Sand casting has various characteristics and advantages and disadvantages when applied to materials such as wearresistant steel, high chromium steel, and high manganese steel. 

Here is an introduction to these materials and their applications:

WearResistant Steel (High Manganese Steel)
Composition: Contains over 10% manganese and 0.8% to 1.5% carbon.
Advantages:
   High strength, high toughness, and high wear resistance.
   Can withstand significant impact and abrasion.
Applications: Suitable for parts in excavation machinery (chains, shovel teeth, and buckets), various crushers (outer covers, linings, and hammers), cement plants (hammers and various types of screen plates), railways (rails and turnouts), etc.
Disadvantages: High processing costs.

High Chromium Cast Iron
Composition: Contains 15% to 28% chromium.
Advantages:
   High hardness, high heat resistance, and corrosion resistance.
Applications: Commonly used in sandblasting machines (blades, distributors, and control cages), pulp cutting heads, cement plants (grinding balls and various types of screen plates), sand pumps and impellers, steel plants (various linings and screen plates, coal grinding balls and disks, impact blocks, and gravity bars), etc.
Disadvantages: Prone to cracking during the machining process, requiring special attention to cooling and processing procedures.

In summary, the selection of appropriate materials depends on the characteristics and application environment of the required components. If high wear resistance and impact resistance are needed, high manganese steel can be chosen; if heat and corrosion resistance are required, high chromium cast iron can be considered.

High Manganese Steel Characteristics
High manganese steel is a highalloy steel with the following main features:

Composition: Manganese content exceeds 10%, and carbon content ranges from 0.8% to 1.5%.
Advantages:
   High Strength: Due to its high manganese content, it has higher strength compared to ordinary steel.
   High Toughness: High manganese steel is highly impactresistant and can withstand significant impact forces.
   High Wear Resistance: Suitable for use in highwear environments, especially those requiring frequent friction and abrasion.
Applications:
   Excavation Machinery: Chains, shovel teeth, and buckets.
   Crushers: Crusher housings, coverings, liners, and hammers.
   Cement Plants: Hammer heads and various types of screen plates.
   Railways: Rails and turnout machinery.
Disadvantages:
   High Processing Cost: The processing of high manganese steel requires more complex techniques and equipment due to its hardness and strength, which increases cost.
   Difficult to Process: Its high strength and hardness make it more challenging to process than ordinary steel.

Applicable Fields
High manganese steel is most commonly used in environments requiring high wear resistance and impact resistance. For example, components in engineering machinery and crushing equipment used for excavation and crushing, parts in cement plants used for abrasion, and turnout machinery in railway tracks.
