“…The effect of low temperature nitriding on corrosion behaviour has been studied especially for AISI 300 series stainless steels [18,20,[22][23][24][25][26][27][28][29]; a few researches have been also performed on AISI 200 series stainless steels [20,29,30]. Very few studies have regarded nickel-free austenitic stainless steels [31,32].…”

“…Os aços inoxidáveis austeníticos encontram ampla aplicação na indústria devido à sua notável resistência à corrosão, boa conformabilidade e apreciáveis propriedades mecânicas (TANG;YANG, 2022). Esta classe de aços é dividida em duas categorias distintas: a série 300 (Cr-Ni), caracterizada por elevadas quantidades de cromo e níquel, e a série 200 (Cr-Mn), na qual o níquel é parcialmente substituído por manganês e nitrogênio (GAO;ZHENG, 2015). Devido à elevação do preço do níquel, os aços Cr-Mn têm sido objeto de interesse crescente nos últimos anos, visto que em média, custam consideravelmente menos que os aços inoxidáveis Cr-Ni (OSHIMA; HABARA; KURODA, 2007).…”

Na indústria alimentícia os aços inoxidáveis Cr-Ni são amplamente reconhecidos por suas propriedades satisfatórias frente às condições de serviço. Por razões de custo, eles vêm sendo substituídos pelas ligas Cr-Mn. Aliado a isso, novas composições químicas dessa família surgiram e estão sendo comercializadas, porém, elas não se enquadram nos padrões de normas técnicas internacionais. Assim, esse artigo tem o objetivo de apresentar uma revisão sistemática sobre a utilização de aços inoxidáveis Cr-Mn em ambientes comumente encontrados na indústria alimentícia. Para tanto, foi feita uma pesquisa bibliométrica utilizando a técnica de science mapping aliada ao bibliometrix. As buscas foram realizadas nas bases de dados da Web of Science e Scopus utilizando as palavras-chave: "chromium-manganese stainless steel" OR "Cr-Mn" OR "low-nickel stainless steel" OR "non-standard stainless steel" OR "borderline stainless steel" OR "counterfeit stainless steel" OR "AISI 201" e “corrosion” OR "food contact" OR pitting OR "weight loss" OR "simulated food" OR "acetic acid". Resultaram dessa busca 268 artigos, publicados entre os anos de 2005 e 2023, os quais foram analisados. Em suma, verificou-se que os aços Cr-Mn normatizados têm demonstrado seu uso seguro para aplicações na indústria alimentícia. Quanto às ligas Cr-Mn não normatizadas foram encontrados poucos artigos relacionados ao uso no ramo alimentício. No entanto, esses estudos apontaram que essas novas ligas apresentam restrições em ambientes corrosivos, precisando ter cautela em aplicações na indústria alimentícia.

In order to improve the related properties of H13 die steel, researchers have tried various surface modification methods, such as plasma nitriding, ion implantation, laser surface treatment and carbonitriding [13][14][15][16][17], among these technologies, plasma nitriding is currently widely adopted in real application to improve the wear resistance [18][19][20].…”

QPQ salt bath treatment of H13 steel was conducted by nitriding at the same temperature of 565 ℃ for various times, followed by the same post-oxidation process. Optical microscope, microhardness tester, X-ray diffraction and wear resistance tester were employed to characterize the microstructure, phase constituents, micro-hardness and wear resistance of the treated specimens. The results showed a compound layer mainly composed of ε-Fe2-3N and diffusion layer were formed during salt bath nitriding and a thin oxide layer composed of Fe3O4 was formed by postoxidation, and the compound layer thickness increases with the nitriding time. The maximum surface hardness value of 1441 HV0.3was obtained after nitriding at 565℃ for 150 min, which is as three times high as that of untreated sample. Meanwhile the wear resistance of H13 steel is significantly improved by QPQ treatment, 150 min is the optimum nitriding time to improve the surface hardness and wear resistance of H13 steel.Keywords: QPQ treatment, H13 steel, Wear resistance, Hardness, Microstructure 1 Introduction H13 steel is a kind of widely used hot die steel due to its good mechanical properties at elevated temperature and moderate cost [1][2][3]. In real application, hot working tools are generally repeatedly subjected to high temperature and heavy loads [4,5], these severe conditions tend to result in failure of the tools due to wear or plastic deformation etc. [6][7][8][9][10][11][12]. In order to improve the related properties of H13 die steel, researchers have tried various surface modification methods, such as plasma nitriding, ion implantation, laser surface treatment and carbonitriding [13][14][15][16][17], among these technologies, plasma nitriding is currently widely adopted in real application to improve the wear resistance [18][19][20]. Unfortunately, it generally takes dozens of hours to obtain the required properties, which brings out low efficiency and high consumption of energy [21,22]. It has been reported that QPQ treatment is an effective surface modification technology, which has been widely used in manufacturing field to improve the wear and corrosion resistance of the components [23,24], since a compact oxide film can be formed on the top of a nitriding layer on the metal surface after QPQ treatment. More importantly, comparing with plasma nitriding, QPQ treatment has significant advantage of much higher efficiency; it generally takes only several hours for the whole process.
