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.
Is 17 4ph stainless steel austenitic?
The three types are: martensitic (e.g. 17-4 PH), semi-austenitic (e.g. 17-7 PH) and austenitic (e.g. A-286). Martensitic precipitation hardening stainless steels have a predominantly austenitic structure at annealing temperatures of around 1040 to 1065°C.
What is the difference between 303 and 316 stainless steel?
Type 316. Composed of slightly higher levels of chromium (16-18%) and nickel (10-14%) than types 303 and 304, the most distinguishable properties of 316 stainless steel come from the addition of 2-3% molybdenum, an element which significantly improves the alloy’s corrosion resistance.
What is 17 4 PH heat treated?
17–4 PH is a precipitation hardenable (PH) martensitic stainless steel, which is known for its combination of high strength and good corrosion resistance at elevated temperatures up to 350 °C.
