Powdered steel for cold processing tool

Powdered steel for cold processing tool

Disclosed is a powdered high speed tool having good wear resistance used for producing cold processing tools such as forging molds and rolling rollers. The powdered high speed tool steel essentially consists of 1.5 - 5.0 % of C, up to 3.0 % of Si, up to 3.0 % of Mn 10 - 30 % of Cr, 0.5 - 4.0 % of Mo...

description Disclosed is a powdered high speed tool having good wear resistance used for producing cold processing tools such as forging molds and rolling rollers. The powdered high speed tool steel essentially consists of 1.5 - 5.0 % of C, up to 3.0 % of Si, up to 3.0 % of Mn 10 - 30 % of Cr, 0.5 - 4.0 % of Mo, 0.1 - 10 % of V and the balance substantially of Fe, provided that the followings are met: F(C) = Cr + 15.5C >/= 40, and F(H) = 3.8C - 0.62Cr >/= -5. The steel may optionally further contain up to 10 % of Mo in the range that W + 2Mo is up to 8.0 %.
