Corrodur 4418 Mod
Super 13Cr, UNS S41426
Description
Corrodur 4418 Mod exceeds the resistance of standard 13% chrome steel grades such as 1.4006 (AISI 410) and 1.4021 (AISI 420) and is therefore the first choice.

Corrosion properties
No hint on intergranular corrosion acc. to ASTM A 262 Prac. A (left) and Prac. E (right). The Oxalic Acid Etch Test carried out acc. for Prac. A showed no step, ditch or dual structure. Material for Prac. E was sensitized at 675 °C, kept in boiling, acidified CuSO4 for 15 h and then bent to 180°. No cracks were visible on the bent area.
