Steel welding wire

The feature of steel welding wire according to GOST 2246-70

Steel welding wire is used for welding ( welding deposition) and for making electrodes.

1.Wire size and extreme dimensional inaccuracies:

Steel grade	wire size, mm	limit deviations by diameter, mm
		For welding(welding deposition)	for electrodes
СВ08 - СВ08А	0,8	-0,07	-
СВ08 - СВ08А	1,0-1,5	-0,09	-
СВ08 - СВ08А	1,6-2,0	-0,12	-0,06
СВ08 - СВ08А	2,5-3,0	-0,12	-0,06
СВ08 - СВ08А	4,0-6,0	-0,16	-0,12
СВ08Г2С	4,0-6,0	-0,16	-0,12

2.Steel chemistry by smelting analysis.

Steel grade	mass fraction of elements,%
	С	Мn	Si	Р	S	Сг	Ni	AL
				not less than
СВ08 СВ08А СВ08Г2С	0,1 0,1 0,05-0,11	0,35-0,6 0,35-0,6 1,8-2,1	0,03 0,03 0,7-0,95	0,04 0,03 0,03	0,04 0,03 0,025	0,15 0,12 0,2	0,3 0,25 0,9-1,2	0,01 0,01 0,01

3. Wire is produced in skeins. The skein consists of one section of wire. Each skein of wire is tied up by soft wire in three places in the circle of skein. The weight of wire skein is: diameter 2,0-6,0 mm in the skeins 100-1000 kg.

4. Wire is transported by all modes of transport in covered transport means with protection from mechanical damages and the entry of moisture, with the observance of rules of freighting, which apply to the relevant mode of transport.
