Pre-oxidation-induced MnCr2O4/Cr2O3 scales in HP steels and their role in carburization resistance

Key Points

• Carburization resistance increases in HP steels with pre-oxidation treatment, leading to enhanced scale formation.
• Key evidence shows improved resistance in manganese chromite and chromium oxide scales across multiple tests.
• Assessment using high-temperature experimental setups revealed scales altered by pre-oxidation improve performance.
• Implications indicate a better understanding of protective scales could enhance steel durability under harsh conditions.
