Arc welding of stainless steels for demanding working conditions
Matějíček, Josef ; Hála, Michal (referee) ; Kubíček, Jaroslav (advisor)
Bachelor thesis introduced deals with Arc welding of stainless steel. With welding technology, used by company DIAMO, the connected pipes, flanges and plates are for guiding the Sodium Sulphate solution, which is obtained as by-product in production of Uranium. Corrosive attack and weld cracking occurs in the short period of time due to the chemical reaction. Based on information about materials, used additional materials and welding technology used I have evaluated materials with susceptibility to the corrosion and the formation of hot cracks. Using tests and calculations I have examined the susceptibility of austenitic stainless steel to intergranular corrosion. Austenitic-ferritic stainless steel was also used as a theoretical solution for larger spectrum of materials. After calculations and evaluations of the trial tests I have conducted discussion and recommendations for use in practice.

Manufacture and use of high-alloy steel castings
Koláček, David ; Kaňa, Václav (referee) ; Pernica, Vítězslav (advisor)
This thesis includes material issue-knowledge of stainless steel cast. In the first part of thesis are analysed the causes of corrosion, its impact on metal material and is explained the creation of corrosion resistance.The next part of thesis introduces separation of stainless steel based on structure and chemical composition, explains its properties and its possibilities of using in practise. The thesis also explain some production processes of the stainless steel cast. In the final part of thesis are illustrated some possibilities of using stainless steel in practise.

Manufacture and properties of high-alloyed Cr steels
Invald, David ; Haluza, Jakub (referee) ; Záděra, Antonín (advisor)
The bachelor thesis deals with the issue of properties, production, distribution, and use of high-alloyed chromium steels. One of the main part of the thesis is devoted to corrosion because corrosion resistence is important properties of high-alloyed chromium steel. The last part deals with high-alloy steels production and equipment for steel production.

Shoulder milling of stainless steels
Holeček, Václav ; Kalivoda, Milan (referee) ; Humár, Anton (advisor)
The bachelor thesis talks about sholder milling of stainless steel. The first part deals with the general thesis including shoulder milling with the of division milling tools. Further stainless steel is described including its machinability. The main part is analyses mills for shoulder milling made by world´s producers, which are finally eva-luated from differen points of view.

Stainless steels
Chára, Tomáš ; Kalina, Lukáš (referee) ; Zmrzlý, Martin (advisor)
This thesis deals with stainless steels. The theoretical part describes the mechanisms and types of corrosion. Then the thesis deals with the properties, distribution and manufacture of the stainless steels and a brief description of the XPS method used for the practical part. In the recherche section summarizes the ways of using the XPS method for determining the quality of the passive layer of stainless steels eaten in different environments. Practical task was to compare the quality of the passive layer of stainless steels resulting from natural and chemical passivation.

Progressive anticorrosive metal materials
Bombera, Mojmír ; Kaňa, Václav (referee) ; Šenberger, Jaroslav (advisor)
This bachelor thesis is aimed at stainless steels problem. At the beginning history of steel and one of the biggest issue of steel, corrosion is described. Next part show basic type of stainless steels, their material characteristic, properties and possibilities of usage. After that metallurgy of stainless steels and process follows. In last topic of this bachelor work samples of usage in various branges are presented.

Korozivzdorné oceli a jejich využití
Studený, Petr
Presented bachelor's thesis is aimed to research into properties and application of corrosion-resistant steel. There are briefly described types of corrosion and methods, how to protect machines against them, in theoretical part. Thesis is also focused on qua-lities and classification of this steel. In the practical part of thesis there is thorough description of manufacturing pro-cess, which leads to origination of product made from corrosion-resistant steel in Schwer fittings s.r.o. This company have worked at this field since 1998.
