Critical fastener applications demand a combination of high strength and high resistance to corrosion. Either criterion alone is easy to meet with conventional materials - high-strength alloy steels for one and stainless steels for the other. However, combining the two requires alloys with as much as 50% nickel, substantial percentages of chromium or cobalt, and for some alloys, little or no iron. In addition to chemical composition, properties of high-strength, corrosion-resistant fasteners depend on specific manufacturing practices. For example, fatigue performance is optimized through controlled forging practices, precision grinding, rolling rather than machining (cutting) the threads, and cold working the fillet radii after heat treating. These carefully controlled and monitored manufacturing techniques along with critical nondestructive and destructive inspection assure the product consistency required for high-performance applications.
