Material Description

Material Number	Material Name	Material Number (single)	Standard	Scope	Standard Status	Country	VDA 231-106 classification	Application temperature [°C]
1.4767 (DIN 17470 : 1984-11)	CrAl 20 5	1.4767	DIN 17470 : 1984-11	Replacement for DIN 17470 : 1963-07 and DIN 59470 : 1963-07	Valid	Germany	1.1.2	≤ 1200	1)
1) Remark: Ferritic heat conductor material for applications up to 1200 °C in air. Medium resistance at 20 °C to atmospheric corrosion, high corrosion resistance to air and oxygen-containing gases, low corrosion resistance to nitrogen-containing gases, high corrosion resistance to sulfur-containing gases. Preferred application: high temperature furnaces, kilns
