Staintec 308L (AWS: A5.4 E308L-16)
Used when welding AISI types 304, 304L, 308 and 308L stainless steel. Staintec 308L is a conventional 18/8 stainless steel.
Staintec 309Mo (AWS: A5.4 E309Mo-16)
Staintec 309Mo is a Mo-bearing stainless steel electrode for root pass welding of 316, 316L, 319 and 319L clad steel. It is also used as a first layer in depositing Mo-bearing stainless steel where a high resistance to concentrated acids at elevated temperatures is needed.
Staintec 310 (AWS: A5.4 E310-16)
Staintec 310 is used in the welding of 310, 310S, 405, 410, 430, 446 as well as welding stainless steel to mild steel or for welding air hardening steels without preheat or post weld heat treatment.
Staintec 312 (AWS: A5.4 E312-16)
Staintec 312 is used in the welding of “difficult-to-weld” steels and dissimilar steels. Also used to weld high strength joints.
Staintec 316 (AWS: A5.4 E316L-16)
Staintec 316 is used in the welding of AISI 316 and 316L. The resultant weld is resistant to concentrated acids and corrosive fumes at elevated temperatures in the presence of reducing agents.
Arc length should be short and a “controlled welding” technique is recommended. Stringer beads are better than weaving beads as they induce lower heat input. For best resistance to corrosion, the overall temperature of the base metal should be kept as low as possible and the assembly should be allowed to cool as rapidly as possible
Chemical Analysis of the Weld Metal
Electrodes are packed in 4kg or 5kg boxes which are then packed into 20kg or 25kg shipper cartons.
Place electrodes in an oven at 200°C for half an hour.
