Material Description

Material Number	Material Number (single)	Standard	Range of Application	Standard Status	Country	Predecessor	Remark	Application temperature [°C]
1.4550 (DIN EN 10217-7 : 2021-06)	1.4550	DIN EN 10217-7 : 2021-06	Supersedes DIN EN 10217-7 : 2015-01	Valid	Germany	X6CrNiNb18-10	The austenitic steel X6CrNiNb18-10 is available in the solution annealed condition. Welded circular tubes of this steel are used for compression load and for corrosive load at room temperature, low temperatures and elevated temperatures. The material is resistant to intercrystalline corrosion (up to 400 °C) also in the welded condition.	-10 - 400
