In my experience there is no difference between the pickle characteristics of 304 and 304L.
I need some more info. Is the annealing of your 304 L carried out in an lectric or gas furnace? Is the surface oxidised when it exits the annealing furnace? If that is the case, you removed the passive...
ok, when modelling this pickling process I need reaction kinetic data. My thermodynamics is very rusty, how would I estimate the activation energy of a specific reaction to use in an Arrhenius equation? Is my thought direction correct? What else can I do to model the reaction? is there any info...
Do you have any idea what the reason is for the mixed acid? In my opinion, the Nitric is a strong oxidizing acid and actually attacks the metal oxides. These metal oxides are now in solution. In order to maintain the forward reaction rate, the metal oxides are removed by complexing with the...
I want to model or at least closely approximate the dominant reactions envolved in the mixed acid pickig process (Nitric/HF). In the litreature I found a list of about 25 reactions including al the flouride/metal complexing reactions. Where do I get all the rate constants or how can I...
