Application of 17-7PH Stainless steel
Classified as a semi-austenitic stainless steel, 17-7 is used extensively in making parts used by the aerospace industry. It is also used in a variety of springs and washers, power boilers, and heat exchangers.
Currently, the 17-7 material is most often used in sheet and strip form when producing springs, clips, and bellows. It is finding new applications in the medical industry due to its high alloy content that provides high, spring-like strength, good ductility, and excellent corrosion, all important attributes for items manufactured for the medical industry.
Vacuum heat treatment technology is allowing the use of 17-7 steel alloy in new medical device design that is based on 17-7’s established set of mechanical properties with the additional benefit of producing bright, non-discolored medical devices. Using this technique does not require removing parts from the furnace for a separate cooling step. This reduces heat treatment costs and provides shiny, cost-effective medical instruments. Though not classified as a standard PH condition, this approach is gaining traction due to the medical industry’s interest.
