Material | Code | Performance of Corrosion Resistance |
316L | V | Used in industrial water, domestic water, sewage, neutral solution,
and weak acids (carbonic acid, acetic acid, etc). |
Hastelloy Alloy C | Hc | Applicable to oxidation resistance acids, such as nitric acid,
mixed acid, and chromic acid mixed with sulfuric acid. Good corrosion resistance to seawater, alkali solution, and chloride solution. Inapplicable to hydrochloric acid and Hydrofluoric acid. |
Hastelloy Alloy C | Hb | Good corrosion resistance to non-oxidative acid, alkali, salt. Inapplicable to nitric acid. |
Ti | Ti | Good corrosion resistance to sea water,chloride,hypochlorite and
various hydroxides. Inapplicable to reducing acids (hydrochloric acid, sulfuric acid, hydrofluoric acid, etc). |
Ta | Ta | Mostly resistant to the corrosion of all chemical media; generally
used for hydrochloric acid and sulfuric acid. Inapplicable to hydrofluoric acid, alkali, and fuming sulfuric acid. |
Tungsten Carbide | W | Good wear resistance; used for the wearing media, such as mud and
paper pulp. Poor corrosion resistance. |
Platinum-iridium Alloy | Pt | Except for aqua acid and ammonium salt, it is mostly resistant to
the corrosion of all of the acidic, alkaline, and salt solutions |
Material | Performance of Corrosion Resistance | Working Temperature | Applicable Areas | Diameter (mm) |
PTFE | Mostly resistant to the corrosion of all chemical media. | -40~150℃ | All media, except the fluid in negative-pressure pipe and fluids
with good wear resistance | DN15~1200 |
