Application 

Anti-wear white iron

A05

KmTBCr26

≥700

6-10 

≥56

The ecode resistance is a little bit lower than A07 with certain corrosive resistance.

Used for higher wear condition with PH between 5 and 12.

Anti-wear white iron

A07

KmTBCr15Mo

≥550

4-8

≥ 59

Best erode resistance but lower wear resistance than A04 and A05.

Used for higher wear condition.

Anti-wear white iron

A01

KmTBCr8

≥550

6-8

≥ 55

The ecode resistance is about 0.9 times of A05.

Used for mud pumps.

Anti-wear white iron

A11

KmTBMnMo

≥400

3-6

38-42

Lighter ecode resistance and lower hardness.It can be perforated and tapped.

Used for light wear condition with fine grain.

Anti-wear & anti-corrosive iron

A49

≥600

43

It has certain ecode resistance and corrosive resistance in low PH condition. Its wear resistance is neerly equal to A03.

Used for lower PH condition especially for flue gas. It also can be used for low-sour condition and desulfuration installation with PH not be less than 4. 

Anti-wear & anti-corrosive iron

A33

35 

It has certain ecode resistance that that is similar to A03 and certain corrosive resistance.

It can transport oxygenated slurry with PH not be less than 1,such as phosphor-plaster, nitric acid, vitriol, phosphate etc.

Anti-wear cast steel

A22

1200 

45

Fine anti-ecode & anti-corrosive and high hardness.

Used for dredge pump casting.

Anti-wear cast steel

A23

700 

HB 500-600 

Higher hardness and anti-ecode.

Used for anti-wear & anti-corrosive and high ecode condition such as pasts of dredge pump,clear pump, sevage pump and slurry pump.

Anti-wear cast steel

A25

HB 300-350

Lower hardness, better anti-wear & anti-corrosive and weldable.

Used for light ecode and wear condition such as transport water media contain fine grain.
