Metallographic research into the quality of X15N27T3MR-VD steel wire (EP700-VD)

Abstract

The purpose of this paper is to report on the results of metallographic research into the quality of X15N27T3MR-VD steel wire (EP700-VD). The reason for the research was an oxidized zone with intergranular cracking which had been detected on the surface of the wire. To remove the defects, a variety of chemical methods were applied to the surface. As the research shows, after the chemical treatment methods such as winding springs, blowing them with corundum, etching in a mixture of HNO3 and HF, and electropolishing were applied to the surface, the defects were removed completely.

Hydrogen Embrittlement and Peculiar Prorerties of Determining the Concentration of Hydrogen in Structural Steels

“…Chrome, tungsten and molybdenum are very effective in suppressing hydrogen corrosion, since they form stable carbides. Titanium, vanadium, zirconium and niobium, as well as tantalum and thorium form highly stable carbides and actively eliminate hydrogen corrosion [1,4,8].…”

Study of the Steel Heat Treatment Mode for the Purpose of Increasing the Efficiency of Ultrasonic Control

“…Failure of the connecting element under load can lead to human casualties. In the best case, a breakdown of the connecting element destroys the structure, and long-term repair of the structure leads to high economic costs, both due to the need to replace damaged parts of the structure (capital costs), and indirectly due to equipment downtime [1][2][3][4][5].…”
