ASTM A182 F12 alloy steel flanges also contain niobium to prevent sensitization and resulting intergranular corrosion.

The plates are annealed in different condition which offers them strength. Since these plates are to be worked at high temperatures and pressure environment therefore the elements included in it matters a lot. What elements are added in the manufacturing add different properties for example, high level of chromium adds excellent corrosion resistance. It also offers excellent oxidation resistance. Resistant to oxygen is important in petrochemical and gas industries and therefore these plates are used.

Inconel600 is suitable for welding with the same material or other metals by any traditional welding process, such as tungsten electrode inert gas welding, plasma arc welding, manual sub-arc welding, metal inert gas shielded welding, molten arc inert gas shielded welding, and pulsed arc welding. Welding is the preferred solution. When using manual arc welding, it is recommended to use a shielding gas mixed with various components (Ar+He+H2+CO2).
Welding of Incoloy 825 must be carried out in the annealed condition and cleaned with a stainless steel wire brush to remove stains, dust and various markings. When welding the root of the weld, extreme care must be taken (Argon 99.99) to obtain the best quality of the root weld so that the weld does not produce oxides after the root has been welded. Color from the weld heat-affected zone should be removed with a stainless steel brush while the weld area is not cool.
