Is Black Malleable Iron weldable?
Thereof, is malleable cast iron weldable?
The chemical composition of malleable cast iron is much the same as that of a typical gray iron, but its properties are much different. It is tough; it can resist shock; it has ductility approaching that of mild steel. However, malleable iron castings can usually be braze welded successfully.
Likewise, what is black malleable iron pipe used for? Black pipe fittings, also called black malleable iron fittings, are used to transport gas and water. They connect to black iron and black steel pipe and form a tighter seal than black steel fittings.
Besides, what is black malleable iron?
Malleable iron fittings are lighter fittings in 150# and 300# pressure class. They are made for light industrial and plumbing use up to 300 psi. Malleable iron fittings, also called black iron fittings, are available up to 6 inch nominal pipe size, though they are more common to 4 inches.
What is black iron pipe made of?
Just like PVC, black malleable iron uses a system of pipe and fittings that fit together with compounds instead of welding. Despite its name, black iron pipe is actually made of a low-grade "mild steel" compound. This gives it much better corrosion resistance than traditional cast iron piping.
