Product Description

JFE EH 400 Plates Wear Resistant Plate Structure Steel Storage：
When storing, please avoid bending or twisting the steel plate. Cracks can cause corrosion. To prevent pitting and rusting caused by this, use a waterproof cloth. To remove the moisture inside the waterproof cloth, please ventilate frequently.

Wear Resistant Steel Plate JFE EH400 has a hardness value ranging from 370 to 430 HBW on the Brinell scale. It features high wear resistance, high strength, good toughness, good machinability, and certain corrosion resistance.
