Austenitic stainless steels are often used for a materials in the construction of machines and equipment for agricultural and for industrial construction. One of the most important factors constructional material is corrosion resistance. Equipment with austenitic stainless steel can be easy join by quickly welding at a not to high construction price, but one with the serious problem in aggressive environment is their corrosion resistance.
A few corrosion processes in crevices and awkward corners can be avoided at the design stage (low roughness parameters, round-section and other). But still the construction material is exposed to corrosion. These steels often come into contact with an aggressive environment based on nitric acid.
The main aim of this research is to investigate corrosion resistance in different time (48, 96, 144, 192, 240, 288, 336 hours). For this used weight loss of test samples and its profile roughness. The research was conducted on austenitic stainless steel in grade in Nitrate acid at 333 K.
Corrosion tests confirmed that the research this steel in 65% nitrate acid as a corrosive environments is characterized through proportionate to time corrosion process whose measure may be surface roughness. In industrial practice roughness parameters for all the research times can be used for determine the stage and size of steel corrosion.

The article presents the main trends in Rapid Prototyping and Smart Engineering. The potential of Central European regions was demonstrated and characterized on the mentioned basis of which e-learning trainings were developed. Based on the implemented international project “3DCentral – Catalyzing Smart Engineering and Rapid Prototyping”, selected conclusions from the implementation of the training program are presented.
The article presents the essence and significance of risk management processes in the project, as the key field for successful completion of the project, in the field of project management. Based on literature review, the methods and standards of risk management in the project as well as standards related to process safety were defined. The risk management process according to the PMBoK methodology was discussed as an example of an international project entitled 3DCentral – Catalyzing Smart Engineering and Rapid Prototyping.
The paper presents selected problems of design of machinery retrofit in Industry 4.0 era. In order to show the diversity of applications of new technological achievements, the case of radar revitalization as a museum exhibit has been shown. Ensuring functional safety and staff work safety has been changed into the safety of visitors to the museum and bystanders. Different approaches to the implementation of the safe stop function in both the internal adjustable frequency drive and the safety terrain zone are presented in the article.
