The Cleveland-Cliffs Mansfield Works plant began operating in 1955. It was previously owned by AK Steel but was transferred to Cleveland-Cliffs after Cleveland-Cliffs bought AK Steel in 2020 for $1.1 billion.[1]

In 2004, the facility was investigated by the EPA for improper disposal of residual materials.[2]

In 2018, a worker died after heavy material crushed him.[3]

In January 2020, a worker at the plant was injured after an accidental explosion at the facility.[4] In April 2020, AK Steel temporarily idled the plant due to low demand for steel.[5]
