Predicting delta ferrite content in stainless steel castings. If your spec calls for a certain amount of ferrite content it should also specify either per schaeffler or by delong or by wrc because they all use different formula s. Provides a step by step display and a print out option showing the finished stringer with cut dimensions and a materials list. If you have issues with the calculator, email strgcalc at microsoft dot com office exchange server role requirements calculator v9. Calculate the reactions at the supports of a beam, automatically plot the bending moment, shear force and axial force diagrams toggle navigation beam guru. Constitution diagrams are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. All values are, of course, purely theoretical and may vary considerably under practical conditions. In effect, the delong diagram traded improved prediction accuracy for. Delta ferrite formation in austenitic stainless steel castings. Use this beam span calculator to determine the reactions at the supports, draw the shear and moment diagram for the beam and calculate the deflection of a steel or wood beam.
Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steel. The schaeffler and delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds.
