(OP)
Question relates to preparation of 316L seamless pipe and fittings for ship hydraulic lines. Apart from obvious need to clean up pipe sections after cutting lengths, bending, etc before tack welding fittings in place, are there any problems with contamination of weld areas etc if cut-off's were done with disks containing ferrous (carbon steel) materials, manual removal of burrs' etc with carbon steel file.
Major concern is future corrosion in hydraulic lines if they are contaminated with non-stainless metal traces.

If your are talking about cutoff and grinding disks being used on both materials we discourage this practise and do everything to prevent their dual use. I know it has happened on more than one occasion and we have gotten by with it due to the simple reason that if either type disk is working properly it is constantly being worn away. Any contaminated area would show up only briefly.
An ideal situation would be where you have equipment for use on each individual material you are working on at the time.
Our welding of L grade SS is in a very, very corrosive area and any contamination would show up very quickly.
