Chrome Hardfacing Wear Plate

In industrial work that involves heavy equipment, wear on equipment appears as a main factor that decreases production efficiency and increases maintenance costs. Shandong Qishuai Wear-Resistant Equipment Co., Ltd. examines issues that clients encounter. The company presents Chrome Hardfacing Wear Plate to address this. The method involves overlay welding that deposits a layer with high hardness and high wear resistance using chromium alloy onto a substrate of low-carbon steel or low-alloy steel with resilience. This produces a material that combines features. The design with two metals combines the hardness that the wear-resistant layer provides with the toughness and plasticity that the substrate presents. This makes it a choice for use in conditions involving severe wear from materials. Whether in industrial contexts that present harsh conditions or in uses requiring particular features for appearance, the wear-resistant plates show performance that addresses different requirements.

Product Features

Wear Resistance:

The layer that resists wear contains chromium at 25-30% and carbon at 4-5% in composition. This produces carbide particles that contain Cr₇C₃ and present hardness. These particles occupy a volume fraction exceeding 50%. The chromium alloy overlay wear plate shows macro hardness of HRC 58-65 that results from this. The resistance to wear exceeds that of standard low-carbon steel by over 20 times. This allows resistance to erosion from materials with high intensity and wear from abrasion.

Impact Resistance:

The products differ from castings that resist wear and use a single material. Products use a substrate of low-carbon steel that provides ductility. When external forces that produce impact act on the material, the substrate functions to absorb energy at a substantial level. This prevents fracture and detachment that impact forces produce. The plates can withstand loads from impact in uses involving high drops such as hoppers.

Convenient processing:

Chromium alloy overlay wear plates allow cutting, bending, rolling and welding similar to ordinary steel plates. Installation onto equipment that is already in use can occur according to requirements through bolting, stud welding or direct welding. This reduces the complexity that maintenance and installation at sites present.

Heat and Corrosion Resistance:

The layer with high chromium shows strong resistance to high temperature and resistance to oxidation. This maintains high hardness and resistance to wear even in conditions with high temperature of five hundred to six hundred degrees. The layer also provides some degree of prevention of rust and resistance to corrosion. This makes it particularly appropriate for use with materials that contain high humidity or that show weak acidity or weak alkalinity.
