17-4 ph is martensitic precipitation hardening stainless steel, which is widely used ss grade for different industrial application because it has a valuable combination of excellent strength & hardness with unmatchable corrosion resistance ability among all ss grades with different heat treatment temperature make 17-4 ph an outstanding choice among the other different grades. 17-4 ph a unique combination of properties makes this alloy an effective solution to many design and production problems.
17-4 ph Stainless Steel properties:
Physical Properties:
● Melting Range: 2560-2625°F (1404-1440°C)
● Density: 0.2820 lb/in³
Mechanical Properties:
Type 17-4PH stainless steel has excellent mechanical properties. For applications requiring high strength and hardness as well as corrosion resistance, Type 17-4PH stainless is an outstanding choice, and it is more cost-effective than many high nickel non-ferrous alloys.
