JSC EN-41B Barrels for MOLDING, EXTRUDER

Nitride Barrels Nitride Alloy Steel as base materials in all Plastics industry, We are using EN-41b MUSCO Material For all standard barrels. Thickness from 0.5 to 0.7 mm, hardness 65-68 HRC, Principle of nitride process is based on penetration of atomic nitrogen into the peripheral steel layer with the temperature of 550 C and it causes increasing the peripheral toughness by formation of nitrites and by depositing the nitride atom in areas between grids which causes grid tension Nitriding is a heat-treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface.
