15-5 PH stainless steel - 1.4545 - Available from stock
The 1.4545 alloy, known commercially as 15-5PH or by the X5CrNiCu15-5 standard/UNS S15500, is a type of martensitic precipitation hardening (PH) stainless steel. It is designed to combine high strength, good corrosion resistance and excellent mechanical properties, even at temperatures of up to 316°C.
Technical summary of this steel:
- Europe: 1.4545 | X5CrNiCu15-5
- USA: 15-5PH | UNS S15500
- Europe : EN 3364 | EN 3479 | EN 4842 | NF EN 2815
- USA: AMS 5658 | AMS 5659 | ASTM A564 | AMS 5862 | AMS 5562
- High strength & sturdiness: thanks to its precipitation hardening, this alloy offers high mechanical strength, and is very robust.
- With better corrosion resistance compared to other martensitic steels, the 15-5PH is suitable for use in slightly corrosive environments.
- Excellent mechanical properties at high temperatures: maintains good mechanical properties up to 316°C, an advantage in high-temperature applications.
- The precipitation hardening heat treatment process usually involves heating the alloy to a medium temperature (about 1040°C/ 1904°F) before quickly letting it cool, then reheating it to a lower temperature (between 480°C-620°C /896°F-1148°F) to begin the hardening phase.
