Applications in Alloy Construction

20Cr hot-rolled alloy steel is widely used in key structural parts of alloy construction, leveraging its "wear resistance + toughness + processability" advantages:

1. Wear-Resistant Structural Components

Sliding Interfaces: Used in hinges, bearing seats, and guide rails of large steel structures (e.g., bridge expansion joints, crane rails). After carburizing, the surface resists wear from long-term friction, while the tough core withstands impact from vibration.

Heavy-Duty Fasteners: High-strength bolts and nuts for connecting large steel trusses. Hot-rolled 20Cr, after quenching and tempering, provides sufficient clamping force and fatigue resistance, ensuring joint stability under alternating loads.

2. Seismic and Load-Bearing Components

Seismic Supports: In earthquake-prone areas, used as energy-dissipating connectors in building frameworks. Its good plasticity allows controlled deformation during earthquakes, absorbing seismic energy without sudden fracture.

Lightweight Load-Bearing Structures: For temporary construction platforms, scaffolding joints, and formwork supports. Compared to high-carbon steel, 20Cr offers better toughness, reducing the risk of collapse under overload.

3. Special Construction Equipment

Construction Machinery Parts: Manufactures hydraulic cylinder rods, pulley shafts, and gear teeth for tower cranes and concrete pumps. Carburized 20Cr resists wear from repeated movement, extending equipment service life.

Temporary Bridge Components: Used in modular bridge decks and connecting pins. Its hot-rolled state allows easy welding and assembly, while post-treatment enhances durability for short-term heavy loads.

 

 

 

 

 

 

Technical Advantages in Construction Applications

Cost-Effective Wear Resistance: Compared to high-alloy wear-resistant steels (e.g., 40CrNiMo), 20Cr achieves surface hardness through carburizing at lower cost, making it ideal for budget-sensitive construction projects.

Balanced Toughness and Strength: Avoids the brittleness of high-carbon steels, suitable for structural parts requiring both load-bearing capacity and impact resistance (e.g., seismic brackets, movable joints).

Easy Processing and Modification: Hot-rolled plates can be cut, bent, and welded on-site, adapting to complex construction layouts. Post-treatment (carburizing, quenching) can be performed locally to enhance performance for key areas.
