Placas de desgaste resistentes a la abrasión

Abrasion resistant wear plates are high-hardness steel materials specifically designed to resist friction, impacto, and abrasive wear in severe industrial environments. These steels are widely used in mining, producción de cemento, maquinaria de construcción, sistemas de reciclaje, y equipos de manipulación de materiales pesados.

Internationally, abrasion resistant steels are classified by hardness level, alloy system, or regional standards. Different countries and manufacturers use different grade naming systems, but most materials are designed around the same principle: achieving a balance between hardness, tenacidad, y soldabilidad.

1. Serie AR (North American Standard)

The AR series is one of the most widely recognized international abrasion resistant steel systems.

“AR” significa Resistente a la Abrasión.

Aplicaciones típicas

• Mining truck liners
• Revestimientos de trituradora
• Tallas transportadoras
• Cubos de excavadores

2. Hardox Series (Suecia)

Hardox is a globally recognized wear plate system developed for high-performance abrasive environments.

Características

• Excelente resistencia al impacto
• High toughness despite hardness
• Good processing and welding capability

Aplicaciones comunes

• Carrocerías de camiones volquete
• Heavy mining equipment
• Industrial wear liners

3. Serie NM (China Standard)

The NM series is one of the most common wear plate systems used in China.

“NM” generally refers to wear resistant steel plate.

Características

• Similar performance to AR grades
• Ampliamente utilizado en la fabricación industrial.
• Good cost-performance balance

4. XAR Series (Alemania)

XAR wear plates are European high-hardness abrasion resistant steels.

Aplicaciones

• Cement equipment
• Earthmoving machinery
• Sistemas de manipulación de materiales a granel

5. JFE EH Series (Japón)

Japanese wear-resistant steels are known for stable quality and impact resistance.

Typical Uses

• Maquinaria industrial
• Steel mill liners
• Equipos de minería

6. Acero de desgaste con alto contenido de manganeso (mn13)

Unlike quenched wear plates, Mn13 is a work-hardening wear steel.

Características

• Surface hardens under impact
• Excelente resistencia al impacto
• Good for high-impact wear conditions

Aplicaciones

• Mordazas de triturador
• Cruces ferroviarios
• Impact liners

8. Selection Considerations

Different abrasion resistant wear plates are selected based on:

• tipo de desgaste (corredizo, impacto, ranurado)
• Required hardness level
• Weldability requirements
• Processing complexity
• Entorno de servicio

Higher hardness usually improves wear resistance, while lower hardness grades often provide better toughness and easier fabrication.
