High Harden 17-4PH Stainless Steel Round Tube Forged Steel Pipe Bright Polished SS Pipe

17-4 - UNS S17400:

Type 17-4 is the most common grade of martensitic precipitation hardenable (PH) alloys. 17-4 provides an outstanding combination of high strength, good mechanical properties at temperatures up to 600°F (316°C), and short-duration, low-temperature heat treatments that minimize warpage and scaling. Its good corrosion resistance, formability and weldability make it ideal for a variety of applications in aerospace, petrochemical, and other structural applications. In the annealed condition 17-4 maintains high mechanical properties making some forming operations difficult.

Heat Treatments:

17-4 is typically supplied in Condition A, and can be heat treated at a variety of temperatures and times to achieve a wide range of properties. Below is a sampling of standard heat treatments for Condition A 17-4 material:

Corrosion Resistance:

Type 17-4 PH stainless steel withstands corrosive attack better than any of the standard hardenable (martensitic) stainless steels and is comparable to Type 304 in most media. The alloy exposed to seacoast atmosphere will gradually develop overall light rusting and pitting in all heat-treated conditions. In common with other stainless steels, 17-4 material is subject to crevice attack if exposed to stagnant seawater for any length of time.
