    Abstract. The influence of ferrite grain size, perlite, sulfur (sulfides), manganese, and phosphorus content on yield strength, critical brittleness temperature, and viscous crack propagation on eight shelves of bent-welded profiles of square and rectangular cross sections according to the regulatory document on steel profiles for building structures was studied using the correlation and regression analysis technique. The influence of ferrite grain size, perlite and sulfur content on the yield strength of 17G1C steel is considered using the ranking method. It is shown that despite the noticeable plastic deformation that occurs during the manufacture of bent-welded profiles, all the profiles studied, with the exception of one profile, comply with the standard for steel structures for structures of the first and third groups. The effect of the introduction of amendment No. 1 to the standard for steel profiles on improving the reliability and mechanical safety of bent-welded profiles that cause metal embrittlement is considered.
    Keywords: low-alloy steel 17G1C, critical brittleness temperature, impact strength, viscous crack propagation, ferrite grain size, perlite and sulfur content, plastic deformation, closed welded profiles
