Alloy 20 is a nickel based alloy. This alloy is a low carbon containing metal. Furthermore, the alloy has been stabilized by the addition of niobium to the chemistry of the DIN 2.4660 Flat Bar. The inclusion of nickel and chromium in the chemistry of the alloy is what gives the Alloy 20 Round Bar fantastic resistance to corrosion, especially in chemical environments. Hence, any alloy 20 round bar supplier would recommend using these bars in chemical processing industries, that deal with chemicals such as nitric acid, phosphoric acid, chlorides, and sulfuric acid, all of which are highly corrosive in nature.
The mechanical properties exhibited by the ASTM B473 UNS N08020 Rod work well in both ambients as well as in elevated temperature conditions. The higher content of nickel in the alloy is what improves the high temperature behavior of the alloy 20 welding rod. Nickel is an austenite stabilizing agent, which means the microstructure of this superalloy is an austenitic one, which is why the formability is considered to be good.
And therefore the metal could be shaped in any form including the Nickel Alloy 20 hex bar or usual shapes such as round or square. The usual problems associated with welding stainless steels is that they tend to get corroded by means of intergranular corrosion. However, because the alloy 200 square bar has been stabilized with niobium, there is no formation of precipitates, which would usually cause sensitization of grain boundary.
