1.4581 (DIN EN 10213-4 : 1996-01) GX5CrNiMoNb19-11-2 1.4581 DIN EN 10213-4 : 1996-01 DIN EN 10213-4 : 1996-01 replaced by DIN EN 10213 : 2008-01 With DIN EN 10213-1 : 1996-01 partial replacement for DIN 17445 : 1984-11 Replaced Germany GX5CrNiMoNb19-11-2 1.1.2 1)
1) Remark: The austenitic material GX5CrNiMoNb19-11-2 is equivalent to trademark G-X 5CrNiMoNb 18 10 acc. to DIN 17445-84. This ic-resistant material is used for fittings, pumps, agitators, tanks in chemical industry, in cellulose, rayon staple, textile, color and rubber industry. It is weldable without preheating and heat after treatment. A special stabilization annealing in a range from 550 to 600 °C. is accordable in order to improve the corrosion resistance.
