Products Description
SS 17-4PH is a stainless steel grade that belongs to the martensitic family and is hardened through precipitation. It consists of alloying elements such as nickel, copper, and chromium. This alloy is commonly used in the aerospace industry for applications such as fasteners and structural components.
The specific grade designation for SS 17-4PH is UNS S17400. The microstructure of this alloy is obtained through a remelting process, which results in a refined structure. This refined structure enhances the toughness of the alloy, making it more resistant to impact and mechanical stresses.
