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

For microscale fine partical & low-grade abrasion working conditions

Anti-wear & anti-corrosive iron

A49

≥600

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 enviroment

Anti-wear & anti-corrosive iron

A33

35

Anti-erosion performance≈A03 corrosion resistance

To transport oxidability slurry of PH valve≥1, such as phosphogypsum, HN03, H2SO4, H3PO4, etc.

A22

1200

45

Excellent erosion resistance, higher hardness

For dredging pump casing

Anti-wear cast steel

A23

700

HB 500-600

Higher hardness and anti-erode

To transport higher anti-wear & anti-corrosive working condition, such as parts of dredging pump, clean water pump, sewage pump, certain parts of slurry pump

Anti-wear cast steel

A25

HB 300-350

Low hardness, higher abrasion resistance, good weldable performance

For light ecrode and wear condition such as transporting aqueous medium of small gravel
