Ti is the basis.
According to GOST 19807-91, the total content of other impurities is ≤ 0.30%. The mass fraction of hydrogen is indicated for ingots. In the alloy of PT-3B grade, the mass fraction of zirconium in total with other impurities should not exceed 0.30%. The mass fraction of chromium and manganese should not exceed 0.15% (in total). The mass fraction of copper and nickel should not be more than 0.10% (in total), including nickel not more than 0.08%.
For pipes of group A in accordance with GOST 21945-76, the maximum mass fraction of hydrogen in the alloy is set to 0.005%.
