MA Series Hammers

MA Series Hammers

The MA series hammers by CH Casting are a premium line of high manganese steel hammers, meticulously manufactured to deliver outstanding performance in demanding industrial applications. These hammers are specifically designed to provide exceptional hardness, toughness, and wear resistance, making them the ideal choice for heavy-duty crushing and pulverizing tasks.

The MA series hammers are crafted from high-grade manganese steel alloys, carefully selected for their superior mechanical properties. Through advanced manufacturing techniques and precise heat treatment processes, CH Casting ensures that these hammers achieve optimal hardness levels, ranging from 200 to 600 Brinell hardness (HB). This hardness, combined with their toughness, enables the MA series hammers to withstand high-impact forces and resist deformation, ensuring reliable and long-lasting performance.

Moreover, the MA series hammers undergo a specialized work hardening process. This unique feature allows the hammers to self-harden during use, enhancing their wear resistance and prolonging their service life even in the harshest operating conditions.

Designed with precision engineering, the MA series hammers are tailored to deliver exceptional strength and durability. They exhibit excellent resistance to abrasion and can effectively crush and pulverize a wide range of materials, including rocks, ores, minerals, and construction debris.

MA Series Hammers’ Characteristics

  1. Hardness: MA series hammers are extremely hard, making them suitable for applications that require high-impact resistance. They have a hardness level of approximately 200 to 600 Brinell hardness (HB), depending on the specific grade and heat treatment.
  2. Toughness: MA series hammers exhibit excellent toughness, enabling them to withstand heavy impact and shock loading without fracturing or deforming. This toughness makes them ideal for use in crushers, shredders, and other equipment that encounters high-impact forces.
  3. Wear Resistance: MA series hammers have remarkable wear resistance properties, making them suitable for abrasive and high-wear applications. They can withstand repeated impacts and sliding abrasion without experiencing significant wear, resulting in longer service life and reduced maintenance costs.
  4. Work Hardening: One of the unique characteristics of manganese steel is its ability to work harden. When subjected to impact or pressure, the surface of manganese steel hammers becomes even harder, providing increased wear resistance. This work-hardening phenomenon contributes to the longevity and durability of the hammers.
  5. High Strength: MA series hammers possess high tensile strength, allowing them to withstand heavy loads and resist deformation. Their high strength enables them to deliver powerful blows and effectively break down tough materials.
  6. Non-Magnetic: Manganese steel is typically non-magnetic, which can be advantageous in certain applications where magnetic interference is a concern. It allows the hammers to be used in environments where magnetic fields may be present without causing interference or disruption.
  7. Weldability: MA series hammers can be welded using specific techniques and consumables designed for this material. Proper welding procedures must be followed to ensure a strong and reliable bond, as manganese steel can be more challenging to weld compared to other types of steel.
  8. Applications: MA series hammers find extensive use in industries such as mining, quarrying, crushing, and recycling. They are commonly employed in crushers, impactors, hammers mills, shredders, and other equipment used for crushing or pulverizing various materials, including rocks, minerals, ores, and construction debris.
