KH alloy is effective for all acids.

Corrosion resistance to hydrochloric acid aqueous solutions

• 10 wt% hydrochloric acid aqueous solution
• 40 degree centigrade-10 hours

Corrosion resistance to sulfuric acid aqueous solutions

• 10 wt% hydrochloric acid aqueous solution
• 40 degree centigrade-10 hours

Corrosion resistance to seawater

KH-H alloy corrosion attenuation is less than 1/4 that of Ni group ultra hard alloys, and demonstrates superb corrosion resistance to seawater.

• Seawater (3 wt%NaCl aqueous solution)
• 20 degree centigrade-1 month
