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.

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.

R24 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.
