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.
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 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.
Is M4 steel stainless?
It can be hardened to around 62-64 HRC but note M4 is a carbon steel is not considered stainless with relatively low levels of chromium. So, while this is one of the best steels around for cutting, it has to be properly cared for and may develop a patina over time.
Is M4 a tool steel?
M4 is another in the Molybdenum High Speed Tool Steels. It has a relatively high 1.3% carbon content for high hardness and excellent wear resistance. Used for cutting tools of all types for machining operations.
Is CPM S35VN stainless?
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.
Is M4 steel corrosion resistant?
CPM M4 Tool Steel Chemical composition These are responsible for M4’s high toughness, excellent corrosion resistance, and wear resistance. 1.42% Carbon increases tensile strength, edge retention, and hardness. It also improves wear and corrosion resistance.
When was S35VN invented?
2009
S35VN, first created in 2009, modified the formula of S30V by adding niobium to the vanadium and chromium carbide forming elements.
Does CPM S35VN steel rust?
By taking a single look at the list, you can see that the chemical composition of S35VN steel is a combination of high Carbon, Vanadium, Chromium, and Molybdenum, which provides the steel with corrosion resistance, excellent wear resistance, and toughness.
