Material Notes:

AISI D2 is a high-carbon, high-chromium tool steel alloyed with molybdenum and vanadiumAISI AD2 is characterized by: High wear resistance High compressive strength Good through-hardening properties High stability in hardening Good resistance to tempering-backApplications: AISI D2 is recommended for tools requiring very high wear resistance, combined with moderate toughness (shock-resistance). AISI D2 can be supplied in various finishes, including the hot-rolled, pre-machined and fine machined condition.
