17 4 PH is a widely used age-hardening steel. It has an excellent combination of hardness, high strength, and resistance to corrosion.

17-4PH is a chromium-copper steel that is used for applications and environments which require corrosion resistance and high strength. It has excellent quality factors such as hardness, high strength, and corrosion resistance. 

We offer various finishing services for your precision bars, including polishing, chamfering, and packaging

17-4PH Properties & Applications

To manipulate good strength and toughness we heat treat 17-4PH to H900, H925, H1025, H1050, H1150.

This stainless steel grade is a versatile and readily weldable, machinable, and formable. However, a solution treated condition is not applicable for 17 4PH steels. Its fabrication techniques are quite similar to those established for regular stainless steel grades. 17-4PH forges easily and has exceptional welding characteristics. What makes this grade applicable to a vast range of uses is the combination of good mechanical and processing properties that play an advantageous role in many industries.


Advance Grinding Services stocks 17-4 PH stainless steel round bars for use in high resistance and high strength environments. They are also perfect for applications that require high resistance to galling, high fatigue strength, resistance to seizing and stress corrosion. 17-4PH is suitable for intricately manufactured parts which require extensive welding and machining, or where there exists a problem like distortion in conventional heat treatment. 17-4PH corrosion resistance is superior to that straight chromium grades like 416. Its surface finish and an aging heat treatment can affect corrosion resistant properties.


The martensitic steel is a composition of chromium, nickel, and copper. The elements are in percentages of Cr- 16%, Ni- 4% and Cu- 4%. 17-4PH round steel bars are also known as UNS 17400.
