What is CPM M4 steel?

What is CPM M4 steel?

Description. CPM M4 is a high vanadium special purpose high-speed steel exhibiting better wear resistance and toughness than M2 or M3 in cold work punches, die inserts and cutting applications, but these reasons are why it is widely used in competition cutting blades.

Is CPM M4 steel stainless?

CPM M4 steel is not stainless steel because of its low chromium composition, making it prone to corrosion and rusting.

What is M4 steel used for?

M4 is an extremely versatile high-speed steel with its extremely high carbon and vanadium contents for exceptional abrasion-resistance. It is well suited for premium cutting tools of all types, particularly those used for machining abrasive alloys, castings and heat-treated materials.

What is the difference between M2 and M4 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 does CPM m4 stand for?

Crucible Particle Metallurgy
CPM stands for Crucible Particle Metallurgy and is a method of producing higher alloyed grades of superior quality than could be accomplished through conventional steelmaking. CPM steel is useful for high-alloy tool steel and high speed steel.

What is Rex 121 steel?

CPM REX 121 is a new high vanadium cobalt bearing tool steel designed to offer a combination of the highest wear resistance, attainable hardness, and red hardness available in a high speed steel. Its superior red hardness permits higher cutting speeds compared to other high speed steels.

What is Rex 45 steel?

CPM Rex 45 is a powder metallurgy version of the high speed steel M3:2 plus cobalt. This grade is relatively common in Europe, being produced as Erasteel ASP 2030, Uddeholm Vanadis 30, and Bohler S590. And Hitachi HAP40 in Japan.

What is CPM S35VN steel?

CPM S35VN is a martensitic stainless steel designed to offer improved toughness over CPM S30V. It is also easier to machine and polish than CPM S30V. Its chemistry has been rebalanced so that it forms some niobium carbides along with vanadium and chromium carbides.

What is Vanax steel?

Uddeholm Vanax SuperClean is the long-awaited response to the market’s need for steel that is both strong and stainless. Combining the corrosion resistance of austenitic stainless steel such as AISI 316L, with a hardness of 60 HRC and the wear resistance of a cold work tool steel, opens up new opportunities.

Is CPM Rex 45 a good steel?

CPM REX 45 is good knife steel because it offers excellent hardness, edge retention, and wear resistance for high-end performance. The addition of cobalt and tungsten in its alloy ensures that Rex 45 steel knives are extremely hard and incredibly resistant to wear.

Is CPM M4 considered stainless steel?

Many people assume that CPM M4 is considered stainless steel. However, CPM M4 does not contain a high enough percentage of chromium to be considered stainless. Steels must have a minimum of 12% of chromium to be classified as stainless. CPM M4 is categorized as carbon steel due to its high percentage of carbon.

What is CPM Rex M4 steel?

What Is CPM REX M4?often called simply PM M4 steel, is a special-purpose type of high speed steel. It is noted for its wear-resistance characteristics.

What are the benefits of tempering CPM M4 steel?

Tempering can also help increase the ductility and hardness of the material, making it easier to machine. CPM M4 steel should be heated to a temperature below the critical point, maintaining hardness while also decreasing brittleness.

What is pm M4 high speed tool steel?

PM M4 high speed tool steel is a flexible steel that provides a unique combination of high wear-resistance with high impact toughness and bend strength, which are results of the fine grain size, small carbides and superior cleanliness of the steel. PM M4 offers improved cutting tool life compared to conventionally-wrought M1,…
