What is the hardness of 17-4 H1150?
28
On the Rockwell C scale, 17-4 H1150 Stainless Steel has a hardness of 28.
What type of stainless 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 difference between 17-4 and 17 4ph?
17-4 PH provides toughness in both base metals and welds. It is well suited to applications that require ease of fabrication and the addition of strength/hardness for improved reliability. Type 17-7 PH stainless steel is a Chromium-Nickel-Aluminum, semi-austenitic stainless steel.
What type of steel 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.
What is 17-4 PH heat treated?
17-4 PH stainless steel is a martensitic stainless steel containing approximately 3 wt pct Cu and is strengthened by precipitation of copper in the martensite matrix. After a solution heat-treatment, this alloy is generally precipitation hardened by tempering at about 580°C.
Does 17-4 PH work harden?
Type 17-4 PH stainless steel is the most common type of martensitic PH stainless steel. At low temperatures of 250 degrees Centigrade, the martensitic alloy transforms to martensite. The stainless steel alloy can harden further by aging at temperatures ranging between 480-620 degrees Centigrade.
How do you heat treat 17-4 to H900?
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.
What does 17-4 PH stand for?
630 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. SUS630 is the same as 17-4PH, and they are both refer to the same grade.
What makes 17-4 PH steel so strong?
17-4 PH Steel contains 4% copper and may be hardened by a single low temperature precipitation hardening heat treatment, producing excellent mechanical properties at a high strength level. 17-4 PH provides this high strength in combination with good mechanical properties at temperatures of up to 600°F (316°C).
What are the mechanical properties of alloy 17-4 PH?
Alloy 17-4PH | Material Datasheet 17-4 PH Steel contains 4% copper and may be hardened by a single low temperature precipitation hardening heat treatment, producing excellent mechanical properties at a high strength level. 17-4 PH provides this high strength in combination with good mechanical properties at temperatures of up to 600°F (316°C).
What are the uses of 17-4PH stainless steel?
Flat Diameter. Applications. Commonly used in industries such as offshore, marine, food, paper mills, oil field and aerospace. 17-4PH is used for components such as fasteners, couplings, screws, bushings, studs, fittings, valve stems, roller, wear rings.
