What is the PH of stainless steel?
17-4 PH
Stainless steel is an example of a common alloy used in the fabrication of many products. To further strengthen the stainless steel, they are subjected to heat treatments which result in the precipitation hardening stainless steel material. One of the most used types of PH stainless steel is 17-4 PH stainless steel.
How hard is 17-4 PH stainless steel?
17-4PH Stainless Steel High strength is maintained to approximately 600 degrees Fahrenheit (316 degrees Celsius). Alloy 17-4 PH 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.
What is the hardness of 17 4 pH?
Grade 17-4 stainless steel is the most widely used steel of the precipitation hardening grade steels. It has high toughness, strength, and corrosion resistance….Mechanical Properties.
| Properties | Metric | Imperial |
|---|---|---|
| Hardness, Brinell | 352 | 352 |
| Hardness, Knoop (estimated from Rockwell C) | 363 | 363 |
| Hardness, Rockwell C | 36 | 36 |
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.
What type of steel is 17-4?
17-4 stainless steel, also known as SAE Type 630, is a common and exceptionally durable type of steel used in a diverse variety of industries and applications. The numbers “17-4” refer to its composition: ≈17% chromium and ≈4% nickel. It also can include between 3 and 5% copper.
Can I heat treat this 17-4?

Is 17 4 material magnetic?
Type 17-4 PH provides an outstanding combination of high strength, good corrosion resistance, and good mechanical properties at temperatures up to 600°F (316°C). 17-4 PH has slightly more Ferrite than other PH grades, making it a bit more magnetic.
Is type 17-4PH stainless steel magnetic?
The 17-4 pH stainless steel is magnetic and less corrosion-resistant than 316L stainless steel. Standard 316L is slightly magnetic, but non-magnetic versions are available.
What is 17 – 4 steel?
The 17-4 stainless steel grade is an age-hardening martensitic alloy that combines high corrosion resistance and strength. Unlike conventional martensitic steels, it weldable by all standard methods, and achieves hardening with simple low-temperature treatment over a short period of time.
