What is 17-4 Stainless Steel?2024-04-05T16:53:12+00:00

What’s up guys? Michael with Metals in a Minute. Today it’s 17-4, Type 630, or UNS S17400 …. Whatever you choose to call it …… it’s a precipitation hardenable corrosion resistant “stainless” steel alloy.

Heat treatment consists of two steps….
First is a “solution treatment” or “solution anneal” at 1900 deg F that is later followed by a
“precipitation” or “aging” heat treatment in the range of 900 to 1150 deg F.

The result is a combination of strength and corrosion resistance used in many applications.

Highest strength is achieved at 900 deg F and designated as H900.
Solution treatment is commonly performed at the producing mill and the precipitation treatment during the manufacture of the component part.

Common aerospace material specifications are:
AMS 5643 for bars, forgings, tubing, wire, and rings
AMS 5622 for premium quality bars, forgings,tubing, wire, and rings
AMS 5604 for sheet, strip, and plate

What is 13-8ph Stainless Steel?2024-04-05T18:23:32+00:00

13-8 or UNS S13800 …. Whichever name you choose to call it …… is a precipitation
hardenable corrosion resistant “stainless” steel alloy. In aerospace applications it is vacuum
melted and CEM remelted
Heat treatment consists of two steps….
First is a “solution treatment” or “solution anneal” at 1700 deg F that is later followed by a
“precipitation” or “aging” heat treatment in the range of 950 to 1150 deg F.
The result is a combination of strength and corrosion resistance used in many applications.
Highest strength is achieved at 950 deg F and designated as H950.
Solution treatment is commonly performed at the producing mill.
Common aerospace material specifications are:
AMS 5629 for bars, forgings, tubing, wire, and rings
AMS 5864 for plate

Don’t forget, check the specs. For more info check out our grade 13-8 stainless steel page.

What is Precipitation Hardening? Is Precipitation Hardening a Form of Heat Treating?2024-04-09T14:38:04+00:00

Precipitation hardening, aka age hardening in several common metal alloys requires a two step
heat treatment to develop the desired strength and hardness.
In the first step, the “solution treatment” or “solution anneal”; the alloy is heated to a
temperature at which the alloy constituents form a solid solution of the elements. Once the
desired distribution of elements is achieved, the alloy is cooled at a rate fast enough to inhibit
diffusion and suppress the formation of “precipitates”.
In the second step,the “precipitation” or “aging” treatment; the alloy is held at a temperature
where the rate of diffusion promotes the formation of the precipitates in the structure and results
in increased hardness and strength.
Age hardening alloys are found in steels, stainless steels, nickel alloys, and among aluminum
alloys.
