Magnetic Flow Meter Electrode Material Decay Resistance Performance
Oct 15, 2018

Electrode material decay resistance performance

Electrode Material

Decay Resistance

316L

Used for industrial   water, water, sewage, weak corrosive medium, it is widely used in petroleum,   chemical, urea, vinylon and other industries.

Stainless steel with Tungsten carbide

Used for the medium of   no corrosion and strong up to wear and tear.

Hartz alloy BHB

It has good corrosion resistance of Below boiling point   for all the concentration of hydrochloric acid, also resistant to corrosion   of sulfuric acid, phosphoric acid, hydrofluoric acid, organic acids and other   non oxidizing acid, alkali, oxidation of salt solution

Hartz alloy CHC

Resist corrosion of Oxidizing acid ,such as nitric acid and mixed acid or a   combination of chromic acid and sulfuric acid medium. also resist corrosion of Oxidizing salt as Fe++ +, Cu++   or contain other oxidants, Such as corrosion of a higher than normal   temperature hypochlorite solution, sea water.

Ti

Resist corrosion of Sea water, all kinds of   chloride and hypochlorite, oxidizing acid (including fuming nitric acid),   organic acid, alkali, not resist corrosion of a pure resistance reducing acid   such as sulfuric acid, hydrochloric acid. But if acid contains antioxidants   (such as nitric acid, Fe++ +, Cu++), the corrosion is greatly reduced.  

Ta

With excellent corrosion   resistance, it is similar with glass, except hydrofluoric acid, fuming   sulfuric acid, alkali, almost resist to corrosion of all the chemical can   medium (including hydrochloric acid, sulfuric acid and aqua regia).

Platinum - iridium alloy

Almost Apply to all   chemicals, but not apply to aqua regia and ammonium salt.
