Hardness vs Toughness Trade-Off in Wear-Resistant Steels: NM400 wear-resistant steel plate sweet spot zone
In wear-resistant material selection, engineers constantly face a core contradiction: higher hardness improves abrasion resistance, but lower toughness increases the risk of cracking under impact. Finding the “sweet spot” between hardness and impact toughness is the key to achieving long service life, stable performance, and cost efficiency in real industrial...
