What is M2 high speed steel?
M-2 High Speed Steel M-2 is a tungsten-molybdenum high-speed steel. It is a popular grade for cutting and non-cutting applications. Compared to M1 Tool Steel, M2 grade has a high carbon content which provides higher wear resistance for applications that need it.
Is M2 the same as HSS?
Molybdenum High Speed Steels (HSS) Combining molybdenum, tungsten and chromium steel creates several alloys commonly called “HSS”, measuring 63–65 Rockwell “C” hardness. M2 is the “standard” and most widely used industrial HSS.
What is high speed tool steel?
High speed tool steel comprises a set of tool steel alloys named for their capacity to cut materials faster than traditional high-carbon steels previously used in cutting tools.
How hard is M2 tool steel?
The mechanical properties of M2 molybdenum high speed tool steel are tabulated below….Mechanical Properties.
| Mechanical properties | Metric | Imperial |
|---|---|---|
| Hardness, Rockwell C (as hardened, quenched at 2200°F) | 65 | 65 |
Can you machine M2 steel?
M2 is classified as a “medium” machinability tool steel in the annealed condition. Its machinability rating is 50% as compared to the W group water hardening tool steels which are relatively easily machined.
What is the difference between M2 and M4 tool steel?
When present in significant amounts, vanadium carbides tend to dominate other types in affecting wear properties. For instance, M4 high speed steel’s chemical content is nearly identical to M2 high speed steel, except M4 contains 4% vanadium instead of 2%.
What is M2 tool steel used for?
M2 High Speed Steel. Our M2 steel is a general purpose molybdenum-type high-speed steel exhibiting well-balanced toughness, wear-resistance and red hardness properties. This grade is commonly used in cold work punches and dies and cutting applications involving high-speed and light cuts.
What grade is high speed steel?
The lowest alloy grades, M50 and M52 high-speed steels, are properly known as intermediate high-speed steels because of their lower alloy contents. The cobalt-bearing grades, such as M35 and M42, are known as super high-speed steels because they exhibit enhanced hot hardness.
What is the difference between tool steel and high speed steel?
Tool steel refers to a variety of carbon and alloy steels that are particularly when used for cutting and drilling. High Speed Steel is a high carbon tool steel, containing lots of tungsten and cobalt and is rich in molybdenum, tungsten and vanadium.
How hard is D2 tool steel before heat treat?
It is heat treatable and will offer a hardness in the range 55-62 HRC, and is machinable in the annealed condition. D2 steel shows little distortion on correct hardening.
Is high speed steel harder than tool steel?
High-speed steels exhibit high strength and hardness, but typically exhibit lower toughness than the cold work tool steels. The cobalt-bearing grades, such as M35 and M42, are known as super high-speed steels because they exhibit enhanced hot hardness.
What is m2 high speed steel?
The term high-speed steel comes from the ability of M2 to withstand higher temperatures without losing hardness. Therefore, it can stand up to the heat built up when higher machining speeds are used. Other terms used to describe M2 Steel are M2 HS (for High Speed) or M2 HSS (for High Speed Steel).
High-Speed Tool Steels High Speed Steels are a high-performance subset of tool steels, that are able to machine materials at high cutting speeds, thus the name High Speed Steel. This subset of tool steels is characterized high hardness (above 60 Rockwell C) and high wear resistance.
What is M4 high speed steel used for?
M4 is a molybdenum-tungsten high speed steel that is characterized by its high abrasion, wear resistance, transverse bend strength, and impact toughness. This specialty high speed steel was developed to have a greater abrasion and wear resistance for high tool life quality and cutting speeds.
What is AISI M2 steel?
AISI M2 Tool Steel is molybdenum based high-speed steel in tungsten–molybdenum series. HSS grade steel M2 is a medium alloyed high speed steel which has good machinability. The H-SS M2 chemical composition gives a good combination of well-balanced toughness, wear resistance and red hardness properties.
