Cpm Cruwear Vs M390: The Battle Of Powder Metallurgy Steels!?

The battle between CPM Cruwear and M390 powder metallurgy steels is one that has been hotly debated amongst knife enthusiasts for some time. Both steels are considered to be some of the best on the market, and each has its own unique properties that make it a desirable choice for different applications. In this article, we’ll be taking a closer look at each of these steels to determine which one is the superior option. We’ll be comparing their edge retention, corrosion resistance, ease of sharpening, and other properties in order to determine the winner in this battle of powder metallurgy steels.

Overview of cpm cruwear and m390 steel

CPM Cruwear and M390 are two of the most popular and widely used powder metallurgy steels on the market. Both steels are produced using a specialized production process called powder metallurgy. This process involves blending small particles of different types of materials together to form a homogeneous metal powder. The powder is then heated and pressed to form a solid steel bar.

CPM Cruwear is a high-end steel that is produced by Crucible Industries. It is made using a combination of high-carbon and alloyed steels. The steel is made to have excellent wear resistance and a high Rockwell hardness. This makes it ideal for making cutting tools, pocket knives, and other applications that require a hard and durable steel.

M390 is also a high-end steel that is produced by Bohler-Uddeholm. It is made from a combination of chromium, molybdenum, and vanadium. M390 is known for its superior corrosion resistance and wear resistance. This makes it suitable for applications that require a steel that is able to stand up to harsh environments and wear and tear over time.

When comparing the two steels, CPM Cruwear is generally considered to be the superior choice. It has a higher Rockwell hardness, making it the ideal choice for applications that require a hard and durable steel that can stand up to wear and tear. M390, on the other hand, is better suited for applications that require superior corrosion resistance, such as those found in marine environments.

Both CPM Cruwear and M390 are excellent choices for applications that require a high-end steel. While CPM Cruwear offers excellent wear resistance and a high Rockwell hardness, M390 has superior corrosion resistance and is better suited for applications that require a steel that can stand up to harsh environments. Depending on the application, either steel can provide the performance needed to get the job done.

Composition and properties of cpm cruwear and m390 steel

CPM Cruwear and M390 are two very popular powder metallurgy steels used in the production of knives and other cutting tools. Both are excellent for use in applications requiring a balance of edge retention and corrosion resistance. CPM Cruwear is a high-speed tool steel produced by Crucible Industries, while M390 is a stainless steel produced by Bohler-Uddeholm.

CPM Cruwear is a high-carbon, high-alloy steel made with the Crucible Particle Metallurgy (CPM) process. It is high in chromium, vanadium, and molybdenum, which gives it excellent wear resistance and edge retention. It also has a high hardness of 62-64 HRC, making it an ideal choice for cutting tools. CPM Cruwear is also corrosion resistant and can be used at high temperatures.

M390 is a high-alloy stainless steel made with the powder metallurgy process. It has a high chromium content of 20%, which gives it extreme corrosion resistance. In addition to this, it has high amounts of molybdenum and vanadium, which give it excellent wear resistance and edge retention. M390 is also heat treatable and can reach up to a hardness of 62-64 HRC, making it suitable for use in applications requiring a superior cutting edge.

So how do these two powder metallurgy steels compare? Both CPM Cruwear and M390 are extremely durable and corrosion resistant and have a high hardness of 62-64 HRC. CPM Cruwear has slightly better wear resistance and edge retention, while M390 has superior corrosion resistance. Ultimately, both steels provide excellent performance for cutting tools and knives, making them difficult to distinguish between.

Heat treating processes for cpm cruwear and m390 steel

The comparison between CPM Cruwear and M390 steel extends beyond just their properties and performance. It also extends to their heat treating processes. Both steels have distinct heat treating processes that are tailored to the particular properties of each steel.

The primary heat treating process for CPM Cruwear is cryogenic treatment. Cryogenic treatment involves subjecting the steel to temperatures below -150°C, usually -196°C. This process helps to increase wear resistance, toughness, and edge holding abilities. It also helps to reduce the likelihood of micro-cracking or warping due to the extreme temperatures. The cryogenic treatment also increases the corrosion resistance of the steel, making it more resistant to rusting or pitting.

For M390 steel, the primary heat treating process is double tempering. Double tempering involves heating the steel to temperatures ranging between 750-850°C for two separate tempering processes. This process helps to enhance the strength and wear resistance of the steel while also improving its corrosion resistance. The double tempering process also helps to increase the toughness of the steel, making it more resistant to chipping or breaking.

Cost analysis of cpm cruwear and m390 steel

Cost analysis of cpm cruwear and m390 steel

CPM Cruwear and M390 steel are two of the most popular powder metallurgy steels used in the knife industry. Though both steels offer exceptional performance and wear resistance, they can be quite expensive to purchase. Cost can be a deciding factor when choosing one of these steels, so a cost analysis is important.

CPM Cruwear is an American-made steel that is made by Crucible Industries and is a modified version of A2 tool steel. It is made through a powder metallurgy process using the Crucible Particle Metallurgy (CPM) process. CPM Cruwear offers excellent wear resistance and toughness, making it a great choice for knives. However, it is also one of the most expensive steels, with prices ranging from $6-20 per pound.

M390 is a German-made steel that is made by Bohler-Uddeholm and is a modified version of D2 tool steel. It is made through a powder metallurgy process using the Böhler-Uddeholm (BU) process. M390 offers excellent wear resistance, corrosion resistance, and edge retention, making it an excellent choice for knives. Its cost is slightly lower than CPM Cruwear, ranging from $4-15 per pound.

When it comes to cost, both CPM Cruwear and M390 are expensive, but M390 is slightly more affordable. However, the decision of which steel to purchase should not be based solely on cost, as both steels offer excellent performance and wear resistance. The performance of each steel should be taken into consideration when making a purchase decision.

Manufacturing considerations for cpm cruwear and m390 steel

The manufacturing considerations for CPM Cruwear and M390 steel are paramount when selecting the right steel for any given project. CPM Cruwear is a high-end powder metallurgy steel manufactured by Crucible Industries. It is a very hard steel with a very fine grain structure and excellent corrosion resistance. M390, on the other hand, is a powder metallurgy stainless steel manufactured by Bohler-Uddeholm. It is also a very hard steel but has a coarser grain structure and excellent edge retention.

The manufacturing process for both steels is very different. CPM Cruwear is made using a process called Crucible Particle Metallurgy (CPM). This is a process where the steel is heated up and then pressed into a mold. The particles of steel are very small and uniform, which makes it easier for the steel to be shaped and manipulated. This method also allows for a very fine grain structure.

M390, however, is made using a process called Vacuum Arc Remelting (VAR). This is a process where the steel is heated up and then melted in a vacuum chamber. This ensures that the steel is very uniform and can be manipulated into any shape desired. However, because of this process, the grain structure of M390 is much coarser than that of CPM Cruwear.

When selecting the right steel for any particular project, it is important to consider the manufacturing process used to make the steel. The manufacturing process of CPM Cruwear is ideal for projects where a very fine and uniform grain structure is desired, while the VAR process of M390 is ideal for projects where a very durable edge is desired. Ultimately, the decision of which steel to use should be made based on the project’s specific needs.
