SV-08Х20Н9Г7Т, 1.4370 pipe, wire, circle
Relevance
Welding wire brand SV-08Х20Н9Г7Т made in accordance with, RD 03−613−03, GOST 2246−70 and technical conditi. 1220−005−84823540−2010. This wire is used for manual arc welding of the most critical components of structures made of austenitic steel grades: 08KH18N12B, 12KH18N9T, 08KH18N10T, and similar. Wire is also used for parts of internal devices operated at t° 570−650°, high pressure, and used for welding steels of similar marks in the case when the seam is not present stringent requirements of resistance to intergranular corrosion.
Supply
