Abstract
The paper considers the issue of the possible use of stainless steel grade 20Cr23Ni18 and its foreign analogue AISI 310S, instead of steel 12Cr18Ni10T, as a material for the manufacture of a shaping die in the production of glass insulators from electrovacuum glass grade G93-3M, widely used in the radio-electronic industry as cases for magnetic contacts. It is shown that at working temperatures there is a chemical interaction between both steels and glass of grade G93-3M, which leads to a deterioration in the quality of products due to the appearance of a large number of gas bubbles in it. It has also been shown that due to additional heat treatment it is possible to reduce the consequences of this chemical interaction, thereby increasing the quality of the resulting product.
