Mill Roll Grade Selector
Pick your mill type and stand position — we map it to the material family and hardness band from the selection matrix, so you specify rather than guess.
Hardness scales (Shore/HS, HSD, HRC, HB) are different scales and are not directly interconvertible. Bands are typical industry ranges for the grade family, not fixed limits — confirm the exact grade and hardness against your stand schedule.
