What is 17-4 PH condition A?
17-4PH combines high strength and hardness with good corrosion resistance. The alloy is furnished in the solution annealed condition (Condition A). It should not be used at temperatures above 572°F (300°C) or for cryogenic service.
What type of material is 17-4 PH?
SAE Type 630 stainless steel
SAE Type 630 stainless steel (more commonly known as 17-4 PH, or simply 17-4; also known as UNS S17400) is a grade of martensitic precipitation hardened stainless steel. It contains approximately 15–17.5% chromium and 3–5% nickel, as well as 3–5% copper.
Is 17-4PH stainless steel magnetic?
Its intense tensile strength keeps its ductility and hardness at temperatures at nearly 600°F, while still demonstrating exceptional corrosion resistance in all conditions offered by Premium Alloys. Just as all martensitic metals, 17-4 is magnetic.
What is the Rockwell hardness of 17-4 stainless steel?
The mechanical properties of annealed grade 17-4 stainless steel are displayed in the following table….Mechanical Properties.
| Properties | Metric | Imperial |
|---|---|---|
| Poisson’s ratio | 0.27-0.30 | 0.27-0.30 |
| Hardness, Brinell | 352 | 352 |
| Hardness, Knoop (estimated from Rockwell C) | 363 | 363 |
| Hardness, Rockwell C | 36 | 36 |
Can 17-4 PH be heat treated?
Alloy 17-4PH is a precipitation hardening martensitic stainless steel with Cu and Nb/Cb additions. The grade combines high strength, hardness (up to 572°F /300°C), and corrosion resistance. Mechanical properties can be optimized with heat treatment.
Will 17-4PH rust?
Such depths are associated with high pressure. The high strength of type 17-4 PH stainless steel makes it a great construction material for piping at such depths. Second, Type 17-4 PH alloy is resistant to corrosion both on and offshore.
How do you heat treat 17-4 PH stainless steel?
Age hardening of 17–4 PH usually consists of two steps: solution treatment followed by quenching and subsequent aging for precipitation hardening. For 17–4 PH, the solution treatment is done at 1050 °C for 30 min while the aging temperatures range from 480 °C to 760 °C with a duration of two to four hours.
Will 17 4PH rust?
Will 17-4 PH rust?
Using 17-4ph in medical instrumentation that get auto-claved, and rust is forming on surface. Parts were machined, heat treated, blasted and the passivated.
Can you heat treat 17-4 stainless steel?
The ATI 17-4™ precipitation hardening stainless steel is furnished in the annealed condition. This is also called the solution heat treated condition, or Condition A. Annealing is conducted by heat treating at approximately 1900°F (1040°C) to 1950°F (1065°C) and cooling to room temperature.
Is 17-4 PH annealed?
What is 17 4ph steel?
Specification Sheet: Alloy 17-4PH Alloy 17-4PH (UNS S17400), Type 630, is a chromium-nickel-copper precipitation-hardening martensitic stainless steel with an addition of niobium. 17-4PH combines high strength and hardness with good corrosion resistance. The alloy is furnished in the solution annealed condition (Condition A).
What is CH17 4 precipitation hardening?
17-4 Precipitation Hardening also known as Type 630 is a chromium-copper precipitation hardening stainless steel used for applications requiring high strength and a moderate level of corrosion resistance. High strength is maintained to approximately 600 degrees Fahrenheit (316 degrees Celsius).
What are the properties of 1717-4ph?
17-4PH combines high strength and hardness with good corrosion resistance. The alloy is furnished in the solution annealed condition (Condition A). It should not be used at temperatures above 572°F (300°C) or for cryogenic service.
What are the properties of 17-4PH?
These properties give designers the ability to add reliability to their products while simplifying fabrication and often reducing their costs. High strength is maintained to approximately 600°F (316°C). 17-4ph has good resistance to stress corrosion cracking at higher aging temperatures.
