What is M2 HSS steel?

What is M2 HSS 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.

How hard is M2 tool steel?

The mechanical properties of M2 molybdenum high speed tool steel are tabulated below….Mechanical Properties.

What is M2 steel used for?

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 is SKH51 material?

JIS SKH51 tool steel have good hot-hardness and high quenching hardness. Its others name have Wind steel or Sharp steel, mean even quenching cooling in air can be hardened, and very sharp. Normal use in Tool, Forging industry, Screw industry, etc.

What is the difference between M2 and M42 steel?

M42 is less prone to chipping or breakage than conventional M2 on tougher applications. Rockwell “C” scale hardness for M2 is 61 to 64; M42 is up to 68. M42 is much harder to machine than M2. M42 differs from M2 in the following general chemical analysis.

What is the toughest tool steel?

The hardest and therefore the most abrasion resistant carbides typically found in tool steels are the vanadium carbides.

What is difference between M1 and M2 steel?

M2 is a higher carbon version of the M1 tool steel (Molybdenum High Speed Tool Steel). The M2 alloy has somewhat better wear resistance than M1. Primarily used for cutting tools. M2 is classified as a “medium” machinability tool steel in the annealed condition.

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 M35 steel?

ASTM A600 M35 steel 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.

What is the best high speed steel?

PM T15. This high speed tool steel shares the qualities of high wear resistance and impact toughness with M42 steel but is unique in that it has superior bend strength. This purple hardness, cobalt series steel grade is formed from clean steel with fine grain and small carbides.

Which tool steel is best?

Air Hardening (A-Grades) This is a very versatile, all-purpose tool steel that is characterized by low distortion factor during heat treatment, due to the increased chromium content. This tool steel has good machinability and a balance of wear resistance and toughness.

What grade is tool steel?

Tool Steel Grades and Corresponding Applications The AISI-SAE general purpose grades of tool steel are O-1, A-2, and D-2. These standard grade steels are considered “cold-working steels,” that can hold their cutting edge at temperatures up to about 400°C.

What does the D in D2 steel mean?

The D-series of the cold-work class of tool steels are considered high Carbon-Chromium Steels. D2 steel is air hardened and contains between 10% and 13% chromium (which is unusually high). D2 steel has a hardness in the range of 55 to 62 HRC, which makes is a very durable and high- end knife steel.

What is P2 material?

Introduction. Low-carbon mold steels or group P steels comprise different types that include P2, P3, P4, P5, P6, P20, and P21 steels. Chromium and nickel are the main alloying elements found in group P steels. P2 tool steels are carburizing steels manufactured according to tool steel quality standards.

What is the hardness of HSS?

Combining molybdenum, tungsten and chromium steel creates several alloys commonly called “HSS”, measuring 63–65 Rockwell “C” hardness.
