GOST 4543-71. Structural alloy steel bars. Specifications

It is a low-alloy constructional steel of pearlite class. The paper presents a theoretical and experimental research activity carried out in order to improve the properties of the 40H steel. The results permit the selection of the right heat-treatment parameters that offer the best combination between the yield strength, tensile strength, elongation, necking, impact strength at low temperature and hardness, in order to obtain a better behavior of the material for production tubing pipes in accordance with GOST Tubing pipes and couplings for them, for strength group M and L.
