|
Polytetrafluoroethylene (F4) |
It is a kind of plastic with very stable chemical properties. It can withstand boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia, as well as concentrated alkali and various organic solvents. Not resistant to corrosion by chlorine trifluoride, high-temperature chlorine trifluoride, high-flow liquid fluorine, liquid oxygen, and auto-oxidation. |
70℃ |
100℃ 250℃ |
1. Strongly corrosive media such as concentrated acid and alkali. 2. Sanitary media. |
|
Polyperfluoroethylene-propylene (F46) |
Same as F4, but its wear resistance and negative pressure resistance are higher than F4. |
Same as above |
||
|
Polyfluoroethylene (Fs) |
The upper limit of applicable temperature is lower than that of polytetrafluoroethylene, but the cost is also lower. |
80℃ |

|
Polychloroprene |
1. It has excellent elasticity, high tearing force and good wear resistance. 2. Resistant to the corrosion of general low-concentration acid, alkali and salt media, but not resistant to the corrosion of oxidizing media. |
80℃ 120℃ |
Water, sewage, weakly abrasive mud or slurry. |

Corrosion resistance and wear resistance |
|
Stainless steel 0Crl8Nil2M02Ti |
It is used for weakly corrosive media such as industrial water, domestic water, and sewage. It is suitable for industrial sectors such as petroleum, chemicals, and steel, as well as municipal and environmental protection fields. |
|
Hastelloy B |
It has good corrosion resistance to hydrochloric acid of all concentrations below the boiling point, and is also resistant to corrosion by sulfuric acid, phosphoric acid, hydrofluoric acid, organic acids and other non-chlorinating acids and alkalis, and non-oxidizing salt liquids. |
|
Hastelloy C |
It is resistant to corrosion by non-oxidizing acids, such as nitric acid, mixed acid, or mixed media of chromic acid and sulfuric acid, and is also resistant to corrosion by oxidizing salts such as Fc+, Cu+ or other oxidizing agents, such as hypochlorite above normal temperature. Corrosion from solutions and seawater |
|
Titanium |
It can withstand corrosion from seawater, various chlorides and hypochlorites, oxidizing acids (including oleum), organic acids and alkali. It is not resistant to corrosion by relatively pure reducing acids (such as sulfuric acid, hydrochloric acid), but if the acid contains oxidants (such as nitric acid, Fc+, Cu+), the corrosion is greatly reduced. |
|
Tantalum |
It has excellent corrosion resistance and is very similar to glass. In addition to hydrofluoric acid, fuming sulfuric acid, and alkali, it is almost resistant to corrosion by chemical media (including boiling hydrochloric acid, nitric acid, and sulfuric acid below 50°C). Resistant to alkali; resistant to corrosion. |
|
Platinum/titanium alloy |
It is resistant to almost all chemical media, but is not suitable for aqua regia and ammonium salts. |
|
Stainless steel coated tungsten carbide |
For non-corrosive, highly abrasive media. |
| Note: Since there are many types of media and their corrosiveness is affected by complex factors such as temperature, concentration, flow rate, etc., this table is for reference only. Users should make their own choices based on the actual situation. If necessary, they should conduct corrosion resistance tests on the selected materials, such as coupon tests. | |
