Comparable Grades of NM550 Steel
NM550 steel does not always have a strict one-to-one equivalent in international standards. The grades below are commonly referenced comparable wear plate grades from different markets and manufacturers.
| Country/Region | Common Comparable Grade | Notes |
|---|---|---|
| China | NM550 | Chinese GB wear plate grade |
| USA | AR550 | North American wear plate grade |
| Japan | EVERHARD-C550(EH550) | JFE abrasion-resistant plate grade |
| Germany | DILLIDUR 550 | Commercial wear-resistant grade |
| Sweden | Hardox 550 | SSAB severe-wear plate grade |
Note: Different suppliers and databases may cite different foreign comparison grades for NM550. Exact substitution should be confirmed by chemical composition, heat treatment condition, section size, and application requirements.
Chemical Composition of NM550 Steel
The chemical composition of NM550 steel gives it a strong combination of hardness, strength, and wear resistance. Carbon increases hardness, while manganese and silicon improve toughness and abrasion resistance. These properties make NM550 steel ideal for demanding applications.
