1.4542 P1070 is a precipitation hardening stainless steel condition commonly specified when high strength, corrosion resistance, and reliable mechanical performance are required.
The material is the European designation for 17-4 PH stainless steel and is widely used throughout aerospace, medical, energy, and industrial manufacturing sectors.
What Is 1.4542 P1070?
1.4542 is the EN designation for 17-4 PH stainless steel.
P1070 refers to a mechanical property condition providing approximately 1070 MPa minimum yield strength.
Equivalent designations may include:
- 17-4 PH Stainless Steel
- AMS 5643
- UNS S17400
- X5CrNiCuNb16-4
Why Engineers Specify 1.4542 P1070
Manufacturers choose 1.4542 P1070 because it provides:
- High strength
- Excellent corrosion resistance
- Good machinability
- Reliable dimensional stability
- Heat treatment capability
