scratches or damage during transit. We then bundle the bars together securely, using sturdy packaging materials like wooden crates or cardboard boxes. Our packaging team pays meticulous attention to detail, ensuring that every shipment reaches our customers in perfect condition, ready for immediate use.
