Solid Wire Electrode BA-WIRE 420 for Submerged Arc Welding
Classification:
SFA 5.9: ER420
Main Application
Wire electrode for submerged arc welding often used for surfacing applications which need superior resistance to abrasion. It requires preheat and inter-pass temperatures of not less than 225ºC, followed by slow cooling. Post weld heat treatment is used to temper the weld deposit.
BA-WIRE 420 is similar to BA-WIRE 410, but with higher chromium and carbon content which increases the wear resistance.

Base Materials
AISI 420, X12Cr13: hardfacing results in higher hardness than with ER410.
Suitable fluxes: BF 38, WP 380
Flux type suitability is strongly dependent on its application. In combination with the wire electrode the most suitable flux should match the requirements of the plate material as closely as possible under the existing welding conditions. Further information can be obtained from the technical flux data sheets.
