High Chrome Slurry Pump Impeller Materials:
|
Code |
Hardness |
Performance |
Application |
|
A05 |
≥56 |
Ranks second only to A07 in abrasion-resistant performance; fair corrosion-resistant performance. |
High impact load abrasion condition; PH rate ranging from 5 to 12 |
|
A07 |
≥59 |
Best abrasion-resistant performance; corrosion-resistant performance is inferior to A05 |
High impact load abrasion condition |
|
A33 |
≥35 |
Abrasion-resistant performance is close to A03; fair corrosion-resistant performance |
Oxide slurry with PH rate no less than 1, like phosphor-gypsum in phosphate fertilizer plant, nitric acid, sulph-oacid and phosphoric acid, etc. |
|
A49 |
≥43 |
Fair abrasion-resistant performance, close to A03; fair corrosion-resistant performance in media with lower PH rate. |
Corrosion conditions with low PH rate, especially for flue gas and FGD devices for media of PH≥4; general suitable for lower acid condition. |
|
A12 |
≥62 |
Higher abrasion-resistant performance than A05; fair corrosion-resistant performance; suitable for media with PH rate is 6-16, where A05 is not suitable. |
High abrasive slurry with fine particles. |
|
A61 |
63-68 |
Optimized abrasion-resistant performance than A12 |
High abrasive slurry with fine particles. |
