Mark Св-04Х19Н9
Mark Св-04Х19Н9, a global analogue – ER-308 LSi.
The wire is made in accordance with GOST 2246-70 diameter 0,8-6,0 mm.
Application
Chrome-nickel corrosion-resistant wire is used for semi-automatic welding stainless steels: 03Х18Н11, 03Х17Н14М2, 08Х18Н10Т, 08Х18Н10 (ER-304), 06Х18Н11, 12Х18Н10Т, 12Х18Н9Т. When welding using inert gases and DC current. With the help of welding wire Св-04Х19Н9 welded parts boilers, piping, tanks, which are used in the petroleum, chemical, food industry and machine building.

Mechanical properties of the weld:
Toughness – KCV – 110 J / cm2;
Tensile strength – 620 MPa;
Tensile strength – 370 MPa;
Elongation – 36%.
The deposited weld metal has high corrosion resistance, and the content of carbon in it, reduces the risk of intergranular corrosion.
