High Speed Tool Steel Products: M2 - M4 - M42 - T1 - T15

T15 is a tungsten type super high speed steel that contains vanadium and cobalt. The high content of vanadium provides excellent abrasion and wear resistance. The cobalt content in this grade provides very high resistance to softening at high service temperatures (red-hardness). T15 high speed steel can be heat treated as high as 67 HRC.

Cobalt - Wikipedia

Cobalt is primarily used in lithium-ion batteries, and in the manufacture of magnetic, wear-resistant and high-strength alloys. The compounds cobalt silicate and cobalt(II) aluminate (CoAl 2 O 4, cobalt blue) give a distinctive deep blue color to glass, ceramics, inks, paints and varnishes. Cobalt occurs naturally as only one stable isotope ...
