Fe is the basis.
According to TU 108-1151-82, the content of Ti% = 5C% is 0.7%. Deviations are allowed: titanium ± 0.50%, chromium ± 0.30%, silicon + 0.10%, sulfur and phosphorus + 0.0050% each. At the request of the customer, yttrium and cerium can be (in the calculation) in the composition of steel in the amount of 0.001-0.1% and 0.03-0.10%, respectively.
