    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 to KB02.

    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 resistance cast 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%stretching strength（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%stretching strength（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.
