What type of stainless steel is 17 4PH?

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 difference between H1150 and HH1150?

HH1150 Condition A material heated 4 hours at 1150°F, air cooled, heated again for an additional 4 hours at 1150°F and air cooled. H1150-M Condition A material heated at 1400°F + 25°F for 2 hours, air cooled, then heated at 1150°F + 15°F for 4 hours and air cooled.

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.

Is 17-4 PH annealed?

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 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 type of stainless steel is 17-4 PH?

How hard is 17-4 PH stainless steel?

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.

Does 17 4PH work harden?
