※Material Indication： 

M2 is Cr12MoV of Chinese steel grade, D2 is W6Mo5Cr4V2 of Chinese steel grade.

“Ω” Alloy series is researched and developed by us specially for the oval liner of Twin Screw Extruder, at the request of German W&P company, to get high wear-resistance performance, respectively is a high chromium iron alloy and a high vanadium iron alloy.

 Oval Liner
