WEAR RESISTANCE AND CORROSION RESISTANCE MATERIAL SHEET
| category | material code | mechanical properties | special properties | typical application | ||
| δw/δb (Mpa) | Ak (J/cm2) | HRC | ||||
| Abrasion-resistant white cast iron | KmTBCr26 | ≥700 | 6-10 | ≥56 | Its erosion resistance is second to KB06, and it has certain corrosion resistance. |
suitable for bearing a larger impact load abrasive wear, and suitable for medium with 5-12 PH. |
| KmTBCr15Mo | ≥550 | 4-8 | ≥59 | Have the best erosion resistance，but its corrosion resistance is not as good as KB03 and KB04. |
suitable for bearing a larger impact load abrasive wear |
|
| KmTBCr8 | ≥550 | 6-8 | ≥55 | Its erosion resistance is about 0.9 times of KB04. | suitable for mud slurry pump and ash slurry pump. | |
| KmTBMnMo | ≥400 | 3-6 | 38-42 | mild erosion resistance, lower hardness, can be drilled and tapped. | suitable for that contain trace fine particles，mild impact load abrasive wear. | |
| Wear resistance and corrosion resistance cast iron | ≥600 | 43 | has certain erosion resistance and corrosion resistance for low PH ambience, its corrosion resistance is similar toKB02. |
suitable for low PH ambience abrasive conditions，especially for flue gas conditions in power plant., desulphurization unit with PH more than 4. Usually used in low acidic conditions。 |
||
| 35 | has certain erosion resistance,is similar to KB02, has certain corrosion resistance. | special for delivering the oxidative slurry with PH less than 1.e.g., phosphogypsum, nitric acid, sulphuric acid and phosphoric acid in chemical fertilizer plants. | ||||
| Wear resistancecast iron | 1200 | 45 | has good erosion resistance, higher hardness | suitable for dredge boat pump. | ||
| 700 | HB 500-600 | higher hardness, great erosion resistance. | suitable for wear resistance , corrosion resistance and higher erosive resistance conditions, e.g., suitable for manufacturing parts of dredging pump, clean water pump , dirty water pump and slurry pump. | |||
| HB 300-350 | lower hardness, better erosion resistance, good weldability. | suitable for mild erosive resistance ,wear resistance , conditions, e.g., delivering aqueous medium with small sand. | ||||
| Natural rubber | R26 |
hardness（Hardness JIS A43±3） 2) tensile strength（Mpa）≥19 3）300%stretchingstrength（Mpa）≥1.9 4）elongation（%）≥500 |
As its hardness and elasticity is better than metallicity, wear resistance and corrosion resistance, better erosion resistance than others. The weaknesses is when using can't scratch. |
Great wear resistance and corrosion resistance, usually used for desulfurization pump, tailing in mining industry, slurry with small particles and no edges. It suitable for manufacturing volute liner. |

hardness（Hardness JIS A50±5） 2) tensile strength（Mpa）≥22 3）300%stretchingstrength（Mpa）≥3 4）elongation（%） ＞500 |
As its hardness and elasticity is better than metallicity, wear resistance and corrosion resistance, better erosion resistance than others. The weaknesses is when using can't scratch. |
Great wear resistance and corrosion resistance, usually used for desulfurization pump, tailing in mining industry, slurry with small particles and no edges. It suitable for manufacturing impeller. |
