hi Tulane,
I am interested what material selection you finally made for this problem and what your experiences are so far...we are concentrating sulphuric acid up to 78%, so we do not have this heat development problem..nevertheless it is an aggressive corrosion environment and the material...
rsmallwood thanks for your comments
Of course corrosion prevention in a rheometer application is quite critical as a slight change in dimensions easily yields fully wrong measurements. I have now found product info on various Hastelloy alloys and believe that they should be able to do the job...
thanks kenvlach !
OK, you're right, let's say 98% H2SO4 is the upper limit. (I read that corrosion rates are often maximum around 70%).
Sorry, I should have been more specific. I am talking about rheometers, so the material has also to be tough, hard and abrasion resistant. PTFE and glass are...
hi guys,
I am in the process of making a selection between devices of various vendors (made of exposed parts of titanium (alloy), SS 420, tungsten carbide ?, hardmetal Co/WC, phosphor bronze). Also one gives Hastelloy as an option.
exposure to: 1 - 100% H2SO4, temperature 20 - 80 degrees C...
