| Specification: | GB | F55A4-H08MnMoA |
GB F55A4-H08MnMoA is a Chinese standard for stainless steel welding wire. According to this standard, H08MnMoA is a grade of stainless steel that is commonly used for welding. Its tensile strength is 640 MPa.
GB F55A4-H08MnMoA is a low-carbon, high-manganese and molybdenum stainless steel that is highly weldable and has good corrosion resistance. The wire is suitable for use in a variety of applications, including construction, automotive, and general fabrication.
( 1 ) Collocation high alkaline flux，the impact of the melting gold is superior.
( 2 ) Ray detection is intelligent，welding bead appearance is smooth and beautiful, welding slag stripping is good.
( 3 ) Suitable for the butt welding and fillet welding in X70 pipeline, shipbuilding, steel structure, pressure vessel, bridge .
