ASTM A600 specification covers tungsten-type and molybdenum-type high-speed steels available as annealed, hot-rolled bars, forgings, plate, sheet, or strip, and annealed,cold-finished bars or forgings used primarily in the fabrication of tools.
In ASTM A600 here are Seven types of tungsten high-speed tool steels designated T1, T2, etc., seventeen types of molybdenum high-speed tool steels designated M1, M2, M35, M42 etc., and two intermediate high speed steels designated as M50 and M52 are covered. Selection will depend upon design, service conditions, and mechanical properties.
High Speed Steel M2 | 1.3343 | HS-6-5-2C | SKH51
AISI M2 Tool Steel is molybdenum based high-speed steel in tungsten–molybdenum series. HSS steel grade M2 is a medium alloyed high speed steel which has good machinability.
ASTM High Speed T6 Tool Steel (UNS T12006)
ASTM T6 Tool Steel is one tungsten type high speed steel in ASTM A600 specification. Check the chemical composition, mechanical properties of T6 too steel.
ASTM T4 Tool Steel | 1.3255 | S 18-1-2-5 | SKH3
AISI T4 tool steel is one of tungsten type high speed tool steel, which belongs to ASTM A600. Other equivalent steel grades are DIN 1.3255 / S 18-1-2-5, JIS SKH3.
ASTM T2 High Speed Steel (UNS T12002)
ASTM/AISI T2 high speed steel is a Tungsten High Speed Steel grade Tool Steel in specification of ASTM A600. AISI T2 high speed steel is an air-hardening medium alloy tool steel.
T1 Tool Steel High Speed | 1.3355 | HS18-0-1 | SKH2
AISI/ASTM T1 tool steel is one of the original tungsten high speed steel. T1 high speed steel is an air or oil hardening tool steel which has good comprehensive performance.
High Speed Tool Steel M35 | 1.3243 | HS6-5-2-5 | SKH55
ASTM A600 tool steel M35 is a medium-alloyed high speed tool steel. It is also known as HSSE or HSS-E which is similar to M2, but with 5% cobalt added, which makes better hot hardness and wear resistance.
M42 Tool Steel High Speed | 1.3247 | HS2-9-1-8 | SKH59
AISI high speed steel material M42 tool steel is a molybdenum-series high-speed steel alloy with an additional 8% cobalt. High-speed steel M42 steel is widely used in metal manufacturing industries and in cutting tools manufacturing.
M2 Tool Steel | 1.3343 | HS-6-5-2C| SKH51
AISI M2 Tool Steel is molybdenum based high-speed steel in tungsten–molybdenum series. HSS steel grade M2 is a medium alloyed high speed steel which has good machinability.
