Wear-resistant steel plate is a high-strength steel made through a special heat treatment process. Its surface hardness can reach HB400-600, which is 3-8 times more wear-resistant than ordinary steel plates. It is widely used in harsh working conditions such as mining machinery and engineering equipment.

Purchase technical guide
Three key points for quality identification
Hardness test: Use Leeb hardness tester for multi-point detection, surface hardness fluctuation should be ≤5%
Metallographic analysis: martensite content must be >85%, carbide is evenly distributed
Certification documents: MTC material report + CE/PED certification must be provided
