Product Detailed

When you say the parts don't get a consistent bright finish,do you refer to oxides or reflectivity? Bright annealing doesn't produce the brightnesI am refering to oxides,which are specifically disallowed in the requirements section.The problem with the oxides is that they are like fine gritI need to get out the thermo book but I think the effectness of bright anneal vs vacuum is that the oxide is actually reduced by the atmosphere inSo how do you specify a bright anneal? I already have the word BRIGHT in the spec title,in three other parts of the spec specifically disallow oI would omit the vacuum alternative.You could put in a guidance for -40c max dewpoint also.See rathmfg/Annealing.pdf for a helpfulThanks,I'm coming to the same conclusion that bright annealing vacuum annealing are mutually exclusive.I found the your link just a few minutesAfter studying the chart a bit,it looks like the silicon in the 430F 430FR may be contributing to the oxide problem.The intersection of Cr2O3 check thread 330-122324 in the metallurgy forum on annealing 17-4.Nitric is the usual means for removing light scale.Is this scale all the way tomcguire The thickness problem is that when the plater is using chemical etching to remove the scale before passivation the process is not exact andTo remove the oxides you might want to try the following procedure.Immerse the part in a solution of 10% NaOH(W) + 3% KMnO4(W) at 80 430f annealing process carpenter#176;C to 95 430f annealing process carpenter#176;C for430FR Technical Data Sheet
