Alloy Cast Steel Rolls Grade 75I (AS75I) for Blooming and Slabbing Mills

Alloy Cast Steel Rolls 75I (AS75I) usually contain alloy elements, which improve their wear resistance and can withstand the friction and wear of the metal billet during high-speed rolling, extending the service life of the rolls. It can withstand large rolling pressure and impact load, ensuring the stability of the rolling process. The alloy elements of alloy cast steel rollers improve their corrosion resistance, making them suitable for rolling processes in some special environments. Alloy cast steel roll 75I has the advantages of wear resistance, high hardness, corrosion resistance, cost-effectiveness, etc. It is suitable for rolling equipment such as blooming mills and plate-cutting machines. It is a commonly used roll material with good performance.
