CarTech M2 Steel

CarTech M2 Steel

Steel name: CarTech M2
Diagram No.: 2295
UNS designation: T11302
AISI/SAE designation: M2
Chemical composition in weight %: 0.82% C, 0.25% Si, 0.30% Mn, 4.25% Cr, 5.00% Mo, 1.80% V, 6.25% W
Steel group: High speed steels
Properties: CarTech M2 high speed steel is a fine grained molybdenum-tungsten high speed steel which possesses advantages over 18-4-1 high speed steels including less weight per cubic inch, lower hardening temperature and somewhat easier machining.
Applications: Lathe tools, planer tools, drills, taps, reamers, broaches, milling cutters, form cutters, thread chasers, end mills, gear cutters, wood knives.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: First, preheat to 1400/1500°F (760/816°C), then transfer to a superheating furnace with a temperature maintained at 2150/2250°F (1177/1232°C). When neutral salt baths are used for hardening, the temperature should be dropped 25°F (14°C) as compared to furnace temperatures.
Tempering: Be sure to allow sufficient time for the tool to reach the proper temperature and then start timing the tempering operation. Tools should be tempered immediately after the completion of the quench. For best results with most tools, a range of 1025/1050°F (552/566°C) should be used.
