“…This can be associated with an oxide thickness increase, as previously reported [34,35]. Furthermore, the oxide film is composed of a bi-layer, an outer film with a Fe-enrichment at the surface, formed by FeOOH and Fe3O4, as well as an inner layer with a Cr-enrichment that can be formed by Cr2O3 and Cr(OH)3, as was previously described by Luo et al [36] and Wonneberger et al [37].…”

“…By forming protective oxidation layers (Cr 2 O 3 , FeCr 2 O 4 , SiO 2 , Fe 2 SiO 4 , etc. ), Cr [9][10][11] and Si [12] significantly improve the oxidation resistance of steel. Jae-Young Park et al [13] found that the oxidation of Fe-Si-Cr alloys at 650 • C produced a double-layer structure oxide with Cr 2 O 3 in the outer layer and SiO 2 in the inner layer.…”

The surface of hot stamping steel is severely oxidized during heating, holding, and transfer from the heating furnace to the stamping die in the production of traditional automotive parts. Coating-free hot stamping steel with Cr and Si elements exhibits excellent oxidation resistance during hot stamping without the protection of a surface coating. This paper investigates the oxidation behavior of three types of hot stamping steel at 800–1200 °C. The results show that although Cr-Si hot stamping steel performs excellently short-term (≤7.5 min) for oxidation resistance, its long-term (≥15 min) or high-temperature (≥1100 °C) oxidation resistance is much lower than that of the conventional hot stamping steel 22MnB5, affecting the production and surface quality control of the new coating-free Cr-Si hot stamping steel. By analyzing the oxidation kinetics and characterizing the structure of oxide layers in hot stamping steel, it was found that the structural change in the Cr and Si element enrichment layer between the oxide scale and the substrate varied in oxidation performance at different temperatures. When the oxidation temperature was below 1000 °C, the solid Cr and Si enrichment layer acted as a barrier to prevent the diffusion of Fe ions. When the oxidation temperature exceeded 1100 °C, the molten Cr and Si enrichment layer effectively adapted to the substrate and avoided blistering. Meanwhile, Fe2SiO4 penetrated the Fe oxide layer along the grain boundary and became a rapidly diffusing channel of Fe ions, contributing to a significant increase in the oxidation rate.

“…Stainless steels are widely used in aerospace, automotive, and chemical industries due to their high strength, good oxidation resistance, and corrosion resistance [ 1 , 2 , 3 , 4 ]. With the rapid development of technology and industry, welding and joining are applied to make complex stainless steel structures in order to meet pluralistic usage requirements [ 5 , 6 , 7 , 8 ].…”

The problem of stainless steel brazing is still the focus of scientific research. In this work, the Mn-based brazing filler was used to braze 1Cr18Ni9Ti and 1Cr21Ni5Ti stainless steel. The typical microstructure of the 1Cr18Ni9Ti/1Cr21Ni5Ti joint was analyzed in detail, and the interface structure of the joint was determined to be 1Cr18Ni9Ti/Mn(s, s)/1Cr21Ni5Ti. The brazing temperature and holding time were shown to have a great influence on the microstructure of the brazed joint. The tensile strength of brazed joints first increased and then decreased with the rising of the brazing temperature and the holding time. The maximum tensile strength was 566 MPa when the joints were brazed at 1125 °C for 15 min. The diffusion of Mn and Cr was an important factor affecting the quality of the joints. The diffusion distances of Mn and Cr at different brazing temperatures and holding times were measured, and the diffusion activation energy and diffusion coefficient were achieved by the Arrhenius equation.
