Welding wire SV-07CR25NI13 (07CR25NI13-e) used for welding of important equipment based on heat-resistant steels: 20Х23Н13, 20H23N18 and the like, which are operated at temperatures up to 1000 °C in oxidizing environments. This welding wire great weld steel grades 25Х25Н20С2, 15KH25T, as well as low-alloy carbon steel high-alloy austenitic brands. Such wire welded parts from two-layer steels alloyed layer 12KH18N9T, 12KH18N10T or coating or corrosion of pearlitic class steels. Produce overlaying the intermediate layer on the workpiece.


Welding wire SV-07CR25NI13 is made according to RD 03−613−03, GOST 2246−70, technical specifications. 1220−005−84 823 540−2010. Of the welding wire produce electrodes of the type EA-48M/22, OzL-19, lez-99, ZIO-8, О3Л-6, CL-9, OSS-6, OSS-8, intended for welding (welding).
