In the demanding world of heavy machinery, mining, and steel production, component failure is rarely due to a lack of bulk strength. Instead, it is almost always a surface problem: abrasion, erosion, or galling. This is where the specification enters the workshop floor.
Note: In engineering contexts, "MSH-45" is not a universal global standard (like ISO or SAE). It is typically an internal company specification or a specific lot code for a thermal spray powder. The following article is based on the most common interpretation of this nomenclature in industrial surface engineering. msh_45
