✓ The design of an aneurysm clip and the choice of its component materials require complex considerations of corrosion resistance, biocompatibility, desired performance, and manufacturing practicalities. This study analyzed 10 different types of aneurysm and microvascular clips for chemical composition and metallurgical characteristics. The opening force of each clip was determined with a spring gauge. All components of four multicomponent clips (three aneurysm clips and one microvascular clip) were manufactured from 17-7PH stainless steel, a strong precipitation-hardening grade of good general corrosion resistance. Two multicomponent clips (one aneurysm clip and one microvascular clip) each contained three components manufactured from different alloys. In an implanted clip, an increased rate of corrosion may result from electrolytic reaction between components composed of different alloys. This study demonstrated that 17-7PH stainless steel is a popular alloy for use in vascular clips, but it has several drawbacks. The authors suggest that manufacturers explore the use of PH15-7Mo instead. PH15-7Mo is another precipitation-hardening stainless steel, but contains molybdenum, which renders it potentially more resistant to corrosion than 17-7PH.

Abstract Allvac 13-8 has good fabricability and can be age hardened by a single treatment in the range 510-620 deg C (950-1150 deg F). Cold working prior to aging enhances the aging. This martensitic precipitation-hardening stainless steel has very good resistance to general corrosion and stress-corrosion cracking. It develops very high strength and exhibits good transverse ductility and toughness in heavy sections. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and shear strength as well as creep. It also includes information on high temperature performance and corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: SS-866.

Abstract Crucible 174 SXR is a premium-quality precipitation-hardening stainless steel designed for use as rifle barrels. It is a modification of Crucible’s 17Cr-4Ni that offers substantially improved machinability without sacrificing toughness. Its excellent corrosion resistance approaches that of a 300 series austenitic stainless steel, while its high strength is characteristic of 400 series martensitic stainless steels. At similar hardness levels, Crucible 174 SXR offers greater toughness than either the 410 or 416 stainless steels which are commonly used for rifle barrels. This datasheet provides information on composition, physical properties, hardness, and elasticity as well as fracture toughness. It also includes information on forming and heat treating. Filing Code: SS-1034. Producer or source: Crucible Service Centers.
