Stainless steel

Project 7000(TM)15Cr-5Ni stainless steel is said by its manufacturer to offer improved machinability, which in turn reduces part costs, reduces cycle time, and increases productivity. The product is also said to offer the same physical properties of conventional stainless steel alloys, such as toughness, high strength, and corrosion resistance. The material meets current ASTM and AMS specifications, and doesn't require manufacturers to purchase new equipment. Experimental heats were evaluated for mechanical properties, microstructure, and machinability.

"This stainless steel alloy is designed to improve its machining characteristics," says contest judge Francis McMichael of Carnegie Mellon. "Nickel-chromium steels are hard to machine and all improvements are welcomed."
