41CrAlMo7 38CrMoAl Double Screw Segments For Co-Rotating Twin Screw Extruders
Product Overview
41CrAlMo7 and 38CrMoAl are high-quality professional nitriding alloy steels, specially developed for heavy-duty twin screw extrusion equipment. These co-rotating screw segments undergo integral quenching, tempering and deep gas nitriding treatment, forming a dense and hard surface nitride layer. Compared with ordinary steel parts, they deliver higher surface hardness, better fatigue resistance and stronger anti-corrosion performance. With precise CNC machining and standard meshing clearance design, the screw segments realize efficient material plasticization and stable extrusion, effectively reducing material residue and equipment failure rate, perfectly adapting to various complex industrial extrusion scenarios.
