Nine Piping Solutions 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 Boltstypically 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.
