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 atype 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 treatmentprocess usually involves heating the alloy to a medium temperature (about 1040°C/ 1904°F) before quickly letting itcool, then reheating it to a lower temperature (between 480°C-620°C /896°F-1148°F) to begin the hardening phase.
