Abstract (English):
The complex effect of the amount (ferrite + perlite) and the average grain area on the 20gl low-alloy cast steel section of car castings based on statistical and microstructural analyses of open-hearth and electric arc melting on the increase in the impact strength of KCV-60>2.0 is considered.

Keywords:
statistical and microstructural analyses, impact strength, side frame, spring beam, 20gl steel
