íshín-383B

CLASSIFICATION

CHARACTERISTICS & APPLICATIONS

íshín-383B has nominal composition (wt. %) of weld metal 28 Cr, 31.5 Ni, 3.7 Mo, 1 Cu. These electrodes are used to weld base metal of a similar composition to itself and to other grades of stainless steel. Type E383 weld metal is recommended for sulfuric and phosphoric acid environments. The elements C, Si, P, and S are specified at low maximum levels to minimize weld metal hot cracking and fissuring (while maintaining the corrosion resistance) frequently encountered in fully austenitic stainless steel weld metals.

These electrodes are usable with dcep (electrode positive) only. While use with alternating current is sometimes accomplished, they are not intended for use with this type of current. Electrode sizes 4.0 mm and smaller may be used in all positions of welding.

Storage and Drying Conditions: Hydrogen can have adverse effects on welds in some steels under certain conditions. One source of this hydrogen is moisture in the electrode coverings. For this reason, the proper storage, treatment, and handling of electrodes are necessary.

Holding Ovens: 125°C–150°C.

Drying Conditions: 250°C–425°C for 1 hour prior to use.
