SHEET FROM TI CONTAINING FERRITIC STAINLESS STEEL HAVING GOOD IMPACT VISCOSITY, AS WELL AS A FLANGE Russian patent published in 2020 - IPC C22C38/00 C22C38/18 

FIELD: metallurgy.

SUBSTANCE: invention characterizes a sheet of Ti containing ferritic stainless steel containing, wt %: 0.003 to 0.030 C, 2.0 or less Si, 2.0 or less Mn, 0.050 or less P, 0.040 or less S, from 10.0 to 19.0 Cr, 0.030 or less N, 4(C+N) or more and 0.80 or less Ti, and from 0.010 to 0.20 Al, as well as, if necessary, 1.50 or less Mo and 0.0030 or less B, the balance is iron and unavoidable impurities. Proposed sheet contains extraction residue R, extracted by electrolytic extraction method, content of which satisfies the inequality R> 5.0C+4.4N−0.025, where C and N are content of carbon and nitrogen in wt %.

EFFECT: technical result is obtaining sheet from ferritic stainless steel containing Ti, having good impact viscosity.
