17-4 PH stainless steel
what is 17-4 PH stainless steel ?
The 17-4 PH consists of 17% chromium, 4% nickel and 4% copper. This stainless steel is a precipitate-hardened martensitic stainless steel. 17-4 PH stainless steel has excellent strength and corrosion resistance and is commonly used in medical, food service, aerospace and other industries.
17-4 PH stainless steel application
17-4 PH stainless steel is a precipitation-hardening martensitic stainless steel. 17-4 PH stainless steel is used in applications requiring high strength and a moderate level of corrosion resistance. Common applications include nuclear power, aerospace, petrochemical, and food processing. Other applications include valves, pumps, shafts, blades, fasteners, and aircraft components.
17-4 PH stainless steel characteristic
17-4 PH stainless steel is a precipitation-hardened martensitic stainless steel. It is one of the most widely used precipitation-hardened grades, and possesses good corrosion resistance, toughness, high hardness, and strength. It also offers a wide range of mechanical properties at both elevated and cryogenic temperatures. It is magnetic and is not heat treatable.
