Low Alloy Steel Wire

MAXFIL- 41B3

AWS: SFA 5.29 E90T5-B3C

EN ISO CODE: 17632-B T57ZT5-0CP-G

Maxfil-41B3 is a low alloy steel flux cored wire designed to deposit approximately 2.25%Cr-1.0%Mo weld metal for high temperature creep resistance applications. The wire gives optimum performance under CO2 shielding with radiographic quality weld deposits. The wire produces thin & friable slag covering with shiny bead appearance.

Maxfil-41B3 is designed for single and multi-pass welding of similar composition steels and equivalent grade steels like; Gr. F22 of SA-182 & and SA-336, Gr. T4/T22 of SA-199, Gr. T22 of SA-213, Gr. WC9 of SA-217, Gr. P22 of SA-335, Gr. FP22 of SA-369, Gr. 22/22L of SA-387, Gr. CP22 of SA-426, Gr. 22 of SA-541, Class 1 of A, B types of SA-542, etc.
