17-4ph or 17-4 Precipitation Hardening is a chromium-copper precipitation hardening steel that is used for applications and environments which require corrosion resistance and high strength. This stainless steel grade has combined excellent hardness, high strength, and corrosion resistance. To manipulate good strength and toughness by the temperature range within the heat treating process. This stainless steel PH grade is a versatile precipitation-hardening steel that is 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. Advance Grinding Services stocks 17-4PH Round Bars which are used where good resistance and high strength are required. They are also perfect for applications requiring good resistance to galling, high fatigue strength, and resistance to seizing and stress corrosion. 17-4PH is suitable for intricate parts which require extensive welding and machining, or where there exist a problem like distortion in conventional heat treatment. 17-4PH corrosion resistance is superior to that of hardenable straight chromium grades like 416. Its surface finish and an aging heat treatment can affect corrosion resistant properties.
