Fe is the basis.
According to GOST 17152-89 (ISO 7129-82), upon the manufacturer's agreement with the consumer, the profiles are made with the content of elements: C = 0.60-0.90%, Mn = 1.20-2.00%. The upper limits of carbon and manganese should not coincide. The austenitic grain size should not be larger than 5 numbers in accordance with GOST 5639.
