Many businesses prefer the fact that Inconel 600 is a very versatile alloy. Therefore the alloy is used in several key industries in various forms including the popular Inconel 600 Pipe. The construction of these pipes could be either welded or they could be seamless. There are benefits to using both. For e.g. the preference of an Inconel 600 Welded Pipe, is in applications where its economics plays a very important role. Though cheaper than the seamless constructed one, these pipes have a longitudinal seam, which could become susceptible to intergranular corrosion – if they are improperly processed. In a scenario, where the buyer requires the highest form of corrosion resistance and the ability to withstand a higher pressure, Inconel 600 Seamless Pipe is the best option.

Hastelloy C-276 is a Ni Mo CR superalloy added with tungsten, which has excellent corrosion resistance in a wide range of harsh environments. The high content of Ni and Mo makes the Ni steel alloy particularly resistant to pitting and crevice corrosion in reducing environment, while CR transfers the performance of anti-oxidation medium.

Although molybdenum is a good element, excessive use of it may reduce the creep ductility of Gr F11 plate flanges. Graphitization and decomposition of iron carbide may occur when the temperature exceeds 500 degrees Celsius. Chromium has been added to SA A182 F11 alloy steel CL.2 forged pipe flanges to prevent creep ductility reduction and graphitization. In addition, the added chromium also provides oxidation resistance.
