耐摩耗性の鋼板を理解する: hardox400 vs. NM400
Overview of HARDOX 耐摩耗鋼板
HARDOX is a 耐摩耗鋼板 produced by SSAB OXELOSUND, a key division of the SSAB Swedish Steel Group. As the world’s largest manufacturer of 耐摩耗鋼板, SSAB supplies products to over 100 国. で 1999, the company established a representative office in Beijing, 中国, to serve industries such as cement and mining. の HARDOX series is widely recognized for its durability and performance.
HARDOX400 and NM400: Naming and Hardness
The naming conventions of ハードックス400 そして HARDOX500 are similar to domestic NM400 そして NM500 鋼板. The numbers (400–500) indicate the Brinell hardness of the steel. In contrast, “ニューメキシコ州” in NM400 and NM500 stands for “wear resistance.”
