Description:

S-777MXT×A-2 is single or multi-layer welding of various kinds structure such as 0.5%Mo steels used for pressure vessels and boilers S-777MXT×B-2 is single or multi-layer welding of various kinds structure such as 1.25%Cr-0.5%Mo heat resistant steels used for steam pipes of boilers for electric power plant and marine use, equipment for oil refining industries. An agglomerated Aluminate-rutile flux suitable for welded joints on 0.5%Mo steel, heat resistant steel. Especially insensitive to rust, scale and dirt on the surface to be welded. slag detachability in narrow groove and resistance to porosity are excellent. Suitable for welding of thin and medium plate in high speed welding. When welded, has excellent X-ray characteristics and slag removal.
