What is 15-5 stainless steel?
15-5 is a variant of the older 17-4 chromium-nickel-copper precipitation hardening stainless steel. Both alloys exhibit high strength and moderate corrosion resistance. High strength is maintained to approximately 600 degrees F. The 15-5 alloy was designed to have greater toughness than 17-4.
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. Strength and toughness desired can be manipulated by temperate range in the heat treatment process.
What is the PH of stainless steel?
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.
How do you heat treat 15-5?
Stainless steel-grade 15-5 can be heat treated in the following conditions:
- CONDITION A: Soak the material for 0.5 h at 1038°C (1900°F) and then cool the material in air.
- CONDITION H 900: The Condition A material is soaked for 1 h at 482°C (900°F) and cooled in air.
What is 17-4 stainless steel used for?
Uses for 17-4 stainless steel include components which require high hardness and/or corrosion resistance at temperatures of up to 600 °F (316 °C). Specific applications for 17-4 include the petroleum and chemical industries, as well as use in aircraft parts.
What is 17-4 pH condition A?
17-4 is a chromium-nickel-copper precipitation hardening stainless steel used for applications requiring high strength and moderate level of corrosion resistance….You’re currently reading page 1.

| Iron (Fe) | 69.91 – 78.85% |
Does pH affect stainless steel?
The effect of pH on the corrosion behavior of 316L stainless steel (SS) was investigated. The film resistance decreases and the corrosion current density increases as the pH rises from 6.42 to 7.52 for 316L SS. The corrosion rate of 316L SS increases with increasing pH in hydrogenated high temperature water at 300 °C.
What is the high strength of 17 4 PH stainless steel?
High strength is maintained to approximately 600°F (316°C).The 17-4 PH stainless steel alloy is martensitic in structure in the annealed condition and is further strengthened by a low temperature treatment which precipitates a copper containing phase in the alloy.
What is the difference between 17-4PH and 15-5 PH stainless steel?
Like the 17-4PH alloy, the 15-5 PH stainless steel alloy requires only a simple heat treatment; a one step process conducted at a temperature in the range 900°F (482°C) to 1150°F (621°C) depending on the combination of strength and toughness desired.
What is 15-5 pH 17-4 PH 4130?
In the series, 15-5 PH, 17-4 PH and 4130 are commonly utilized because of presence of chromium increasing the flexibility and durability. These are generally used in food handling as well as petrochemical sectors. Discussing the first alloy in series is 15-5 PH.
What is the best 15-5 or 17-4 PH for machining?
17-4PH is hard to beat. Not sure about 15-5 but it should be close. But it depends on the application. Put radii on the bottom of the grooves if possible. That’s if it’s being bent. Can you describe the loading and cycles?
