| Element | 17-7PH |
|---|---|
| Chromium | 16.0-18.0 |
| Nickel | 6.5-7.7 |
| Manganese | 1.00 |
| Silicon | 1.00 |
Is 17 4ph a stainless steel?
17-4 PH Stainless Steel is a precipitation hardening martensitic stainless steel. Typical usage is seen in applications requiring high strength and a modest level of corrosion resistance.
What is 17 7PH stainless steel?
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 wire is used for stainless steel?
Stainless Steel Wire 316L This austenitic stainless steel wire adds Molybdenum for superior corrosion resistance and is used for permanent surgical implants.
What does the PH stand for in 17-4 PH?
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.
Does 17-4 PH work 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 type of steel is 17-7?
A stable, chromium-nickel-aluminum steel, 17-7 is a precipitation hardening steel with a high strength and moderately resistant to corrosion. In terms of corrosion resistance, 17-7 PH is comparable to 304 stainless steel and a better choice when compared to the 400 series of stainless steel.
What is 17 7ph stainless steel explain in detail with applications?
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.
Can you harden stainless steel wire?
All metals can be work hardened upon cold working, based on the type of stainless steel grade. However, like low alloy and carbon steels, martensitic stainless steels can be hardened by thermal treatments such as quenching and tempering. Cold working can harden ferritic stainless steels, like austenitic grades.
What are the properties of 17-7 PH stainless steel?
17-7 PH is a precipitation-hardening stainless steel that provides high strength and hardness, excellent fatigue properties, good corrosion resistance, good formability, and minimum distortion upon heat treatment. The alloy provides valuable property combinations particularly well suited for aerospace applications.
What kind of alloy is 17-7 pH?
Alloy 17-7 PH® precipitation hardening stainless steel alloy. It is a semi-austenitic being austenitic in the annealed condition and martensitic in the hardened condition. Alloy 17-7 PH® provides high strength and hardness, excellent fatigue properties, good corrosion resistance and minimum distortion upon heat treatment.
Which is the best type of stainless steel wire?
Type 17 chrome – 7 nickel stainless steel wire (AISI 631) has the corrosion resistance of Type 302 plus superior strength and heat resistance. This grade of stainless wire possesses high elastic qualities similar to music wire while maintaining the corrosion resistant qualities of the standard Type 302 stainless.
Which is the best material for spring wire?
The alloy is an excellent material for all kinds of springs where long life is required under severe service conditions, providing excellent fatigue properties, ductility, high yield strength, modulus of elasticity, and strength-to-weight ratio.
