Steels aloi isel llawlyfr electrod E9018-B92 dwplecs weldio tancer cemegol dur gwrthstaen
Oherwydd ychwanegu swm bach o Nb a V, gall gael ymwrthedd creep ardderchog pan gaiff ei ddefnyddio ar dymheredd uchel 600C.
Croen meddyginiaeth potasiwm hydrogen isel, aloi pontio croen meddygaeth
AC arbennig, gellir ei weldio ym mhob safle.
