Fe is the basis.
According to GOST 5781-82, the addition of Ti (titanium) is allowed from the calculation of its mass fraction in the finished rolled product 0.01-0.03%, the addition of Ti (titanium) is allowed from the calculation of its mass fraction in finished rolled products made in coils of 0.01- 0.06%.
According to GOST 10884-94 in steel, intended for the production of reinforcing steel classes AT600, AT600C, At600K and At800, it is possible to increase the mass fraction of sulfur and phosphorus to 0.045%. In steel, intended for the production of reinforcing steel classes Am600C, At800 and At800K, the mass fraction of carbon should be 0.28-0.33%, and the mass fraction of manganese 0.90-1.20%.
