Slurry Pump Castings, Slurry Pump Spares

Tobee Slurry Pump Castings
Slurry Pump Castings include Impeller, Shaft, Pump Casing, Liners, Frame Plate, Cover plate, Throat bush, Volute, Elbow, Wear plates etc, and the Main material is Cr27 High chrome white iron castings based on the ASTM A532 Class III Type A. It is available to offer a customer-friendly services. All of the custom wear parts can made to supplied samples or drawings.

Cr27 is a modified High Chromium White Iron developed to provide the highest degree of toughness while retaining excellent abrasion resistance. This alloy is particularly suitable for applications involving abrasion and sudden impact such as large diameter dredge pump impellers.

The inoculated microstructure yields a very tough matrix with sufficient carbide volume to assure long service life. In addition a thermal process toughens the martensitic structure and adds to the impact strength of this alloy.

ASTM A532 High Chrome Castings

The ASTM A532 specification refers to a group of high chrome white cast irons that have been engineered to offer high abrasion resistance to gouging. These alloys are particularly effective in industries such as the Oil Sands, mining, recycling and hydraulic fracturing.
At Penticton Foundry we work in partnership with you to find solutions to your wear problems.  Based on your requirements and feedback we design and engineer an alloy that fully meets the ASTM A532 Standard.  In doing so we maximize your run-time and reduce the number of stoppages and change outs.  Our abrasion resistant cast irons can be supplied in a variety of compositions and hardness.  Depending on your needs, Penticton Foundry can cast to finished size and/or fully machine your component. If you’re wondering why chrome white iron (ASTM A532) is so abrasion resistant, read this.

ASTM A532 Class III Type A*
These alloys are usually called high chrome white irons, and contain between 11% and 30% Cr, as well as other elements, to promote the presence of carbides in their microstructure.
By altering chemistry and processing, the hardness levels have a wide range, allowing Penticton Foundry to design exactly what is needed.
ASTM A532, high chrome white iron, is highly abrasion resistant, and so shines in applications involving wear, or a combination of wear and corrosion/oxidation.

Pliant 25
This alloy is softenable to allow for drilling, tapping and broaching. The chemistry, processing and heat treatment of this alloy make it the perfect choice when you need to drill, tap and/or broach. After these machining operations, it can be hardened (typically to >600 BHN) before being put into use. It is especially useful for pump or hydraulic fracturing components like volutes, impellers and liners.

Granite25
Granite 25 is our most common alloy, and is typically supplied at a hardness >650 BHN. It is used across all industries any time there is a need for abrasion resistance. It is used for pumping slurries in the mining, Oil Sands and other industries. It is also used for crushing applications in mining, the Oil Sands, recycling and other industries.

Diamond25
This alloy has the highest percentage of carbides, and therefore, a hardness that usually exceeds 680 BHN. It is typically found in the mining and recycling industries for parts like chute liners and blow bars.

Tough25
This grade of ASTM A532 is alloyed to increase the toughness and through-hardness in thick section castings. It is particularly useful in applications like a gyratory crusher in the mining industry, or any pulverizer that crushes abrasive media.

Other Abrasion Resistant Alloys
The ASTM A532 specification has several other types/grades that have different chemistries and properties. See below for details.

Nihard 1 (Class I Type A)
This alloy has been in production for the longest of any of the abrasion resistant alloys. It contains nickel and chromium and can be very cost effective, depending on the current price of these commodities. Nihard 1 is used in wear-applications, and is especially useful when transporting mixed cement.

15-3 (Class II Type B)
This alloy has a slightly higher toughness, due to the reduction in the amount of carbides in the matrix. It is a good choice in the mining industry, for applications like ball mill liners. It is also used in dredging components, as well as in roller crushers and pulverizers.

0-1 (Class II Type D)
This alloy is as hard as the 25% Cr alloy, but with a little more toughness, and a little less corrosion resistance. The hardness is maintained by the addition of molybdenum. It is a good choice for the mining and crushing industries, where thicker castings are used.

30% Cr
30% chrome white iron is the most corrosion resistant of the ASTM A532 iron alloys. It has found a real niche in flue-gas desulfurization, as well as other oxidizing environments and some reducing environments. It is not as abrasion resistant as the other high chrome white iron alloys.

*Unique Alloy – Pliant25 ASTM A532 Class III Type A
We are proud to offer Pliant25 ASTM A532 Class III Type A which is the best alloy that can be used when drilling, tapping and broaching is required.  After machining it is heat treated to approximately 600 BHN.

Applications
This alloy meets the requirements for many applications such as mining crusher liners, chute liners, ball mill liners (and lifter bars), slurry pumps, frac pumps, dredge pumps, impellers, oil sands applications, concrete rock crushing and recycling-machine parts (blowbars).
