Abstract (en)

[origin: WO2017182531A1] A reinforcement (7) for a breaker strip for a thermal bridge for building construction, characterised in that it is produced from austenitic or austenoferritic stainless steel, the composition of which, in % by weight, consists of: traces ≤ C ≤ 0.08%; 1.5% ≤ Si ≤ 4.0%; 4.0% ≤ Mn ≤ 10.0%; traces ≤ Ni ≤ 7.0%; 16.0% ≤ Cr ≤ 23.0%; traces ≤ Mo ≤ 2.0%; traces ≤ W ≤ 1.0%; traces ≤ Mo + W/2 ≤ 2.0%; traces ≤ Co ≤ 2.0%; traces ≤ Cu ≤ 3.0%; 0.10% ≤ N ≤ 0.25%; the remainder being iron, alloying elements other than those previously mentioned, and impurities resulting from production, the total of said other alloying elements and impurities not exceeding 1.0%, and none of said other alloying elements being present individually in an amount greater than 0.5%, and in that the thermal conductivity index IC calculated according to: IC = 22.2 + 2.1 (1 - IF/100) – 0.89 Si – 0.77 Ni - 0.44 Mn – 0.17 Cr - 0.16 Cu, where IF = 6.7 Cr + 5.7 Mo + 0.7 Si – 8,.6 Ni - 2.4 Mn - 0.5 Cu - 110 C – 150 N – 42.7 is ≤ 13.5. A breaker strip for a thermal bridge comprising said reinforcement.
