Material Selection for Sulfuric acid
Material Selection for Sulfuric acid
(OP)
Hi there,
a pump vendor proposing cast iron pump for sulfuric acid. (%98 at 40 deg. C ( 104 F)
gjl-200 = grey cast iron
I could not find any solid literature defending this. Only high-silicon cast irons looks
suitable.
Could I have your input?

However each application has different characteristics.
I searched a lot for cold %98 acid but could not find
solid proof - different sources contradict with each other.
Thats why open the thread.

It is about the most definitive source.
Gray CI is not a very good option. It is susceptible to cracking (oxidation of C flakes).
A ductile iron is a bit better. But they both suffer from velocity related effects.
In a pump you are better off with a high Si CI (14.5% F47003).

@EdStainless : I dont have this book and I guess it is not sold anymore. I could not also find it on web.
@georgeverghese : IT will be a new line so we have only these data.
Overall, I believe standart iron would be risky considering in such plants it is not easy
to control process and characterisics may change.
