High Speed-2

Color Code:
ORANGE WITH BLACK STRIPE

Ameralloy High Speed-2 is the most widely used type of high-speed steel. It is generally used for the same applications as T-1 high speed. Ameralloy High Speed-2 has higher carbon content and balanced analysis producing properties applicable to all general-purpose high speed uses.

Typical Analysis

  • Carbon .86
  • Chromium 4.15
  • Tungsten 6.35
  • Molybdenum 5.00
  • Vanadium 1.90

Applications

  • Lathe tools
  • Planer tools
  • Drills
  • Taps
  • Reamers
  • Broachers
  • Milling cutters
  • Form cutters
  • Wood knives
  • Gear cutters
  • End mills

Features And Advantages

  • Balanced abrasion and shock resistance
  • Good red-hardness
  • Weighs 6% less than T-1 high speed
  • Can be hardened at 100° below T-1 high speed

Characteristics

Machinability Like all highly alloyed steels, High Speed-2 machines with somewhat more difficulty than the lower alloyed steels. It is rated at 65 as compared to a 1% carbon tool steel, which is rated at 100.

Critical points Critical points obtained by dilatometer tests when heating at a rate of 400° per hour and cooling at 30° per hour are as follows:

Heating – Ac range 1530° to 1610°F


Cooling – Ar range 1430° to 1380°F

Heat Treatment

Forging 2050°–2100°F, stop at 1800°F and cool slowly

Annealing 1600°F, cool slowly. Brinell 241 max.

Preheating 1550°F, soak before hardening

Hardening 2250° to 2275°F, oil-quench

Tempering 1000°–1050°F, Rockwell C 65-66

Available Shapes And Sizes

  • Rounds
  • Squares
  • Flats

Standard lengths 10’–12’ or cut to specified length. Modified and special sizes available upon request. Prompt forging service available.
