High Chrome White Iron (ASTM A532)

• High chrome white iron is composed of Carbides and Martensite (among the hardest phase of iron alloys).
  
  
• This combination makes chrome white iron exceptionally wear-resistant and strong, but gives it virtually no toughness.
  
  
• When solving wear-related problems chrome white iron should be one of the first materials you explore.

Note: We have perfected our process to provide castings that exhibit consistent through-hardnesses for different thicknesses.  We are also able to fully machine our HCWI and supply it to you in the hardened state.

• Any time an abrasive medium has to be transported, high chrome white iron (HCWI) is one of your best options to extend the life of the vessel used for transportation.
  
  
• Pumps, impellers and suction or bearing liners are some of the most common uses for chrome white iron.
  
  
• Chute liners, apron-feed liners, and gyratory crusher liners are very common uses in the mining industry. 
  
  
• Recycling-plant parts like blow bars, anvils and throw shoes are best made in high chrome white iron.
  
  
• Hydro-transport parts like laterals, wyes, reducers and elbows can be made with our chrome white iron.
  
  
• If something you use is wearing out too soon, contact us.

  Ductile Iron
(ASTM A536)

• Ductile Iron has spheres of graphite in it, as opposed to gray iron which has flakes of graphite in it.
  
  
• These spheres give ductile iron its ability to flex, or be forgiving (ductile).
  
  
• The rest of the microstructure can be fully ferritic (low strength) or fully pearlitic (high strength).
  
  
• We commonly pour the 60-40-18, 65-45-12, 80-55-06 and 100-70-03 grades. We will also pour the 120-90-02 grade if you require it.
  
  
• The first number represents the material&#;s ultimate tensile strength (in ksi), the second number represents the material&#;s yield strength (in ksi) and the third number represents the material&#;s elongation (in percentage).
  
  

• Any time you need to design a component with a fabrication or casting think about using ductile iron.
  
  
• You can generally replace a steel fabrication with a ductile iron casting.
  
  
• Ductile iron is much stronger than gray iron, but it also has flexibility (ductility) and will stretch or bend (like steel) before it fails.
  
  
• Ductile iron is very cost effective and is easily cast into very complex shapes:  cable drums, planetary hubs, transmission housings, bearing housings, motor housings, support brackets, pump casings, impellers, stuffing boxes, pedestals, gears, gear housings, sheaves and pulleys are just a few of the parts that can be made in ductile iron.
  
  
• Industries served include oil and gas, OEM, automotive, railroad, truck, agriculture, construction, pump and mining.
  
  

      Austempered Ductile Iron (ASTM A897)

• Austempered ductile iron is made by taking high quality ductile iron and heat treating it so that it is composed of acicular ferrite and ausferrite. 
  
  
• ADI&#;s strengths will be double those of ductile iron&#;s, while still retaining some elongation (ductility).
  
  
• High strength, lightweight castings can be manufactured using ADI and in many instances it will perform better than other materials &#; for a lower cost.
  
  
• Penticton Foundry makes seven different grades of ADI, including Carbidic ADI; which is the most wear-resistant of the ADI grades.

• Austempered Ductile Iron (ADI) has great strength, good wear resistance and a great strength-to-weight ratio. 
  
  
• It can be used anywhere ductile iron is used.
  
  
• It can replace cast steel or even forged steel in some instances. 
  
  
• It can even be made thin enough to replace aluminum components, saving weight as a result. 
  
  
• Industries served include automotive, truck, agriculture and OEM. It is typically used for gearboxes, powertrain components, drivetrain components and structural components.
  
  

       Gray Iron (ASTM A48)

• Gray iron has flake graphite in it &#; results in non-existent ductility and the low strength.
  
  
• It will not bend if stressed beyond its tensile strength and will fracture without warning.
  
  
• Gray iron, however, is still one of the most widely used alloys.  One just has to design within its limits.

• Gray Iron does not possess any ductility, but it is one of the best alloys money can buy for its damping capacity and resistance to thermal shock.
  
  
• It&#;s typically used for engine blocks, counter weights, municipal castings, machine bases, pump casings, housings, water pipes and fittings.
  
  
• Class 20, Class 30 and Class 40 are commonly poured gray irons.

The dredge pump impeller is easy to be worn out, so we search for the special materials to prolong the lifespan of impeller, high chrome white iron is one of them, aims at handling the slurries with strong abrasion or sharp particles.

High chromium irons provide excellent erosion resistance and a reasonable degree of corrosion resistance due to their high alloy content, thus surpassing all other cast irons for use in aggressive services. They are recommended for a pH range of 4 to 11 where erosives are present.

WN series dredging pumps are single-stage single suction cantilever horizontal centrifugal pumps with advantages of light weight, good wear-resistan, super dredging performance, perfectly suited for the dredge on the whole construction, high multiple economy benefits, etc.. It throughout meets requirements of the dredge to dredging pumps.
