ASTM A600-92a(2016)

Standard Specification for Tool Steel High Speed

ABSTRACT
This specification covers seven tungsten-type (types T1, T2, T4, T5, T6, T8, and T15) and nineteen molybdenum-type high-speed steels (types M1, M2, M3, M4, M6, M7, M10, M30, M33, M34, M36, M41, M42, M43, M44, M46, M47, M48, and M62) in the form of annealed, hot-rolled bars, forgings, plate, sheet, or strip, and annealed, cold-finished bars or forgings used primarily in the fabrication of tools. Two intermediate high speed tool steels designated as M50 and M52 are also covered. Unless otherwise specified, material shall be made by an electric melting process. A chemical analysis of each heat of steel shall be made to determine the percentage of the elements specified (including carbon, manganese, phosphorus, sulfur, silicon, chromium, vanadium, tungsten, molybdenum, and cobalt) and these values shall conform to the requirements as to the prescribed chemical composition. Requirements for: (1) heat treatment such as austenitizing, quenching, and tempering, (2) hardness testing (3) macrostructure and macroetch standard for porosity and ingot pattern, and (4) decarburization determination are detailed. The maximum Brinell hardness and minimum Rockwell C hardness for the tool steels are given.
SCOPE
1.1 This 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.  
1.2 Seven types of tungsten high-speed tool steels designated T1, T2, etc., seventeen types of molybdenum high-speed tool steels designated M1, M2, etc., and two intermediate high speed steels designated as M50 and M52 are covered. Selection will depend upon design, service conditions, and mechanical properties.  
1.3 The term “high-speed steel” is described and its minimum requirements are covered in the Annex.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Standard Specification for
Tool Steel High Speed
This standard is issued under the fixed designation A600; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope
1.1 This 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.
1.2 Seven types of tungsten high-speed tool steels designated T1, T2, etc., seventeen types of molybdenum high-speed tool
steels designated M1, M2, etc., and two intermediate high speed steels designated as M50 and M52 are covered. Selection will
depend upon design, service conditions, and mechanical properties.
1.3 The term “high-speed steel” is described and its minimum requirements are covered in the Annex.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.

3. Classification
3.1 Material in accordance with this specification is classified by chemical composition. Types correspond to respective AISI
designations.
3.1.1 Types T1, T2, T4, T5, T6, T8, and T15 are characterized by a controlled high tungsten content along with other alloying
elements.
3.1.2 Types M1, M2, M3, M4, M6, M7, M10, M30, M33, M34, M36, M41, M42, M43, M44, M46, M47, M48, and M62 are
characterized by a controlled high molybdenum content along with other alloying elements.
This specification is under the jurisdiction of ASTM Committee A01 on Steel, Stainless Steel and Related Alloys and is the direct responsibility of Subcommittee A01.29
on Tool Steels.

3.1.3 Types M2, M3, and M10 are further classified according to carbon range. Type M3 is further classified according to
vanadium range.
3.1.4 Types M50 and M52 are considered intermediate high speed steels in view of their lower total alloy content than the
standard types. These leaner alloy grades normally are limited to less severe service conditions.

4.1.3 Shape (sheet, strip, plate, flat bar, round bar, square bar, hexagon bar, octagon, special shapes),
4.1.4 Dimensions (thickness, width, diameter, length). (For coils, include the minimum inside diameter or inside diameter range,
the maximum outside diameter, and maximum or minimum coil weight if required. (Minimum coil weights are subject to
negotiation.)),
4.1.5 Finish (hot rolled, forged, blasted or pickled, cold drawn, rough machined, ground, precision ground and polished),
4.1.6 Condition (annealed),
4.1.7 ASTM designation and date of issue, and
4.1.8 Special or supplementary requirements.
5. Materials and Manufacture
5.1 Unless otherwise specified, material covered by this specification shall be made by an electric melting process.
6. Chemical Composition
6.1 An analysis of each heat of steel shall be made by the manufacturer to determine the percentage of the elements specified
and these values shall conform to the requirements as to chemical composition specified in Table 1. If requested or required, the
chemical composition shall be reported to the purchaser or his representative.
6.2 Analysis may be made by the purchaser from finished bars and forgings by machining off the entire cross section and drilling
parallel to the axis of the bar or forging at any point midway between the center and surface in accordance with the latest issue
of MethodPractice E59. The chemical analysis of the drilling chips shall be made in accordance with the latest issue of Test
Methods E30. The chemical composition thus determined shall not vary from the limits specified in Table 1.
7. Hardness Requirements
7.1 Annealed hardness values when obtained in accordance with the latest issue of Test Methods and Definitions A370 shall
not exceed the Brinell hardness values (or equivalent Rockwell hardness values) specified in Table 2.
7.2 Specimens for determination of minimum response to hardening shall be ⁄4-in. (6.4-mm) thick disks cut so as to represent
either the full cross-sectional area or that midway between the center and outer surface of the material. If the material form or size
does not lend itself to accurate hardness determination on ⁄4-in. thick cross-sectional disks, then longitudinal specimens may be
used for hardness testing. Examples are round bars less than ⁄2 in. (12.7 mm) in diameter; sheet; and strip. In this case, the
specimen shall be a minimum of 3 in. 3 in. (76.2 mm) in length, and parallel flats shall be ground on the original mill surfaces.
The specimens shall be heat treated in two furnaces, one operating as a preheat furnace and the other as a high-heat furnace. The
furnaces may be either controlled atmosphere or molten-salt bath. The austenitizing temperature ranges stipulated in Table 3 cover
both furnace types.
7.2.1 After being austenitized for the proper time, the samples may be oil quenched or quenched in molten salt plus air cooling.
When a salt quench is employed, its temperature shall be 1050 to 1175°F (566 to 635°C) except for M3, M4, M41, , M42,M43
, M42, M43, M46, M47, M48, M62, and T15, when it shall be 1000 to 1075°F (538 to 579°C). All samples shall be double
tempered at 1025°F (552°C) for 2 h each cycle except for M0 and M52 which shall be given two tempering cycles of 2 h each
at 1000°F and M41, M42, M43, M44, M46, M47, M48, M62, and T15, which shall be given three tempering cycles of 2 h each
at 1000°F.
7.2.2 The hardness of the specimen after the specified heat treatment shall meet the minimum hardness value for the particular
type of steel shown in Table 3. Rockwell C tests should be used where possible but light-load tests may be necessary on thin
specimens. These tests should be specified by agreement between seller and purchaser. The hardness value shall be obtained in
accordance with the latest issue of Test Methods and Definitions A370 and shall be the average of at least five readings taken in
an area midway between the center and surface of the largest dimension of the cross-sectional specimen or along the parallel
surfaces of the longitudinal specimen. The surface to be tested shall be ground sufficiently to remove any surface condition, scale,
carburization, or decarburization which might affect readings.
