E308-16 2.0/2.5/3.2/4.0/5.0 mm Stainless Steel Electrodes
E308/308L-16 is an extra low carbon electrode for the welding of type 304L, 321, and 347 stainless steels. The controlled ferrite in the weld deposit gives excellent notch toughness at cryogenic temperatures. This electrode deposits a maximum of 0.04% carbon in the weld metal to minimize the formation of chromium carbides and consequent susceptibility to intergranular corrosion.
Conform to Standard
GB/T 983 E308-16
AWS A5.4 E308-16
ISO 3581-A-E(19 9) R 3 2
ISO 3581-B-ES 308-16
Purpose:Used for welding the corrosion resistant stainless steel structure, such as 06Cr19Ni10 and 06Cr18Ni11Ti and their working temperature should be below 300℃

Notes:
1.The electrode must be preheated at the temperature of 300°C for 1 hour. Preheat the rod whenever it is used
2.Preferred DC power supply, electric current should not be high.
