Welding wire grade Sv-07Kh25N13 (or Saint-07Kh25N13-e) is used for welding of the most important equipment of the rolling heat-resistant steels and castings: 20H23N18, 20H23N13 and similar, which are operated at temperatures up to 1000 ° C in oxidizing environments. It is possible to weld steel 25H25N20S2, 15H25T chromium steel and similar, as well as welding of low alloy and carbon steels with high alloyed austenitic steels. Welding equipment, consisting of a double layer of steel with a layer of doped steels and 12X18H10T 12X18H9T for surfacing intermediate layer and anti-corrosion coating of steel pearlitic on the details. Welding wire Sv-07Kh25N13 produced in accordance with GOST 2246−70, RD 03−613−03 and specifications 1220−005−84 823 540−2010. From it produce electrodes RLA-19, O3L-6, CL-9, 99-LEZ, ZIO-8 OZSH-6 EA-48M / 22, 8 OZSH-designed welding (welding).
