Excellent mechanical properties of deposited metal and increased corrosion resistance in aggressive environments at temperature from -196 up to 350°С. High resistance to nitric acid action is noted. Negligible content of carbon reduces the probability of formation of intercrystalline corrosion without adding of such stabilizers as niobium and titanium, and high content of silicon provides convenience and simplicity of application in the process of welding.
PURPOSE AND FIELD OF APPLICATION
Corrosion-resistant chrome-nickel welding wire ER308LSi is used for semi-automatic stainless steels welding of Н17N14М2, 03Н18N11, 06Н18N11, 08X18H10T, 03H18N10, AISI 304L, AISI 304, AISI 321, AISI 347 types and other austenite steels of 300 class. It is widely used in food, pharmaceutical, military, wood-working and cellulose industries, machine building, construction of tanks and pipelines, etc.
APPLICATION CONDITIONS
It is recommended to perform welding in gas mixtures (М12Ar+0.5-5%CO2, М13Ar+0.5-3%O2) at direct current of reverse polarity. Precision layers winding provides uniformity and stability in wire feeding to the welding zone.
