耐摩耗鋼板
Wear resistance steel plates are essential materials for industries with high abrasion and impact loads.
When selecting a grade, 考慮する:
-
Hardness and impact toughness;
-
Thickness and dimensions;
-
Origin and standards (international or Chinese equivalents);
-
Processability and weldability.
Chinese grades like NM500, MN13, CrC/CCO offer cost-effective solutions with high performance, suitable for most industrial applications.
- 説明
Wear resistance steel plates are specialized steels designed for high hardness and superior resistance to abrasive and impact wear.
それらは広く使用されています 採掘, セメント, 冶金, and construction industries のために バケツ, ライナー, スクリューコンベア, ホッパー, and crushers.
