Nascent Pipe & Tubes is one of the prominent stockiest and dealer for Stainless Steel 316 / 316L Fasteners (Bolts / Nuts), which is being offered at affordable rates and in customized options for our esteemed clients. The welded corners of Stainless Steel 316 Hex Head Bolts typically rust whereas the bulk of the exposed stainless is untouched. Stainless Steel 316L Hex Head Nuts has lower carbon such that when welded the chromium carbide that forms does not deplete the chromium to the point where the corrosion of the stainless is deleteriously impacted.
There does not seem to be a clear reason for this in Stainless Steel 316 Square Bolts and the differences are probably associated with the lower strength of the low carbon type. The low carbon type in Stainless Steel 316L Square Nuts may be easier to shape and form, which in turn may also affect the levels of residual stress left the steel after is forming and fitting up for welding.

This may result in the ‘standard’ types of Stainless Steel 316 Eye Bolts needing more force to hold them in position once fitted – up for welding, with more of a tendency to spring – back if not properly held in place.

The welding consumables for Stainless Steel 316L Eye Nuts are based on a low carbon composition, to avoid inter – crystalline corrosion risk in the solidified weld nugget or from the diffusion of carbon into the parent (surrounding) metal.
