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