This material is hardened for increased wear resistance over standard 420 stainless steel. Suitable for making molds, 420 stainless steel is a hard, wear-resistant material that can be finely polished to a very smooth surface. It maintains its corrosion resistance in temperatures up to 1150° F.. For technical drawings and 3-D models, click on a part number.
Jan 21, 2006· Friction welding is one of the most economical and highly productive methods in joining similar and dissimilar metals. It is widely used in the automotive and aerospace industrial applications. Ferritic stainless steel (AISI430) is normally difficult to weld by fusion methods, due to the associated problems such as grain growth and retained austenite content. Such problems can be alleviated by ...
Changing the process parameters when manufacturing parts effects how the parts wear. The materials used were Stainless Steel 420 and 90/10 bronze. The process parameters that were changed were the layer thickness and the force. Samples were tested in order to rank the materials based on wear. Samples that had thinner layers wore less
Purpose: The aim of this study was to evaluate the extent to which titanium aneurysm clips could improve the quality of MR imaging compared with stainless steel clips, and to determine whether the clip artifacts could be reduced by controlling certain MR imaging parameters in frequently used pulse sequences. Material and methods: The metal artifacts induced by 3 aneurysm clips were compared in ...
