Product Description

Alloy cast steel roll for hot rolling mill
Description
Through different chemical composition and heat treatments, the work layer of cast steel rolls could be obtain pearlitic, sobitic, tempered sorbitic and bainitic matrix. With small granularity of carbides, the cast steel rolls possess better tensile strength and tenacity as well as excellent biting properties and thermal cracking resistance.
