201 decorative tube wall thickness of 0.9, I do not know what wire, what wire, the lowest cost? We only ask for water to leak
201, water can be, but after welding, welding seam on both sides of the nickel burning, long time will rust, cracking, so it is best to use 304 wire,
The 201 main components of stainless steel is about 0.15%C, 5.5%Mn, 17%Cr and 5%Ni, can be simply expressed as 1Cr17Mn6Ni5, with high Mn content can be relatively poor weldability (formula CE=C+Mn/6+ by carbon equivalent (Cr+Mo+V) /5+ (Si+Ni+Cu) /15 (%), at the same time can be calculated) of the parent material will be affected by the impact of wayward. Therefore, if the wire is directly removed according to the chemical composition, the welding wire according to the following standards can be used: AWS, A5.9, ER307&, ISO14343-B-SS307. Can also upgrade files using AWS A5.9 ER316 standard welding wire. More guarantee for weld quality.
Oh, of course, 201 of the wire, if it does not leak, on the line, not afraid of rust, then use two wire welding is also OK
