Chemical Interaction Between Heat-Resistant Steel and S93-3M Mark Electrovacuum Glass: An Investigation

Chemical Interaction Between Heat-Resistant Steel and S93-3M Mark Electrovacuum Glass: An Investigation

This articles discusses the use of 20Kh23N18T mark stainless steel and its foreign analogue AISI 310S instead of 12Kh18N10T steel as a material for making shaping dies used in the manufacture of glass insulators made from S93-3M mark electrovacuum glass. Such insulators are widely used in the radio-...

Description
Summary:This articles discusses the use of 20Kh23N18T mark stainless steel and its foreign analogue AISI 310S instead of 12Kh18N10T steel as a material for making shaping dies used in the manufacture of glass insulators made from S93-3M mark electrovacuum glass. Such insulators are widely used in the radio-electronic industry as housings for magnetically operated contacts. It is shown that at operating temperatures a chemical interaction occurs between both grades of steel and S93-3M grade glass, which results in deterioration in the product quality on account of the appearance of a large number of gas bubbles in the product. It was ascertained that the additional heat treatment makes it possible to diminish the consequences of this chemical interaction, and thereby improve the quality of the resulting product.
