Title:
CORROSION-RESISTANT AND WEAR-RESISTANT STEEL PLATE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/022531
Kind Code:
A1
Abstract:
Disclosed in the present disclosure are a corrosion-resistant and wear-resistant steel plate and a manufacturing method therefor. The steel plate comprises, in percentages by weight: C: 0.15% ≤ C ≤ 0.25%; Si: 0.10% ≤ Si ≤ 0.50%; Mn: 0.50% ≤ Mn ≤ 1.50%; Mo: 0.01% ≤ Mo ≤ 0.50%; Nb: 0.005% ≤ Nb ≤ 0.050%; V: 0.01% ≤ V ≤ 0.10%; Ti: 0.005% ≤ Ti ≤ 0.050%; Al: 0.010% ≤ Al ≤ 0.060%; Cr: 2.00% ≤ Cr ≤ 5.00%; B: 0.0005-0.0050 wt%; and P: 0.010% ≤ P ≤ 0.030%. In addition, the steel plate further comprises one or more of Cu: 0.10% ≤ Cu ≤ 0.40%, Ni: 0.20% ≤ Ni ≤ 1.00%, RE: 0.01% ≤ RE ≤ 0.10%, and Sb: 0.01% ≤ Sb ≤ 0.20%, with the balance being Fe and inevitable impurities. The manufacturing method for the steel plate comprises the steps of: (1) a smelting and casting step; (2) a heating step; (3) a rolling step; and (4) an online cooling step. The steel plate of the present disclosure has both good acid and alkali resistance and wear resistance.
