CTS BD1 is a high-carbon, high-chromium stainless steel recognized for its well-balanced properties. The composition of CTS BD1 includes:
CTS BD1 achieves a Rockwell hardness of 58-60 HRC after proper heat treatment. This level of hardness is comparable to tool steels and ensures excellent edge retention and wear resistance. The combination of high carbon content and fine grain structure allows CTS BD1 to hold an edge well, reducing the frequency of sharpening required. This makes it an ideal choice for applications requiring a sharp, durable edge, such as in cutlery and precision tools.
The high chromium content in CTS BD1 provides excellent corrosion resistance, making it comparable to Type 410 stainless steel. This property makes CTS BD1 suitable for use in environments where exposure to moisture and mild corrosive elements is common. The steel’s resistance to rust and staining ensures longevity and reliability in various conditions.
CTS BD1’s balanced composition gives it strong wear resistance, making it durable against abrasion and mechanical wear. This property is particularly beneficial in applications where the steel is subjected to continuous use and contact with other materials, ensuring that the knife or tool maintains its integrity and performance over time.
Although CTS BD1 excels in hardness and wear resistance, its toughness is moderate. It is resistant to chipping and breakage under normal use but may not be ideal for heavy impact applications. Proper heat treatment can enhance its toughness, making it more versatile for various cutting tasks.
CTS BD1 is processed to reduce impurities and ensure a consistent composition, resulting in predictable heat treatment outcomes and reliable performance. This consistency is crucial for manufacturers who require uniform properties in their materials to produce high-quality, dependable products. As a result, CTS BD1 is widely used in the production of high-performance knives, cutlery, and precision tools. Its combination of hardness, corrosion resistance, and edge retention makes it suitable for applications that demand both durability and sharpness, particularly in premium knives where consistent performance and longevity are critical.
