How hard can you heat treat 17-4?

Alloy 17-4 can be heat treated to a variety of temperatures to develop a wide range of properties. Its mechanical properties can be optimized with heat treatment where very high yield strength up to 180 ksi can be achieved. Alloy 17-4 should not be used at temperatures above 572°F or at very low temperatures.

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

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.

What type of steel is 17-4?

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 type of steel is 17-4 PH?

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 416 stainless steel?

416 Martensitic Stainless Steel Bar

Chemical Composition
Max %
Hardness 330
High tensile strength and high yield strength but low impact properties when tempered below 400oC.*Note drop in impact properties.Tempering within the range 400oC – 580oC should be avoided.

Can you heat treat 17 4 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.
