≥56

Anti-erosion performance <A07 with certain corrosion resistance

For higher wear condition 5-12 of PH

A07

Abrasion resistant white iron

mTBCr15Mo

≥59

Best anti-erosion performance, corrosion resistance <A04, A05

For higher wear condition

A01

Abrasion resistant white iron

KmTBCr8

≥55

Anti-erision performance≈90% of A05

For mud pump

A11

Abrasion resistant white iron

KmTBCrMnMo

38-42

Low-grade anti-erosion performance, low hardness, drilling tapping

For microscale fine partical & low-grade abrasion working conditions

A49

Anti-wear & anti-corrosive iron

43-49

Abtu-erosion performance, corrosion stability, in low ph environment, abrasion resistance≈A03

For low-grade PH corrosive environment, expecially suitable fro FGD(PH≥4), Usually used for low acid environment

A33

Anti-wear & anti-corrosive iron

35

Anti-erosion performance≈A03 corrosion resistance

To transport oxidability slurry of PH valve≥1, such as phosphogypsum, HNO3, H2SO4

A22

45

Excellent erosion resistance, higher hardness

For dredging pump casing

A23

Anti-wear cast steel

HB 500-600
