A182 VS A403
Thread Content
Both ASTM A182 and ASTM A403 apply to stainless steel pipe fittings; what are the differences in their usage? In projects, I’ve seen that socket weld and threaded fittings generally use A182, while welded fittings use A403. What is the basis for this distinction? I would appreciate some guidance from experts, thank you!
The information is very useful; thanks to the original poster for sharing it.
