Stainless Steel Electrodes
ES 430 B A5.4: E 430-15 / EN 1600: E 17 B 2 2
Description
ES 430B Electrode with basic coating and low hydrogen level, good weld ability characteristics in all positions, except descending vertical. Mainly used for welding coats in surfaces of valves in contact with gas, water and vapour, allowing resistance to corrosion and wear. In machinery surfaces, it is recommended to keep at least two layers of welding. Similar junctions welded, stainless steel and chromium-bound steel , resistant to high temperatures present good polishing characteristics. Diffusible hydrogen <5ml/100g. Small hardness variation up to 500ºC. Resistant to superficial oxidation up to 900ºC.
