SG-PX 46 NiMo Rolls
SG-PX-Mo 46 Nodular Graphite iron hasa special behav ior due to its unique matrix.Composition of roll shows high ferrite nodules. The material provides properties associated with both traditional acicular and pearlitic qualities. Oval Graphite noduls are surrounded with ferrite, named as the “bull’s eyes” is the most important characteristic of the SG-PX-Mo 46 rolls. This quality is convenient for high temperature heat treat ed, high Mo alloyed,pearlitic or acicular nodular iron.
The microstructure ranges from pearlite in the lower alloyed grades to acicular phase in the higher alloyed and heat treated grades. The presence of bull’s eyes (spheroidized graphite surrounded by a layer of ferrite) provides strength, toughness and fire-cracking resistance. The high strength and thermal resistance of SG-P-Mo make it an suitable roll material for use in roughing applica tions where thermal duty is severe.
These rolls have high strength and excellent resist ance against fire-cracking, therefore making them very suitable for heavy duty applications and espe cially in slow rolling Roughing stands.
