High Chrome dredge pump liner in machining process

High chrome is common material for wear parts used on dredge pumps, due to its good wear resistance performance and economic cost.  Here bellow video is one dredge pump liner in machining process. This liner is one  dredge pump reserve engineer product, hardness will up to HRC62.

Dredge pump is used all over the world, and our replace liner already tested by client and get good result. Working life can up to 9months on his dredge ship.

Bellow are some information for high chrome you may like to know

1. Hi Chrome Cr27 is a wear resistant white iron that offers excellent performance under erosive conditions. The alloy can be effectively used in a wide range of slurry types. The high wear resistance of alloy Cr27 is provided by the presence of hard carbides within its micro-structure. Alloy Cr27 is particularly suited to applications where mild corrosion resistance, as well as erosion resistance is required.
2. Cr15Mo3 Marten-sic white iron with moderate erosion resistance.
3. A49 is suitable for low PH corrosion duties, where erosive wear is also a problem. The alloy is particularly suitable for Flue Gas Desulphu-rization(FGD) and other corrosive applications, where the pH is less than 4. The alloy can also be used in other mildly acidic environments. A49 has an erosion resistance similar to that of Ni-Hard 1.
