What is 17-4 PH condition a hardness?
17-4 PH is a martensitic precipitation hardening (age hardening) stainless steel that can provide both high strength and excellent corrosion resistance. In the annealed (solution treated condition- Condition A) the density of this material is 0.280 lb/in^3. H 900 density is 0.282 lb/in^3.
Is 17-4 PH stainless steel magnetic?
17-4 stainless steel, otherwise known as SAE Type 630 is frequently used with operations demanding high tensile strength and a middling level of corrosion resistance. 17-4 PH is the most used grade of martensitic precipitation hardenable alloys. Just as all martensitic metals, 17-4 is magnetic.
How do you heat treat 17-4 SS?
The recommended heat-treatment of 17-4 PH stainless steel is as follows: Solution treatment is performed at 1040 °C for 1 h followed by water quenching. subsequently, aging could be conducted at low temperatures followed by air cooling to enhance precipitation and the relevant mechanical properties.
Does 17-4 PH Harden?
In the hardened condition 17-4 will not work harden significantly. I presume that you heat treat first since you need tighter dimensional tolerance than you can get with post-machining heat treatment.
What kind of stainless steel is 17-4?
17-4 stainless steel. SAE type 630 stainless steel (more commonly known as 17-4; also known as UNS 17400) is a grade of martensitic precipitation-hardened stainless steel. It contains approximately 15–17.5% (17) chromium and 3–5% (4) nickel, as well as 3–5% copper.
What are the uses of 17-4 corrosion resistance?
Uses for 17-4 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 kind of heat treatment is alloy 17-4PH?
It is magnetic. Heat Treatment Alloy 17-4PH is provided in the solution-annealed condition (Condition A). Mechanical properties may be altered by subsequent age hardening treatments. These aging treatments are referred to as Conditions H900, H1025, H1075, H1150, H1150M and H1150D.
Is the sus630 stainless steel the same as 17-4?
SUS630 is the same as 17-4PH, and they are both refer to the same grade. 17-4 can be heat treated to high levels of strength and hardness, and features corrosion resistance and machinability comparable to austenitic 304 stainless.
