Sorry, it's 304 alloy.

Assuming the threads involved are formed well (no breakages, material and hole correct size) there should be no issue in using the threads alone. Welding them will only reduce serviceability.D_Hall wrote:Depends on the alloy involved. Some stainless steels are quite weldable. Others are not (or at least, not unless you're a very good welder...but if you were you wouldn't be asking us these questions).kjjohn wrote:I am going to be buying stainless pipes and fittings. For the larger ones I will use screws and o-rings, but on the smaller ones I will be using taps and dies to create threads. Can this stainless threaded part be welded to increase strength?
It is weldable, though assuming you have a good tap and die set the threads will hold easily. (and the correct technique is used).It has excellent forming and welding characteristics.
