Extrusion Screws

Screw from Dia. 25 mm to 200 mm & Length upto 6000mm

BASE MATERIAL: Screws are made from nitroalloy steel (AISI 4340 NITRALLOY 135M), stainless steel (304, 316, 416, 17-4ph), Tool steel & CPM tool steel.

HARDENING & HEAT TREATMENT: Toughening, Tempering, Gas/Ion Nitriding& Additional Bimetallic Coatings can be incorporated. We also do special surface treatment like hard nickel plating, chrome plating & PVD coatings, HVOF Thermalspray & PTA weld overlay, vacuum through hardend screws.
