Product Description

18CrNiMo7-6, 42CrMo, 42CrNiMo Forged Steel Block Alloy Steel for Hydraulic Breaker

Carbon Steel,Alloy Steel  High-Quality Steel Block for Construction Machines. We provide premium-grade forged steel blocks made from carbon steel and alloy steel, specifically engineered for use in heavy-duty construction machinery components. Each block is precisely forged and heat-treated to ensure high structural integrity, excellent machinability, and superior mechanical performance.

Key Features:

  • Material Options:

    • Carbon Steel: 35#, 45#, C45, etc.

    • Alloy Steel: 42CrMo, 42CrMo4, 20CrNi2Mo,  and other grades upon request.

  • Dimensions: Customizable sizes and weights according to your machining or final part requirements.

  • Heat Treatment: Normalizing, tempering, or annealing to achieve desired hardness and toughness.

  • Surface Condition: Rough forged or rough machined, free of surface cracks and scale, suitable for further machining.

Applications:
These forged steel blocks are widely used as raw materials for key components in construction equipment such as:

  • Excavator arms and base structures

  • Crane supports

  • Hydraulic cylinder blocks

  • Chassis and frame parts

  • Drive housings and gearboxes

Advantages:

  • Excellent strength-to-weight ratio

  • High impact and fatigue resistance

  • Enhanced workability for machining

  • Reliable material traceability and quality control

  • Compliant with international material standards
