Re: [MW:6084] Welding of ASTM A 335Gr.P11

you can use E-7018B2L (not E-7018B2). the "L-Grades" are limited to a maximum of 0.05% carbon. While the lower percent carbon in the weld metal will improve ductility and lower hardness,it will also reduce the high-temperature strength and creep resistance of the weld metal.

Generally it is not a problem with P11, but in case of P22 if the operating temp is > 450 °C, one must not use low carbon grades

Can we use E-7018B2 instead of E-8018B2 for welding of A-335 Gr. P11
material. If yes then what care shall be exercised during welding?
Would the resulting weldment be of adequate strength?


Thanks and Regards
