Which kind of welding wire is needed for the welding of No. 20 steel and 316L?
A302, A312, A062, A042, A102, A402, etc. can be used (manual arc welding)Suggest A042 or A402.A402 high temperature 1150 degreesGFS-309MOL (GB/T17853, E309MOT1-1) for carbon dioxideGTS-309MOL for argon arc welding
316, mainly corrosion resistant stainless steel, so the weld must meet the performance of 316 materials, it is recommended to use ER 316 L welding wire.
You belong to the dissimilar steel welding I checked according to the petrochemical dissimilar steel welding procedures SHT 3526-2004 provisions (only check to 20# steel and 304L 321 welding, and no 316L, and 304 with A302) electrode (E309-16) or A307 (E309-15).Or A312 (E309Mo-16) with or can refer to 20# and 304 of the wire used. It is slightly affected corrosion resistance point of view, but the problem is not largeH1Cr24Ni13 for welding wire
