Protect Your Electrode From Humidty

AS B - 248 H4R and AS B - 255 H4R

The humidity captured in the flux of electrode turn in to water vapor in the welding bead. Water vapor shrink in the weld bead and porosities occur. These porosities decrease the mechanical properties of the weld metal and the beads becomes unstable.

Due to these negative effects of the humidity, electrodes must be protected in the best way. Askaynak is proud to advise the Vacuum Packages which do not get humid if the package is not open and which has 12 hour critical humidity level guarantee after the package is open.

AS B-248 which is suitable for steel constructions and machines operating under dynamic forces. Ship building, boiler and pressure vessel manufacturing and pipe connections are among its application areas. Also AS B-255 which is especially suitable for fine grained structural steels having high yield strength values. Welding of ship's plate of A-, D- and E- quality, boiler and pressure vessel manufacturing and pipe connections are among its application areas. This two electrode is especially advised in vacuum package by ASKAYNAK with the name of AS B 248 H4R and AS B 255 H4R.
