Acciaio ad alta velocità ASTM T2 (UNS T12002)

ASTM/AISI T2 high speed steel is a Tungsten High Speed Steel grade Tool Steel in specification of ASTM A600. ASTM A600 standard covers tungsten-type and molybdenum-type high-speed steels used primarily in the fabrication of tools. There are seven types of tungsten high-speed tool steels designated T1, T2, T4, T5, T6, T8 and T15 etc.

AISI T2 high speed steel is an air-hardening medium alloy tool steel that has wear resistance intermediate between the high carbon chromium tool steels and oil hardening tool steels. But it offers good toughness and exhibits minimal distortion on hardening.
