Presented indices were used as a basis for determining rational scheme of application of MnS25 for alloying and deoxidation of the ShKh15SG-V steel according to technological option 5--production of an intermediate products partially deoxidized by silicon in the furnace with cutoff of the furnace slag, alloying and deoxidation of MnS25 in process of pouring of the metal into the ladle, deoxidation in the ladle by aluminium on bars and subsequent ladle treatment on the ladlefurnace installations in the vacuumator under oxidefluoride slag (Figure 6).
AG Anderson carried out extensive projects using trial and error methods to determine the FBF for aluminum deoxidized.
From this study, AG Anderson developed filter sizing guidelines for aluminum and titanium deoxidized carbon and low alloy steels (Table 1).

The practice shows that in degassing of not deoxidized by aluminium metal 0.
For each fastener type, one set of samples was given a silicated alkaline clean treatment (Gibson Process 204B), the second set was alkaline cleaned and then deoxidized, and the final set was alkaline cleaned, deoxidized, and conversion coated with either a chromate- or cerium-based (cerate) conversion coating.
FILIFORM MONITORING: The alkaline-cleaned, deoxidized, and cerium-based conversion-coated samples (both Cu and Cu/Ni fastened) were all exposed for a total of 1000 hr.
The deoxidized surface as well as the CeCC and CrCC surfaces all showed isolated filaments developing from the scribe, but were otherwise indistinguishable in the optical images.
In the case of the alkaline-cleaned and deoxidized samples, after initiation, many of the filaments merged and developed into a common corrosion front emanating from the scribe around the fastener.
The filaments on this sample were also wider than those of the deoxidized or conversion-coated samples.
Oxygen control can be provided by a combination of a cover (even a temporary one), the use of a lightly deoxidized copper such as DLP and the negative pressure applied to the inductor by the vacuum system.
