Materials which exhibit properties like ductility, malleability and machinability, make good flanges. Since there are several types of flanges, ideally a material should have the fore mentioned properties, making it easy for producers to manufacture them using standard ASME B16 47 Series Dimensions. Additionally, properties like corrosion resistance and heat resistance behaviour are some of the most sought after properties. These, in turn, are possible to achieve if the buyer chooses to use Stainless Steel AS, in turn,7 Flange. Stainless steels exhibit corrosion resistance in mediums that contain acidic, neutral and alkali solutions. Some grades like alloy 347, 310 and grade 321 stainless steel ASME B16.47 Series A And Series B Flanges perform well despite exposure to very high or elevated temperatures.

The chemistry of these flanges determines the temperature range they are able to tolerate. Stainless steels like 316 and grade 321 are able to resist corrosion because of the unique chemistry. Often nickel-based stainless steel ASME B16.47 Flange is able to resist pitting in addition to chloride stress corrosion cracking. On the other hand, using a molybdenum containing stainless steel ASME B16.47 Reducing Flange improves resistance to seawater.
