MAC Stain E100
AWS E318
Descriptions & Applications:
High quality rutile type Niobium stabilised stainless steel electrode for welding 19/12/3 Chrome, Nickel, Molybdenum stainless steels, subject to heat and to resist certain acids and corrosive liquids. Suitable for applications where good resistance to general corrosion and pitting is required. Due to niobium stabilisation the weld deposit has good resistance to intergranular corrosion, and is suitable for applications involving high temperatures up to 600° C. Extensive applications are found in chemical and drug processing plants, food, petroleum, and allied industries.
