SV-07Х19Н10Б - 1.4550 - er347 stainless steel welding wire
Welding wire SV-07Х19Н10Б (SV-07Х19Н10Б-e)
The welding wire produced in accordance with GOST 2246−70, RD 03−613−03 and specifications 1220−005−84 823 540−2010. Used for welding of products from chromium-Nickel corrosion-resistant steel 08KH18N10T, 08KH18N12B, 08KH18N12T and similar similar working in hostile environments where no weld metal stringent requirements for resistance to intergranular corrosion. Also, this wire is used for welding of critical components of structures made of austenitic steels: Х16Н13Б, Х20Н12Т-L, 12Х18Н12Т, 12X18H9T, and the like, operating at high pressure and at a temperature of 570−650°C. the Welding wire grade SV-07Х19Н10Б can be used for hardfacing of parts and production of various brands of electrodes (DH-15, CL-11, OzL-7, TSN-12M).
