Effect Of Nitrogen, Manganese, Nitrogen-Chromium On Welded Pipe Fittings Nitrogen acts as a hardener in butt welded pipe fittings. The mechanical properties (yield strength) of butt welded pipe steels with higher manganese, nitrogen and chromium contents are also relatively higher, sometimes than the hardness of 304 chrome-nickel steel. The strength is 30% higher. However, these…
