EN 10088-1 Grade X4CrNiMo16-5-1 quenched and tempered (+QT900)
EN 10088-1 Grade X4CrNiMo16-5-1 quenched and tempered (+QT900) introduction
Material X4CrNiMo16-5-1 is comparable to X 4 CrNiMo 16 5 acc. to SEW400 : 1991-02. This material is a martensitic stainless steel for machine engineering, for pumps, fittings, compressors as well as for shipbuilding. It shows good corrosion resistance and cryogenic toughness up to -200 °C. The steel has high corrosion resistance especially to water, weak acids and bases, oxidizing acids (nitric acid) and low chloride containing media.
Equivalent material: AFNOR Z8CND17-04, ISO X4CrNiMo16-5-1, NS 14240, SS 2387, DIN X4CrNiMo16-5, EN X4CrNiCuNb16-5-1, ISO 4418-431-77-E, ISO MM17A, DIN 1.4418, DIN X4CrNiMo16-5-1, AFNOR Z6CND16-05-01, EN 1.4418
