T10 Steel Katana

T10 Steel Katana


T10 steel Katanas are classified among the finest and yet the most expensive Samurai Swords. They have probably went through the traditional processes of forging, heat treatment, water or oil quenching, clay tempering, yet they have particular properties that the others swords do not have. If they all are processed perhaps the same ways, some important differences are recorded between the several Katanas types, definitely inherited form the steel material they are made of. T10 Steel or equally called High Speed Steel is a material that excels the Steel material commonly used to make samurai swords. Therefore, T10 Steel Katanas are more appreciated than swords made of others Steel types. What are the characteristics of T10 Steel Katanas, and does the T10 Steel material require particular processes to be forged into piece of arts?

T10 Steel properties:

T10 steel, also known by Tool Steel or High Speed Steel is the Chinese designation for an alloy made of Carbon steel and Tungsten (W1 in the United States of America). The alloy contains a high tenor of Carbon compared to others Carbon Steels (about %1) and a little fraction of silicon (%0.35). The Tungsten component makes this type of steel very resistant to scratches and extremely tough. The maximum of resistance and toughness is obtained when properly tempered.

T10 Steel Katana Characteristics

T10 Steel Katanas share the characteristics of Carbon steel Katanas and Spring Steel Katanas. Yet, the tungsten element gives them the hardness and the extreme resistance to abrasion, which makes them the most resistant Katanas ever. Properly tempered High Speed Steel Katanas are very tough. The Clay tempering process and the differential solidity acquired after that process allows the Swords made of T10 steel to rank at the top of the list of durability. It appears that they should be the most expensive pieces, because of the required accuracy while forging the swords and the delicate operation to conduct to obtain the final thing. T10 Steel Katanas keep their edges as sharp as their first time for long period. Therefore they do not require extensive care and rigorous maintenance, they just need to be cleaned and properly kept. The proper use of these swords increases the durability.


Forging a T10 Steel Katana


Katana Sword

T10 Steel is a particular material. It is an Tungsten alloy that contains a high concentration of carbon and a little concentration of Silicon. To forge the High Speed Steel, It is necessary to preheat the alloy until it reaches 1100 F (593 C°), then increase the temperature to 1500 F ( 815 C°). The heating process is to operate slowly not to lose any amount of carbon. It is important to keep that the material at this temperature for about 30minutes then quench in water. Forging process is only possible and efficient at temperature starting from 815 C°. At inferior temperatures, the result would be deceiving and the material will be very resistant to the process and it will be very hard to manipulate. Tempering process can be operated at 343 C°.

The result of the appropriate treatment during forging process is obviously a very resistant and very hard Katana. The differential tempering, which consists in clay coating of the blade before polishing, with non-uniform distribution of clay layer thickness between edge and spine, allows the edge to be hard and the spine to be soft increasing the durability of the T10 Steel Katana.

T10 Steel Katana v.s. others swords

T10 Steel Katanas share several properties of 1095 carbon steel Katanas, but it is hardened by the Tungsten alloying element. Compared to the 9260 Female Warrior with her Katana swordSpring Steel katana which produces more suitable weapons when it is mono tempered, the T10 Steel Katanas are better hen Differentially Clay tempered. T10 Steel material allows the Katana to be very hard and increase its durability. Compared to Carbon Steel 1060 Katana, T10 Steel Katana tends to break instead of naturally bending -when being forged or used- but the edge will last longer. This material inherits the properties of same steels with same amount of carbon but acquires the properties of the Tungsten alloy which are durability, hardness and resistance to shock and abrasion. The Swords made of this material are therefore more expensive and may require high proficiency level to obtain the best results with the minimum risk of loss of material properties. It seems that the material properties imply the forging processes that allow the maximum results. Spring Steel Katana rank in the first place regarding the tensile power and the resistance to bending efforts, but the durability is compromised. The resistances to corrosion and oxidation are somehow the results of the alloy nature and type.



How to chose parts of the T10 Steel Katana

T10 Katana has a very tough blade which is very resistant to shocks; if it is intended to be used in training or shows, it is recommended that it is designed to be a full tang to sustain it. The handle should be made of resistant material not to be broken by the repetitive shocks. The guards would be resistant to deformation. the T10 Steel Katana blade.is one of the finest choice.

The overall cost of making and mounting a T10 Steel Katana is relatively high because of the straight rules to apply when forging the blade and the constraints that may apply while choosing the parts to add to the sword. The durability and the hardness of the material are very important factors that may increase the price of the final product.
