Dear Zakaria,

the E 7018 not substitute E 7018 A1

E 7018 is electrode for non alloy steel ,and E 7018-A1 is for 16Mo3 materials

Hi All,

  In our boiler project we have to weld socket tube A210 Gr A1,  38 mm diameter , 4 mm thick  to collector P11 material thick , according client WPS we have to weld by E7015-A1.

What's the difference between EXXXX and EXXXX-A1
May E7018 substitue E7015-A1 ?

Kind regards
