Stainless steel alloys with the term PH in their name indicate that they are precipitation hardened alloys. Typically a precipitation hardening or PH stainless steel alloy such as 15-5 Ph Rod is known to have high resistance to corrosion. It is not unusual for PH alloys to be heat treated in order to increase the tensile strengths of these alloys between the range of 850 MPa to 1700 MPa and yield strengths of 520 MPA to more than 1500 MPa.
In the case of the UNS S15500 Square And Cold Finished Bar, different heat treatments will yield different tensile strengths. However, the tensile strength values for each heat treatment carried out on the alloy would result in the AMS 5659 15-5PH Bright/ Flat Bar exhibiting tensile strength as high as in the range of 792 MPa - 1310 MPa. Since PH alloy exhibits properties such as high strength, corrosion resistance, the DIN 1.4545 Hex Bars are used in industries such as oil and gas, nuclear, and aerospace industries.
The name of this alloy is a derivative of the type of alloy it is as well as the content of 15% Chromium and 5% Nickel added in the 15-5ph Stainless Steel Round Bar. Another benefit of using the alloy is that it is readily weldable and it is possible to machine the 15-5 PH Round Bar, using any heat conditions suited to this grade including the following treatments H900, H925, H1025, H1075, H1100, H1150, Double H1150 & H1150M .
