Code | Material # | Hardness HRC |
Performance | Application |
A01 | KmTBCr8 | ≥55 | Abrasion-resistant performance is about 10% less than A05 | Mud & slag application |
A03 | KmTBNi4Cr2 | ≥56 | Abrasion-resistant performance is about 20% less than A05 | Neutral water-sand slurry and applications with lower impact load |
A05 | KmTBCr26 | ≥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 | KmTBCr15Mo3 | ≥59 | Best abrasion-resistant performance; corrosion-resistant performance is inferior to A05 | High impact load abrasion condition |
A11 | KmTBCrMnMo3 | 38-42 | Mild corrosion-resistant; lower hardness; drilling and tapping operations are applicable. | Fine particles with light abrasion. |
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. |
