Wear Resistant Steel Plate Manufacturer | NM400 NM500 Hardox 400

High-Quality Wear Resistant Steel Plate – Manufacturer & 供应商

Wear resistant steel plate is a high-strength specialty steel processed through quenching and tempering, featuringextremely high surface hardness and excellent abrasion resistance. Compared to conventional mild steel, wear resistant steel plates offer3 到 5 times longer service life, significantly reducing equipment maintenance costs and downtime.

Qida Metal is a professional supplier of the full range of wear resistant steel plates, coveringNM series (NM360, NM400, NM450, NM500) , VRN series (VRN400, VRN450, VRN500) , Weldox series (Weldox 700, Weldox 900) , as well asHB series (HB400, HB500) 和Hard400 – all available in equivalents to internationally recognized brands. Our products comply with美国材料试验协会, 他, 从, 国标 and other international standards.

主要特点 & 优点

Ultra-High Surface Hardness: Brinell hardness ranges from HB360 to HB530, allowing you to select the optimal grade for your working conditions. HB400 grade delivers approximately twice the service life of mild steel, while HB500 achieves 3 到 3.5 times.
Excellent Abrasion Resistance: Specifically engineered for high-wear applications, significantly extending the service life of buckets, liners, chutes, and other wear parts.
Superior Impact Toughness: Produced through quenching and low-temperature tempering, combining a high-strength matrix with a hardened layer for both wear resistance and impact resistance.
Excellent Workability: Supports cutting, 弯曲, 焊接, 钻孔, and punching – customizable to customer drawings.
良好的焊接性: Plates are shotblasted and primed to maintain good weldability and laser cutting performance.
Wide Range of Specifications: 厚度 0.2mm – 100mm, 宽度 1000mm – 2500mm, length 2000mm – 12000mm.
Full Grade Coverage: NM360, NM400, NM450, NM500, NR360, NR400, B-HARD360, B-HARD400, B-HARD450, 和更多.
