What type of SS is 17-4?

What type of SS is 17-4?

SAE Type 630 stainless steel
SAE Type 630 stainless steel (more commonly known as 17-4 PH, or simply 17-4; also known as UNS S17400) 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.

Will 17 4ph rust?

The use of type 17-4 PH stainless steel, which has a high resistance to corrosion, has been of great significant value in the paper industry. As you can see, this also reduces costs because the equipment will not succumb to the effects of corrosion and breakdown.

Is 17 7ph stainless steel magnetic?

Type 17-7 PH is a Chromium-Nickel-Aluminum, austenitic stainless steel. It is the most formable of all PH grades and has the highest strength and hardness. It is less magnetic than other PH grades and offers minimal distortion upon heat treatment.

What is s17400 steel?

Allegheny Ludlum’s AL 17-4™ Precipitation Hardening Alloy (S17400), Type 630, is a chromium-nickel-copper precipitation hardening stainless steel used for applica- tions requiring high strength and a moderate level of corrosion resistance. High strength is maintained to ap- proximately 600°F (316°C).

What is 1717-4 stainless steel?

17-4 Stainless is a martensitic chromium-nickel-copper stainless steel in the solution treated (annealed) condition. It can be further hardened to various strength levels by a single precipitation hardening heat treatment that minimizes scaling and distortion.

What is 17-4 stainless steel used for?

Uses for 17-4 stainless steel 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 is the annealing condition for Al 17 4?

The AL 17-4 Precipitation Hardening Alloy is furnished in the annealed condition. This is also called the solu- tion 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 tem- perature.
