What type of steel is 17-4 PH?
precipitation hardening martensitic 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. Strength and toughness desired can be manipulated by temperate range in the heat treatment process.
What is the hardness of 17-4 stainless steel?
approximately 44 Rc
Properties. 17-4 can be heat treated to high levels of strength and hardness, and features corrosion resistance and machinability comparable to austenitic 304 stainless. Being martensitic, 17-4 is magnetic. 17-4 is capable of being hardened up to approximately 44 Rc when heat treated to condition H900.
Will 17-4 PH rust?
The high strength of type 17-4 PH stainless steel makes it a great construction material for piping at such depths. Second, Type 17-4 PH alloy is resistant to corrosion both on and offshore.
What kind of metal is 17-4?
4 stainless steel
17-4 stainless steel, also known as SAE Type 630, is a common and exceptionally durable type of steel used in a diverse variety of industries and applications. The numbers “17-4” refer to its composition: ≈17% chromium and ≈4% nickel. It also can include between 3 and 5% copper.
What is 17-4 PH heat treated?
Alloy 17-4PH 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. Mechanical properties can be optimized with heat treatment.
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.
How do you heat treat 17-4 PH stainless steel?
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.
Can you heat treat 17-4 stainless steel?
What is the difference between 17-4 and 316 stainless steel?
316 is typical austenite stainless steel casting grade, while 17-4 PH stainless steel is precipitation hardening material grade, which are all defined in American standards. When you compare Stainless Steel 17-4 ph vs 316 for casting, it is obvious that 17-4 PH has the higher hardening content.
Does 17-4 need to be heat treated?
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.
What does H900 mean?
Typical heat treat designations are H900 or H1075; where H900 indicates aging at 900°F for one hour and H1075 indicates ageing at 1075°F for 4 hours. In all cases, it is important to start with material that is in the solution treated condition or more commonly called Condition A.
What are the useful properties of stainless steel?
Corrosion resistance. The corrosion resistance of stainless steel is mostly a result of the chromium content.
What is 17 4 PH 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. The name comes from the chemical makeup which is approximately 17% chromium and 4% nickel.
What is 17 – 4 steel?
The 17-4 stainless steel grade is an age-hardening martensitic alloy that combines high corrosion resistance and strength. Unlike conventional martensitic steels, it weldable by all standard methods, and achieves hardening with simple low-temperature treatment over a short period of time.
What is 17 – 4 stainless steel?
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 of corrosion resistance. 17-4 PH is the most used grade of martensitic precipitation hardenable alloys. 17-4 stainless steel is regarded as the most broadly
