Why Steel Type Is Important The second facet of the samurai sword an individual would probably need to check through is the type of metal used in the blade. Metals found in katana vary extensively, and each type of material has distinctive qualities that convey unique attributes on the sharp edge. These variations in the caliber and make of the material have a significant impact on katana effectiveness and resilience, modifying everything from the weight of the edge to the blade’s ability to maintain a sharp edge.
Carbon Steel The particular kind of metal frequently used is carbon metal. Carbon steels may vary in hardness by approximately HRC 50-60, depending on the carbon and chromium content of the edge. Some typical carbon metal grades you’ll find while purchasing a katana are 1020, 1040, 1060, and 1095. The higher the number, the more carbon utilized (roughly 0.2% - 1.0%), the firmer the sharp edge is. The greater the carbon in the blade, the higher level of resistance the sharp edge has to dulling and bending, making the sharp edge more dependable in general. Having said that, bear in mind that in the event the steel is harder, the edge also becomes significantly less impact-resistant and less soft, producing a samurai sword that is difficult to sharpen and cracks quicker. L6 Tool Steel and Martensite If a person is ready to invest more than a thousand bucks on a samurai sword, an individual might wish to consider a tough, heavy duty metal such as L6. L6 is a tool alloy of amazing robustness; fundamentally, it’s the material a person will see in high production industrial saws and jackhammers. Several samurai katana manufacturers have production blades created from L6. It’s good to be aware of martensite and bainite components in the katana; these crystalline structures appear in alloy as a consequence of very careful forging processes and tend to be exceptionally rough and tough, making for a trustworthy samurai katana. Spring Steel (AKA Carbon Steel Part 2) Sometimes, one will find katana which are created using spring steel. In truth, this is another name for carbon alloy, although several samurai katana suppliers make use of the term spring steel to indicate some types of metal with increased chromium content in the alloy (similar to the material used in vehicle springs). A sort of this metal I’ve seen quite often is used in a few Paul Chen Hanwei samurai katana, specifically in their cutting-edge series. They utilize 5160 high carbon spring metal in a few of their modern katana lines, generating cutting blades which are typically more impact resistant and durable than their 1060 counterparts. 5160 carbon alloy swords is often reliable; however, this alloy is not often employed in conventional Japanese samurai katana. As a result, both the shine of the cutting blade and the excellence of the hamon look very unusual in these swords.
Stainless Steel (Best Left In Cookware) The most common selection of metal noticed in lower level blades is 400, 420 or 440 stainless material which usually have a high chromium content and lower carbon content. Such swords are often sleek and frequently maintain excellent design quality, but stainless metal katana crack easily from usage and were not made for any type of reliable usage. The substantial chromium content of stainless metal makes the cutting blade break readily, which is not a really valuable trait in a dependable samurai sword.
