CPM Magnacut steel and CPM CruWear are each powder metallurgy metal developed by Crucible Industries adhering to the Crucible Particle Metallurgy (CPM) procedure that effects in a homogeneous microstructure with a finer, additional uniform carbide distribution.
For the context of this write-up, I will be hunting at CPM CruWear which is a powder metallurgy model of the typical ingot CruWear metal.
MagnaCut was formulated by Dr. Larrin Thomas as a knife metal with a well balanced solution to characteristics like toughness, edge retention, and corrosion resistance.
CruWear on the other hand is a standard device metal with an method in the direction of higher toughness for its industrial apps in the producing of industrial knives, dies, and punches.
When equally CPM Cru-Don and CPM MagnaCut offer you superb edge retention and don resistance, MagnaCut stands out with its superior corrosion resistance. This is for the reason that MagnaCut is a stainless metal, even though Cru-Have on is a resource steel.
MagnaCut achieves extraordinary corrosion resistance by eliminating chromium carbides, enabling it to attain substantial hardness concentrations unmatched by other stainless steels. In distinction, Cru-Put on, with its coarse chromium carbides, is susceptible to rusting.
For people trying to find high-effectiveness stainless metal cutlery, MagnaCut’s balanced characteristics of hardness, edge retention, and corrosion resistance make it a prime choice above Cru-Put on.

Composition
Hardness
CPM MagnaCut and Cru-Put on exhibit some vital variances in hardness. In accordance to the Crucible Steel Facts Sheet, the utmost attainable hardness is marginally better for CPM Cru-Use as opposed to MagnaCut.
CPM MagnaCut has a normal Rockwell hardness selection of 60-64 HRC, with a advisable warmth treatment hardness of 60 HRC for an exceptional balance of attributes.
In comparison, CPM Cru-Put on can achieve a little bit larger hardness with a selection of 60-65 HRC. Cru-Wear advised warmth cure hardness of 62 HRC, which is 1-2 details better than that of CPM MagnaCut.
MagnaCut vs M4 steel
Edge Retention
CPM MagnaCut and CRU-Dress in are incredibly closely matched in edge retention and reducing means. Both steels are capable of attaining superior hardness amounts in the 60-64 HRC range when effectively warmth addressed.
This large hardness will come from steady vanadium-prosperous carbides that resist abrasive wear and aid the steels hold an edge well.
On the other hand, MagnaCut options the two vanadium and niobium carbides, which can supply extra perfectly-rounded wear resistance and edge security.
My real-world testing signifies that knives designed from both Magnacut or CruWear metal show great edge retention and can just take and hold an incredibly high-quality edge when sharpened.
Toughness
Although CPM MagnaCut is renowned for its outstanding toughness, CPM CruWear can be thought of to have a bit far better toughness than CPM MagnaCut metal. The larger toughness of Cru-Wear steel is attributed to the reduced volume of pretty great and evenly dispersed carbides.
MagnaCut on the other hand has a little bit better volume of carbides which are fantastic for other houses like have on resistance but are considered brittle and that’s a bit lowering the toughness of the steel.
In my use, I discovered incredibly minimal toughness change involving knives built from either steel although it’s worthy of pointing out that CPM CruWear has remarkable toughness main MagnaCut steel.
Corrosion Resistance
MagnaCut steel has greater corrosion resistance than CPM CruWear steel, this is simply because MagnaCut is a stainless steel though Cru-Put on is a non-stainless metal.
In my unbiased screening, the corrosion resistance of Magnacut outperformed CruWear as it was in a position to face up to salty h2o droplets right away with no rusting forming on the surface area when CruWear extensively formed rust on the area.
MagnaCut achieves excellent corrosion resistance by uniquely eradicating chromium carbides in its matrix. By removing these Chromium Carbides, Magnacut is also capable to realize a bigger Rockwell hardness amount than other stainless steels.
This exclusive blend of large hardness and corrosion resistance is only current in a handful of stainless steels like Crucible S110V steel and is even greater than the well-liked M390 Steel
Simplicity of Sharpening
CPM MagnaCut gives significantly superior relieve of sharpening compared to CPM CruWear. MagnaCut’s incredibly fine microstructure, ensuing from state-of-the-art powder metallurgy manufacturing, permits a great deal less complicated grinding, finishing, and sharpening than anticipated for its hardness degree and alloy material.
The fine carbides resist abrasion properly all through sharpening, deburr easily, and get a keen edge that is extremely responsive to stropping. In contrast, CPM CruWear has coarse chromium-wealthy carbides that hinder abrasion in the course of grinding and sharpening.
I observed that the MagnaCut knife sharpens less difficult than CruWear, and even sharpens much better than CPM-154 knives.
For each knife lovers and hobbyists trying to find to optimize the sharpenability of higher-overall performance instrument steel cutlery, MagnaCut represents a apparent action ahead in ease of sharpening as opposed to CPM CruWear and other carbide-rich alloys.
Pricing
Irrespective of MagnaCut blade steel giving a balanced strategy to its features in comparison to CPM CruWear blade steel.
Magnacut knives tend to be a tiny little bit more affordable than CPM CruWear knives, most Magnacut knives variety between USD 150 to USD 200 though CPM CruWear are a little bit extra highly-priced ranging from USD 200 upwards as of Jan 2024.
Pricing and availability may adjust more than time as MagnaCut knife metal gains much more level of popularity.
Summary Magnacut vs Cruwear
In conclusion, CPM MagnaCut and CPM Cru-Use steel show dissimilarities in hardness, with Cru-Wear possessing a a little bigger utmost attainable hardness.
Both steels display comparable edge retention, but MagnaCut’s inclusion of niobium carbides supplies supplemental wear resistance and edge steadiness.
Whilst MagnaCut is known for exceptional toughness, Cru-Dress in is considered somewhat tougher owing to the lower volume of fine and evenly distributed carbides.
MagnaCut surpasses Cru-Use in corrosion resistance, attributed to its stainless metal character. MagnaCut also outshines Cru-Use in ease of sharpening, thanks to its high-quality microstructure from superior powder metallurgy.
Astonishingly inspite of MagnaCut metal knives presenting a additional well balanced profile, they are likely to be priced lessen than CPM Cru-Put on knives, generating MagnaCut a price-productive preference for all those looking for large effectiveness in their knives.
