Nitrogen ions at various energy and dose have been implanted into the surface of AISI 420 martensitic stainless steel. • Nanohardness was improved by a factor of 2.3 when the implant energy and dose were 50 keV and 5 × 10 16 cm − 2. 5 × 10 17 cm − 2 should be the suitable dose for the improvement of wear resistance.
In this paper, low-energy proton irradiation experiments with different cumulative fluences were performed on samples of AISI 420 stainless steel that were either annealed or tempered at 600 or 700 C.
Kurzbeschreibung. Der Werkstoff 1.4034 oder AISI 420 weist durch seinen höheren Kohlenstoffgehalt eine gute Härtbarkeit auf. Durch seinen hohen Chromgehalt liefert er ebenfalls eine gute Beständigkeit gegen Korrosion. Dieser Werkstoff wird häufig bei der Herstellung von Schneidwerkzeugen, chirurgischen Instrumenten und Wälzlagern …

In this research work, low-temperature carburizing of AISI 420 martensitic stainless steel was conducted at 460 °C for different amounts of time using an acetone source. The microstructure and phase structure of the carburized layers were characterized by optical microscope and X-ray diffraction. The properties of the carburized layers were …
در این مقاله رفتارخوردگی تنشی فولادهای زنگ نزن مارتنزیتی AISI 420 و زنگ نزن آستنیتی AISI 316L در محیط کلریدی تحت کرنش های کم و اثر سه عامل دما، محیط آزمون (کلرور منیزیم) و نرخ کرنش بر مقاومت خوردگی تنشی فولاد مذکور مقایسه شده است.
Decarburization deteriorates the surface mechanical properties of steel. It refers to the loss of carbon from steel's surface when exposed to an open-air environment in elevated-temperature conditions. Despite the short interaction time and fast thermal cycle of the laser surface-hardening process, decarburization may still occur. This paper …
Figure 2 (a) shows the XRD patterns of AISI 420 specimens nitrided at different temperatures. It can be seen that no precipitation of CrN phase was found in all specimens. The XRD patterns of the untreated specimen shows the standard α′ phase peaks (JCPDS file 44–1292). phase peaks (JCPDS file 44–1292).
SAE steel grades. The SAE steel grades system is a standard alloy numbering system (SAE J1086 - Numbering Metals and Alloys) for steel grades maintained by SAE International . In the 1930s and 1940s, the American Iron and Steel Institute (AISI) and SAE were both involved in efforts to standardize such a numbering system for steels.
