[16F-T12-12] Chromium Low Alloy Steel Powder for High Performance Applications
キーワード：Low alloy, chromium, material properties
To reduce the cost of PM components, approaches like increasing densities to increase mechanical properties or using lower cost alloying elements to improve the cost versus performance ratio have been used. Nickel, copper, and molybdenum have been the most common alloys used in PM. Nickel and copper are very efficient alloying elements, they offer a good balance between properties and ease of utilization. However, PM is competing for nickel powders with the ever-growing battery market boasting price increases, and copper has been on the list of elements to replace for sustainability issues. Moreover, molybdenum is a very costly alloying element. Ferrochromium is a lower cost alloy and is typically used in the prealloyed state reducing possible segregation and improving part to part stability. This paper will compare performance of a low alloy chromium grade in sinter hardening conditions with common sinter hardening grades.
