Ti is the basis.
According to OST 1 92077-91 the total allowable content of Cu + Ni ≤ 0.10%, including Ni ≤ 0.08%. The amount of other impurities (not listed in the table, including copper and nickel) ≤ 0.30%. The content of hydrogen in ingots should be ≤ 0.006%. Addition of modifying additives in an amount of ≤ 0.003% is allowed. The alloy modified with boron has an additional index "B".
For pipes of group A in accordance with GOST 21945-76, the maximum mass fraction of hydrogen in the alloy is set to 0.006%.
