17-4PH per AMS 5643
17-4PH, as per the AMS 5643 specification, is a martensitic precipitation-hardening stainless steel specification that includes bars, wire, forgings, mechanical tubing, and rings in the solution heat-treated condition. This material has an exceptional combination of high strength, toughness, and resistance to corrosion, making it one of the most versatile stainless steels available.
Product Forms & Size Range of 17-4 PH
Round Bar diameters range from 0.125″ to 14.00″ diameter.
Flat Bar comes in a variety of thicknesses and widths. For more information please request a quote.
Plate Thickness ranges from 0.1875″ to 6.50″ Thick.
Sheet Thicknesses range from 0.002″ to .150″ Thick.
Mechanical Properties and Heat Treatment of AMS 5643
The process by which this is achieved has been outlined by the specifications for AMS 5643. This involves a single heat treatment cycle between 900°F and 1150°F, or 482°C and 621°C. This heat treatment cycle combines solution heat treatment with precipitation hardening. It increases tensile strength and hardness while maintaining corrosion resistance that is on a par with that of Type 304 stainless steel.
Typical Applications of AMS 5643
17-4PH stainless steel per AMS 5643 is ideal for:
- Aerospace fasteners and shafts
- Pump and valve components
- Marine and chemical processing parts
- Oil and gas drilling tools
- Nuclear and power generation hardware
