Fe is the basis.
According to GOST 6713-91, nitrogen content is allowed up to 0.012%. In steel, deoxidized with aluminum, the residual content of acid-soluble aluminum should be not less than 0.020%. The use of other deoxidizers is allowed. In the rental for bridge structures of the northern version, the mass fraction of sulfur should not exceed 0.030%, phosphorus - not more than 0.025%. Manufacture of electroslag remelting steel is permitted. The analysis of rolled products for chromium, nickel, arsenic and nitrogen is made at the request of the consumer. In the finished rolled steel of 16D with a mass fraction of carbon 0.10-0.12%, an increase in the mass fraction of manganese to 0.80% is permissible.
