Properties of KH / Corrosion resistance

KH exhibits superior corrosion resistance since the binder phase is composed of stainless steel or an Ni-based alloy.

Corrosion resistance to sulfuric acid aqueous solutions

Soaked in a 10 wt% aqueous sulfuric acid at 40°C for 10 hours

Corrosion resistance to nitric acid aqueous solutions

Soaked in a 10 wt% aqueous nitric acid at 40°C for 10 hours

Corrosion resistance to phosphoric acid aqueous solutions

Soaked in a 10 wt% aqueous phosphoric acid at 40°C for 10 hours

Corrosion resistance to seawater

Soaked in seawater at 20°C for 30 days
