Title:
RARE EARTH-CONTAINING NM600 WEAR-RESISTANT STEEL PLATE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/087882
Kind Code:
A1
Abstract:
The present invention relates to the technical field of steel production. Disclosed are a rare earth-containing NM600 wear-resistant steel plate and a preparation method therefor. The wear-resistant steel plate comprises the following chemical components and mass percentage: C: 0.21%-0.63%, Mn: 0.20%-1.00%, Si: 0.10%-0.30%, Cr: 0.15%-0.85%, Mo: 0.08%-0.75%, Ni: 0.70%-2.00%, Nb: 0.010%-0.060%, V: 0.010%-0.060%, Ti: 0.010%-0.040%, Alt: 0.020%-0.080%, B: 0.0008%-0.0030%, Ce: 0.0005%-0.0080%, P≤0.010%, S≤0.0020%, O≤0.0020%, N≤0.0040%, and the remainder is iron and unavoidable impurities. By adding a rare earth alloy into low-alloy high-strength wear-resistant steel, low-temperature impact toughness and plasticity are effectively improved without reducing the hardness and strength of the steel plate.
