ASME B16.47 Series A (MSS SP44) refers to a set of American Society of Mechanical Engineers (ASME) standards governing large diameter steel flanges. These flanges are typically used in high-pressure and high-temperature applications, such as in the oil and gas industry, chemical processing, and power generation.

Materials:

1. Carbon Steel (ASTM A105/A105N, A694 F42-F70, A-350 LF1/LF2)
2. Stainless Steel (ASTM A182 F304, F316/316L, F321)
3. Alloy Steel (A182 F5, F9, F11, F22)
4. Duplex Stainless Steel (A182 F51)
5. Nickel Alloys (B564 N06625, N08825)
