According to GOST 5949 Note. The norms of mechanical properties apply to samples taken from steel with a diameter or thickness of up to 60 mm.
For steel with a diameter or thickness of st. 60 to 100mm, a reduction in elongation of 1abs.% Is allowed,
relative narrowing by 5abs.% and impact strength by 4.9 J / cm2 at a rate of less than 78.4 J / cm2 and by 9.8 J / cm2 at a rate of 78.4 J / cm2 or more.
For steel with diameter or thickness sv. 100 to 150mm is allowed to decrease the relative elongation by 3abs.%
a relative narrowing of 10 abs.% and impact strength of 9.8 J / cm2 at a rate of less than 78.4 J / cm2 and at 14.7 J / cm2 at a rate of 78.4 J / cm2 or more.
