What is Condition C steel?
Processing: Condition C – heated to austenitic range, 1040°C (1900°F), and water quenched. Severely cold worked (60-70%). Corrosion Resistance: 17-7 PH is suitable for use in fresh water, industrial and marine atmospheres, and mild chemical and oxidizing environments.
What is 17 7PH stainless steel?
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.
Is 17-7 stainless steel martensitic?
17-7 PH Stainless Steel UNS S17700. 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.
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.
Is condition a the same as annealed?
Condition A is highly resistant to corrosion, making it useful in industries susceptible to this issue. It is an annealed metal, meaning it has gone through a heat treatment to make it more ductile and to give it that extra anticorrosive edge.
What is 17-4 PH condition A?
17-4 PH is a martensitic precipitation hardening (age hardening) stainless steel that can provide both high strength and excellent corrosion resistance. In the annealed (solution treated condition- Condition A) the density of this material is 0.280 lb/in^3.
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.
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 CH900 condition?
CH900 applies to 17-7 PH (Type 631) wire that has been previously solution annealed and then cold drawn, which is then aged for 1 hour at 900 °F (482 °C). If your article has not been cold drawn, then CH900 cannot be performed.
What type of stainless steel is 17 4 PH?
precipitation 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.
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 condition a 303 stainless steel?
303 is a free machining chromium-nickel austenitic stainless steel with good strength and good corrosion resistance, as supplied in the annealed condition with a typical brinell hardness of 190.
What does 17-7 mean on stainless steel?
* All Trademarks and/or Trade names are the properties of their respective owners. 17-7 Stainless Steel Sheet, 17-7 Stainless Steel Plate, 17-7 Stainless Steel Bar. 17-7 PH stainless steel is a precipitation-hardening stainless steel.
What is 17-7PH material?
Alloy 17-7 PH is extremely hard and strong in Condition C. Therefore, fabrication techniques for such materials must be used. Alloy 17-7PH is available in Sheet, Strip, Plate, Bars (Round Bars), Tube, Forgings and Welding Wire. 17-7PH Foil (Shim) is available in various thicknesses.
What is 17-7 PH steel used for?
Alloy 17-7 PH 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. Alloy 17-7 PH provides valuable property combinations particularly well suited for aerospace applications.
Is 17-7 pH hard or soft?
Formability In Condition A, Alloy 17-7 PH can be formed comparably to Type 301. It work hardens rapidly and may require intermediate annealing in deep drawing or in forming intricate parts. Spring-back is similar to that of Type 301. Alloy 17-7 PH is extremely hard and strong in Condition C.
