Microalloyed anchor steels with Nb, Cu, Ni, Sb, and C were prepared through vacuum smelting and hot rolling. Electrochemical measurements, slow strain rate tensile (SSRT) tests, and fracture morphology observations were used to study the electrochemical and SCC behavior in the simulated mine environment. The results proved that the microstructure of microalloyed steels varies slightly. Adding Ni, Cu, and Sb can improve the mechanical properties of the anchor steel, while reducing C content decreases tensile strength as a result of loss of the solution-strengthening effect. The addition of Sb, Cu, Ni, and reducing the content of C enhances the resistance to corrosion and SCC by mitigating anodic dissolution (AD), while adding Nb improves SCC resistance by inhibiting hydrogen embrittlement (HE). The combined addition of 1% Ni, 0.5% Cu, 0.05% Nb, 0.1% Sb, and 0.5% C presented the highest SCC resistance, which is a promising prospect for the development of high-performance, low-alloy anchor steels. The combined addition of 1% Ni, 0.5% Cu, 0.05% Nb, and 0.1% Sb resulted in the inhibition of electrochemical reactions and corrosion. As a result of the synergistic effect of the microalloy, both AD and HE mechanisms were simultaneously inhibited, which greatly enhanced SCC resistance.<\/jats:p>","DOI":"10.3390\/ma16175965","type":"journal-article","created":{"date-parts":[[2023,8,31]],"date-time":"2023-08-31T09:54:46Z","timestamp":1693475686000},"page":"5965","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Enhancing the SCC Resistance of the Anchor Steel with Microalloying in a Simulated Mine Environment"],"prefix":"10.3390","volume":"16","author":[{"given":"Hailong","family":"Du","sequence":"first","affiliation":[{"name":"School of Civil and Resource Engineering, University of Science and Technology Beijing, Beijing 100083, China"},{"name":"Technology Research Institute of Shanxi Jincheng Coal Group Co., Ltd., Jincheng 048000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Na","family":"An","sequence":"additional","affiliation":[{"name":"National Materials Corrosion and Protection Scientific Data Center, Key Laboratory for Corrosion and Protection (MOE), University of Science and Technology Beijing, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiyan","family":"Wang","sequence":"additional","affiliation":[{"name":"National Materials Corrosion and Protection Scientific Data Center, Key Laboratory for Corrosion and Protection (MOE), University of Science and Technology Beijing, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongliang","family":"Li","sequence":"additional","affiliation":[{"name":"School of Energy and Mining Engineering, China University of Mining and Technology-Beijing, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiyong","family":"Liu","sequence":"additional","affiliation":[{"name":"National Materials Corrosion and Protection Scientific Data Center, Key Laboratory for Corrosion and Protection (MOE), University of Science and Technology Beijing, Beijing 100083, China"},{"name":"Hebei Special Equipment Supervision and Inspection Institute, Key Laboratory of Safety Evaluation of Steel Pipes and Fittings for State Market Regulation, Shijiazhuang 050061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aibing","family":"Jin","sequence":"additional","affiliation":[{"name":"School of Civil and Resource Engineering, University of Science and Technology Beijing, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renshu","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Civil and Resource Engineering, University of Science and Technology Beijing, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yue","family":"Pan","sequence":"additional","affiliation":[{"name":"National Materials Corrosion and Protection Scientific Data Center, Key Laboratory for Corrosion and Protection (MOE), University of Science and Technology Beijing, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaogang","family":"Li","sequence":"additional","affiliation":[{"name":"National Materials Corrosion and Protection Scientific Data Center, Key Laboratory for Corrosion and Protection (MOE), University of Science and Technology Beijing, Beijing 100083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"441","DOI":"10.1038\/527441a","article-title":"Share Corrosion Data","volume":"527","author":"Li","year":"2015","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"357","DOI":"10.1016\/j.engfailanal.2019.03.022","article-title":"Investigations of Rock Anchor Corrosion and Its Influence Factors by Exhumations in Four Typical Field Sites","volume":"101","author":"Wang","year":"2019","journal-title":"Eng.
