Introduction of ASTM A532 Class I type B Designation Ni-Cr-LoC

Ni-Cr-LoC is a popular abrasion resistant cast iron in ASTM A532 standard class I type B; it is one type of White Iron.

Manufacture Process for ASTM A532 Class I type B Designation Ni-Cr-LoC

  • Sand Casting
  • Shell Casting
  • Lost Foam Casting

Our Services

  1. Sand Casting

    Casting Quality focus on Metal Parts industry, we provide professional service in Metal Casting field.

    Sand Casting is a popular metal form method, are suitable for all materiel, such as grey iron, ductile iron, malleable iron, carbon steel, stainless steel, aluminum and bronze.

  2. Investment Casting

    Also named as precision lost wax casting, mainly suitalbe for carbon steel and stainless steel parts. We also provide grey iron and ductile iron and aluminum and bronze parts by investment casting. It can achieve the best appearance with good tolerance

  3. Shell Casting

    Shell casting method is a good option to replace investment casting and sand casting. the quality is better than sand casting parts, suitable for bulk production.

  4. Permanent Mold Casting

    For aluminum parts and Brozne parts

  5. CNC Machining

    CNC Milling, CNC turning with 5 xix CNC center, we provide precision machining for all castings based on customers design drawings.

  6. CAD Design

    Mechanical Design service based on customers requirement, our software is Solidworks and AutoCAD.

  7. Tools/Mold Design

    Mould design and production will be served for metal casting ad plastic injection industry. Based on our more than 10 years experience, we supply professional molds for our customers in Europe and North American.

What is White Iron?

When white iron solidifies, virtually all the carbon appears in the form of carbides, White irons are hard and brittle, and they break with a white fracture. These irons are usually alloyed with Chromium and Nickel. The hardness is in the range of 500 to 600 BHN, the specific alloying that is required in a function of section size and application; there must be coordination between designer and foundry. These irons exhibit outstanding wear resistance and are used extensively in the mining industry for ball mill shell liners, balls, impellers, and slurry pumps.
