Vim li cas Cov Khoom no tseem ceeb rau koj daim ntawv thov
- Hardness (480-550 HBW): Txuas ncaj qha rau hnav lub neej-NM500 liners kav ntev li 3–5x ntev dua li cov hlau me me hauv ib puag ncig abrasive (xws li, thee chutes, crusher liners).
- Tensile/yield zog: Txhawb nqa cov phaj nyias nyias (txo qhov hnyav los ntawm 20-30% piv rau cov tuab tuab tuab) thaum tuav cov kav ntev, txhawb nqa cov khoom siv thauj khoom thiab roj efficiency.
- Impact Zog: Qhov tseem ceeb rau cov ntawv thov nrog kev thauj khoom sai sai (piv txwv li, pob zeb cuam tshuam rau ntawm lub tsheb bulldozer hniav) - NM500 zam kev tawg, txo lub sijhawm poob los ntawm kev ua tsis tiav.
- Elongation & Weldability: Simplifies fabrication (txiav, dabtsi yog khoov, welding) thiab ntawm -site installation, txo nqi zog thiab lub sij hawm ntawm qhov project.
