Comparison of cost effective Cr-Ni steel with common high performance powder metal steels

In order to achieve high performance, the powder metal (PM) industry has relied upon alloys containing high amounts of nickel and molybdenum. Recent volatility in the price of metals has spurred the development of leaner alloys. A newly developed chromium – nickel steel has been shown to provide exceptional mechanical properties. In this paper, the properties achievable with the newly developed steel will be compared against common PM material systems. Static and dynamic properties will be compared using both test bars and components.
