  • dobre właściwości spawalnicze i technologiczne, niski poziom odprysków, łatwe usuwanie żużla, stabilne spalanie łuku i doskonała jakość spoiny
  • przy spawaniu stali różnoimiennych zapewniana jest wysoka odporność na pękanie oraz wysoka odporność na korozję międzykrystaliczną podczas pracy w temperaturze do 300°C . Podobnie jak podczas spawania żaroodpornych stali nierdzewnych, zapewniana jest wysoka odporność na tworzenie się kamienia kotłowego w zakresie temperatur roboczych do 900°C .
M-309L brand electrodes intended for welding various types of steel (austenitic and carbon), austenitic stainless steels such as AISI 304, AISI 304L, etc., where the temperature is not higher than 300 °C, for welding heat-resistant stainless steels AISI 309, AISI 309S and with a similar chemical composition
