Stainless Steel 15-5 PH
Your guide to 15-5 PH Stainless Steel Machining
__________
Optimal combination of high strength and corrosion resistance
A modification of 17-4 PH
Reasonable machinability
15-5 PH has the high strength from martensitic grades of stainless steel (gained through heat treatment) and the corrosion resistance of austenitic grades.
This guide will take you through the main attributes, common applications, notes for designers and suitable finishing and treatments, as well as UK stock sizes and property tables. Don't forget to bookmark the page so you can refer back later.

What is 15-5 PH Stainless Steel?
15-5 PH is a modification of 17-4 PH, a precipitation hardening stainless steel with the optimal combination of the properties of martensitic and austenitic grades. It has the high strength from martensitic grades (gained through heat treatment) and the corrosion resistance of austenitic grades.
Heat treated conditions:
- Condition H900 (900°F)
- Condition H925 (925°F)
- Condition H1025 (1025°F)
- Condition H1075 (1075°F)
- Condition H1100 (1100°F)
- Condition H1150 (1150°F)
15-5 PH has reasonable machinability. It can be machined in the solution-annealed state or in final heat treated condition.
Industry Examples: Aerospace | Nuclear | Oil & Gas | Renewable energy | Food processing | Petrochemical | Marine
Typical Components & Applications: Gears | Valves | Shafts | Fitting & fasteners | Pump parts | Structural components | Engine parts | Instrumentation
Main Attributes:
- High strength after heat treatment
- Good corrosion resistance
- Good mechanical properties at temperatures up to 316°C
- Excellent mechanical properties
- Good welding characteristics
