Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If not stainless steel, such as carbon steel
Non-stainless flanges have distinct headings based on iron/steel type.
If part of valve or regulator assembly
Flanges integral to valves classify as valve parts, not standalone fittings.
If featuring threaded elements
Any machining like threading excludes it from rough forged category.
