17.4 PH stainless steel round bar is a type of precipitation-hardening stainless steel that contains 15-17% chromium, 3-5% nickel, 3-5% copper, and a minimum of 0.15% carbon. It is a high-strength material that offers good corrosion resistance and toughness.
Chemical Composition (in%):
C Max | Mn Max | P Max | S Max | Si Max | Cr | Ni | Mo | Other Element |
0.07 | 1.00 | 0.04 | 0.03 | 1.0 | 15.0/17.0 | 3.0-5.0 | --- | NB 0.15/0.45 |
17.4 PH stainless steel round bar is commonly used in applications such as aerospace, nuclear, and chemical industries that require high strength, corrosion resistance, and durability. It is also used in manufacturing of surgical instruments, golf club heads, and industrial equipment parts.
The precipitation-hardening process in 17.4 PH stainless steel round bar involves heating the material to a high temperature and then cooling it rapidly to form a supersaturated solid solution. It is then aged at a lower temperature to form the desired mechanical properties. This process results in a material that has high strength and hardness, as well as good corrosion resistance.
17.4 PH stainless steel round bar can be machined, welded, and polished, although it may require special techniques and tools due to its high hardness. It can also be heat-treated to improve its mechanical properties, such as strength and toughness.
Overall, 17.4 PH stainless steel round bar is a high-performance material that offers excellent strength, corrosion resistance, and durability, making it suitable for a wide range of industrial and commercial applications where these properties are critical.
