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 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.
What is 17-7 PH?
17-7 PH® is a chromium-nickel-aluminum precipitation hardening stainless steel that provides high strength and hardness and a moderate level of corrosion resistance up to 600˚F.
What type of stainless steel is 17 4 PH?
hardening martensitic 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.
Does 17 4PH 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.
Does 17-4 PH Harden?
How do you precipitation hardened stainless steel?
A typical cycle might consist of heating to very high temperatures, 995°C (1750°F); cooling to -75°C (100°F) to effect the transformation to a martensitic structure; holding for three to eight hours, then precipitation-hardening between 450 and 565°C (840 and 1050°F) for 60 to 90 minutes; followed by air cooling.
How big is a 17-7 stainless steel plate?
All of our 17-7 PH stainless steel and stainless steel plate is ordered to specific thickness. We supply 17-7 PH stainless steel and 17-7 PH stainless steel plate and are capable of fulfilling your required lengths and widths.
What makes stainless steel 17-7PH so good?
17-7PH Stainless Steel is a semi-austenitic precipitation hardening steel with high levels of Chromium and Nickel. It is characterized by high strength and hardness, excellent fatigue properties, minimal distortion upon heat treatment, good formability in the annealed condition, and good corrosion resistance.
When do I need a 17-7 stainless steel weld filler?
Also, the austenite conditioning and precipitation hardening heat treatments are both required after welding to achieve high strength levels. When a weld filler is needed, 17-7 PH is most often specified. We supply 17-7 PH stainless steel and 17-7 PH stainless steel plate in various sizes and specifications.
