Cast iron pipe fitting thread connect plumbing names and parts
Pipe fittings, also known as pipe parts, are a kind of accessories that play a role in connection in the pipeline. There are many types of pipe fittings, and threaded malleable cast iron pipe fittings are used more. This type of pipe is widely used in water and gas pipelines.
What’s the difference between ductile iron , gray iron and malleable cast iron ?
1: The characteristic of ductile iron is very tough, graphite is in the form of a ball.
2: The feature of gray iron is very brittle , graphite is in the form of strip .
3: The particularity of malleable cast iron is graphite is a group of flocculent tiles .

So the ductile iron is hardest , malleable cast iron is harder than gray iron .
Why the the toughness of them is different ?
The big reason is time of annealing . If it annealing long time , then the cost also is higher and the quality also is better .
