Is 17-4 PH a stainless steel?

Is 17-4 PH a 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.

What does condition a mean for 17-4 stainless steel?

17-4 PH is a chromium-nickel grade of stainless that may be hardened by a single low temperature precipitation-hardening heat treatment. Excellent mechanical properties at a high strength level may be obtained by such treatment.

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.

What is the difference between 17-4 and 17-4 PH?

Type 17-4 PH provides an outstanding combination of high strength, good corrosion resistance, and good mechanical properties at temperatures up to 600°F (316°C). 17-4 PH has slightly more Ferrite than other PH grades, making it a bit more magnetic.

Does 17 4ph work 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.

How hard is h900?

It is one of the most widely used precipitation hardening grades, as it has high strength hardness up to about 572°F while demonstrating good corrosion resistance in all heat treated conditions. Its mechanical properties can be optimized with heat treatment where very high yield strength up to 180 ksi can be achieved.

Does 17-4 need to be heat treated?

The ATI 17-4™ precipitation hardening stainless steel is readily welded using conventional inert gas methods used for stainless grades. Preheating is not usually required. Postweld heat treating is needed to produce the various precipitation hardened heat treatment properties.

How hard is H1025?

It is one of the most widely used precipitation hardening grades, as it has high strength hardness up to about 572°F while demonstrating good corrosion resistance in all heat treated conditions….Machinability:

Heat Treated Condition H1025
-100 to 70°F
70 – 200°F 6.0 x 10-6
70 – 400°F 6.0 x 10-6
70 – 600°F 6.2 x 10-6

Does 17 4PH work harden?

Will 17 4PH rust?

The martensitic PH stainless grades like 17-4 and 15-5 will also rust. Note that Alloy 36 (36% NI, balance iron) will readily rust. It is not a stainless steel, since it has no chromium. These alloys are commonly delivered from the mill with a light rust or dark oxide on the surface.

Is 17 4PH 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.

What kind of stainless steel is 17-4?

Synopsis. 17-4 Stainless Steel (coming from the chemical makeup 17% chromium and 4% copper or UNS 17400) is a martensitic stainless grade that can be precipitation hardened through aging/heat treatment. 17-4 stainless steel, otherwise known as SAE Type 630 is frequently used with operations demanding high tensile strength and a middling level

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.

What makes 17-4 PH stainless steel so good?

Hardened High-Strength 17-4 PH Stainless Steel This material is hardened for improved strength and wear resistance. Easy-to-Machine High-Strength 17-4 PH Stainless Steel Also known as Project 70+, this material machines faster with less wear on cutting tools than standard 17-4 PH stainless steel.

What is the chemical makeup of stainless steel?

SAE Type 630 stainless steel (more commonly known as 17-4 PH, or simply 17-4; also known as UNS 17400) is a grade of martensitic precipitation hardened stainless steel. It contains approximately 15–17.5% chromium and 3–5% nickel, as well as 3–5% copper. The name comes from the chemical makeup which is approximately 17% chromium and 4% nickel.
