Secundum necessitates, supplementum unum vel plura frumenti subtiliora elementa addere potest. Maxima vis in mensa erit. Composita, Nb + V + Ti non plus quam 0,22% est.b. Gradibus enim Q345, Q390, Q420 et Q46O, Mo + Cr non est maior quam 0,30%c. Cum cuiusque gradus Cr et Ni elementa residua adhibentur, contentum Cr et Ni maius esse non debet quam 0,30%; cum opus est addere, contenta cum requisitis in mensa, vel a venditore et ab emptore consulto determinentur.d. Si supplementum curare potest ut contentum nitrogenium requisitis in mensa occurrat, analysis contentum NITROGENIUM fieri non potest. Si Al, Nb, V, Ti et alia elementa mixturae cum fixatione nitrogenis ferro accedunt, contentum NITROGENIUM non circumscribitur. Contentum fixationis NITROGENIUM in qualitate certificatorium definiri debet.e. Quando plenum aluminium utens, totum aluminium content Alt ≥ 0020%. |
