Type 17-7PH® Precipitation Hardening Alloy is a semi-austenitic stainless steel which is austenitic in the annealed condition, but martensitic in the hardened condition. Type 17-7PH® provides high strength and hardness, excellent fatigue properties, good corrosion resistance and minimum distortion upon heat treatment.
What are the physical properties of 17 7PH stainless steel?
Stainless steel grade 17-7 PH is a precipitation hardened stainless steel that possesses high strength and hardness, excellent fatigue properties, good formability, good corrosion resistance, and minimal distortion upon heat treatment. The properties of this alloy are well suited for aerospace applications.
What is the chemical composition of 17 7PH stainless steel?
17-7 PH Composition The chemical composition of 17-7 breaks down as follows: Chromium: between 16.0 and 18.0 percent. Nickel: between 6.50 and 7.75 percent. Aluminum: between 0.75 and 1.50 percent.
Is 17 7PH stainless steel magnetic?
Type 17-7 PH is a Chromium-Nickel-Aluminum, austenitic stainless steel. It is the most formable of all PH grades and has the highest strength and hardness. It is less magnetic than other PH grades and offers minimal distortion upon heat treatment.
What does PH stand for in stainless steel?
PH stainless steels are a group of alloys that are resistant to the effects of corrosion. To increase their yield strength, these alloys are subjected to heat treatment during precipitation hardening (PH) or age hardening. You must be wondering what all these terminologies mean.
What is ASTM A313?
ASTM A313 Stainless Steel Wire Wire can be made as round or flat ribbon and finished in a variety of tempers. This specification covers austenitic, austenitic-ferritic, and age-hardenable stainless steel round spring wire intended especially for the manufacture of springs.
How do you heat treat 17-7 stainless steel?
ATI 17-7 precipitation hardening alloy is furnished as plate, sheet and strip from ATI. In all forms, the material is furnished in the annealed condition. In strip form, the material may be provided in a cold rolled condition suitable for direct precipitation hardening heat treatment at 900°F (482°C).
What is the hardness of 17 4 PH?
17-4 PH Stainless Steel Properties
| Condition | Ultimate Tensile Strength (PSI) | Hardness Rockwell |
|---|---|---|
| H900 | 190,000 | C40 |
| H1025 | 155,000 | C35 |
| H1075 | 145,000 | C32 |
| H1150 | 135,000 | C28 |
Does 17-4 PH Harden?
In the hardened condition 17-4 will not work harden significantly. I presume that you heat treat first since you need tighter dimensional tolerance than you can get with post-machining heat treatment.
What is 17-7PH steel sheet?
