Introduction The world of knife making continually evolves as manufacturers innovate and harness new technology to perfect the functionality and durability of the blades they produce. One such development is the creation of the CPM REX 45 knife steel, a high-performance and reliable type of steel that has found increasing use in various applications. To appreciate the unique features of CPM REX 45, it is crucial to understand its composition and history. This article aims to provide an insightful evaluation of this remarkable knife steel that has been attracting attention within the knife-making industry. Metal Composition of CPM REX 45 In comparison to other types of steel used for knife blades, CPM REX 45 has a unique composition that sets it apart. It is important to note the percentages of various metals that form this steel: - Carbon: 1.30% - Chromium: 4.05% - Cobalt: 8.00% - Manganese: 0.30% - Molybdenum: 5.00% - Silicon: 0.50% - Sulfur: 0.06% - Tungsten: 6.25% - Vanadium: 3.05% The composition of CPM REX 45 yields certain desirable properties ideal for making knife blades. For instance, high levels of carbon improve the hardness and strength of the steel, while chromium content offers corrosion resistance. Cobalt, on the other hand, enhances the steel's heat-resistance and ability to sustain high-temperature performance. The presence of molybdenum and tungsten ensures outstanding wear resistance and cutting ability. History of CPM REX 45 Knife Steel The development of the CPM REX 45 knife steel traces its roots to Crucible Industries, one of the leading American companies specializing in the production of high-performance steel. Several decades ago, Crucible Industries began researching and developing various steel compositions that would result in superior blade quality for a wide range of applications. This research led to the inception of the CPM REX series, which involved experimenting with particle metallurgy to create a meticulous and uniform distribution of carbides within the steel. This process pushed the limits of steel performance and resulted in steel with enhanced cutting capabilities and wear resistance. CPM REX 45 is one of the more recent additions to the CPM REX series, showcasing the culmination of years of research and development. A high-speed tool steel, CPM REX 45 combines a perfect blend of characteristics designed to meet the requirements for challenging knife applications. Its popularity has grown, and the steel features in some renowned knives from brands like Spyderco and Benchmade. Conclusion: Why Choose CPM REX 45? CPM REX 45 knife steel boasts a range of properties that make it suitable for various knife applications. Its hardness, wear resistance, and corrosion resistance ensure its performance and longevity as a blade material. Add to that its unique history and innovation, which gives the steel a sense of distinction in the knife making industry. When considering a knife steel for your next exceptional blade, it would be prudent to explore the potential of CPM REX 45.
