According to TU 14-3-1630-89 and TU 14-242-275-89 the chemical composition is given for steel grades 04Х14Т3Р1Ф-ВИ; 04Х14Т3Р1Ф-ПТ. In the finished product, deviations in chemical composition are allowed: by carbon +0.01%, by chromium + 0.50%, by boron +0.10%, by titanium + 0.50%, by vanadium +0.10%, by aluminum +0.20%, for silicon +0.10%, for nickel +0.15%. Mass fraction of residual elements in accordance with GOST 5632. REM are introduced in an amount up to 1.5 kg / ton by calculation and chemical analysis are not determined. For alloying steel used ferroboron, smelted from boron-10 boron-containing raw materials uncharted Dalnegorsk association "Bor".
According to TU 1315-088-00212179-2012 the chemical composition is given for steel grade 04H14T3R1F. The remaining notes are the same.
According to TU 14-1-3689-83, the chemical composition is given for steel grades 04Х14Т3Р1Ф (ЧС82), 04Х14Т3Р1Ф-ВИ (ЧС82-ВИ) and 04Х14Т3Р1Ф-ПД (ЧС82-ПД). Residual content of elements and deviations in chemical composition - in accordance with GOST 5632. REM is introduced in an amount of 0.5-1.00 kg / ton by calculation and chemical analysis is not determined.
According to TU 14-1-4599-89, the chemical composition is given for the steel grades 04H14T3P1F-VI (CS82-VI), 04H14TZR1F-PT (CS82-PT) and 04H14T3P1P-PS (CS82-PS) and 04X14T3P1F- . Deviations in chemical composition are allowed in the finished product: carbon +0.010%, chromium + 0.50%, boron +0.10%, titanium + 0.50%, vanadium +0.10%, aluminum + 0.20%, for silicon +0.10%, for nickel + 0.15%. Mass fraction of residual elements and limiting deviations according to GOST 5632. REM are introduced in an amount of 1.5 kg / ton by calculation and chemical analysis are not determined. For alloying steel used ferroboron, smelted from boron-10 boron-containing raw materials uncharted Dalnegorsk association "Bor".
According to TU 14-1-5604-2010 the chemical composition is given for steel grade 04H14T5R2F (ChS82M). The chemical composition of steel grade 04H14T3R1F (CHS82) is characterized by the following contents: carbon 0.02-0.06%, boron 1.30-1.80%, titanium 2.30-3.50%, vanadium 0.15-0.30% , the content of the remaining elements is the same. For steel alloying, ferroboron is used, smelted from boron-containing raw material, which is not diluted in boron-10, and passed mass-spectrometric control to a percentage of boron-10. The procedure for determining d. agreed with ZAO "Tewel-Invest-Technology". The introduction of REM by calculation is permissible for 0.10-0.40% and it is not determined by chemical analysis. The ratio of titanium content to boron content should be within the range of 1.90-2.20. Mass fraction of residual elements - according to GOST 5632.
