347 round bar

347 stainless round bar stock is a niobium stabilized chromium-nickel austenitic stainless steel material that has a corrosion resistance that is similar to 304. 

347 stainless bar stock is often used in temperatures that range between 800 to 1500F, where it is stabilized against chromium carbide precipitation which then results in the precipitation of niobium carbides. 

This steel has excellent intergranular corrosion resistance even after being exposed to this temperature range and can resist oxidation up to 1500F with high creep and stress rupture properties. The 347 stainless bar stock has an overall good low-temperature toughness and is non-magnetic when in the annealed condition. 

The chemical composition of this metal goes as follows: Carbon 0.08, Chromium 17.0-19.0, Nickel 9.0-13.0, Manganese 2.00, Silicon 0.75, Phosphorus 0.045, Sulfur 0.030, Niobium 10xC min/ 1.00 max.
