Constitution diagrams are used to predict ferrite level from the composition by comparing the effects of austenite and ferrite stabilising elements. In the welding of austenitic stainless steels, the. We would like to show you a description here but the site wont allow us. The schaeffler group is a global automotive and industrial supplier. Abstract the microstructures of 50 high mn steels, which were annealed at approximately c and then water quenched, were predicted using the original schaeffler diagram, the modified schaeffler diagram with shifted phase boundaries, and equations for cr. A nickel equivalent is calculated for the austenite stabilising elements and a chromium equivalent ferrite stabilising elements. Accordingly, it is expected that the modified schaeffler diagram is. Our ewm schaeffler program is a powerful tool which indicates the right ewm welding consumable to use for the parent metal and expected dilution that you select or enter.
