Description

Steel SV-10Х19Н23Г2М5ФАТ used: for the production of welding wire with a diameter of 2.0 to 6.0 mm, used for welding high strength steels of various classes, including austenitic manganese steels.

Note

High-alloy stainless steel. Steel provides high stability of arc burning, spontaneous separability of the slag crust, as in the welding of pearlitic and austenitic manganese steels, low tendency to hot cracking, absence of pores and high strength properties of the weld metal.
