15-5 PH Stainless Steel
1.4545 (15-5 PH)
- EN1.4545
- ENX5CrNiCu15-5
- UNSS15500
- Ticari15-5 PH
High-strength precipitation-hardening stainless steel covered by ASTM A564. Compared with 17-4 PH, 15-5 PH offers better mechanical properties and a cleaner structure. Magnetic, resistant to high temperatures, highly ductile and resistant to seawater.
01Applications
- Parts operating at high temperatures such as jet engines, gas turbines and reactors
- Marine, shipbuilding, water treatment plants and oil platforms
- Chemical industry
- Petrochemical industry
- Food industry
02Delivery Condition
- 35–42 HRC
03Heat Treatment
Typical values
- Solution treatment
- 1020–1060 °C, rapid cooling (air/oil)
- Hardness, solution treated (A)
- ≈ 33–36 HRC
- H900 / H950
- 482 / 510 °C, 1–4 h → maximum hardness
- H1025 / H1075
- 552 / 580 °C, 4 h → strength + toughness
- H1100 / H1150
- 593 / 621 °C, 4 h → maximum toughness and corrosion resistance
- Dimensional change
- ≈ −0.05…−0.1 % on ageing
