Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Experiments on quantitative evaluation of fatigue strength showed that St5ps and St5sp carbon steels with А400 strength class can be fully applied for erection of constructions and buildings having cyclical loads during operation.Study of corrosion resistance of hardened carbon steel in comparison with hot-rolled alloy steel consists in difference in structures and hence, difference in intensity of electric and chemical processes featuring presence of steel in concrete.Structure of St5sp steel with А400 strength class in surface area has significantly less corrosion rate than ferritic-perlitic structure of 35GS steel with А400 strength class.
