|Sheets and strips||В33||TU 108-1151-82|
According to TU 108-1151-82, the content of Ti% = 5C% is 0.8%. Deviations are allowed: by titanium ± 0.50%, by chroma ± 0.30%, by silicon + 0.10%, by sulfur and phosphorus + 0.0050% by each, by carbon + 0.010%. 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.
