Performance Traits
Hardness
Sandvik 12C27 steel has a high level of hardness due to its chemical composition. The steel contains 0.60% carbon, which increases edge retention, hardness, and tensile strength. The hardness of this steel also contributes to its excellent wear resistance, making it suitable for daily use without concern for wear and tear.
Edge Retention
With a higher carbon content than several widely used alloys, Sandvik 12C27 steel possesses enhanced edge retention. Its performance compares favorably to AUS 8 and ATS-34, both well-known premium alloys. The steel’s hardness and high chromium content (13.5%) work together to maintain the sharpness of the knife edge during prolonged use.
Toughness
Sandvik 12C27 steel has an impressive level of toughness, thanks to 13.5% chromium in its composition. This element boosts tensile strength, hardness, and toughness, making the steel capable of withstanding impact and resisting chipping when used in various cutting tasks.
Corrosion Resistance
The high chromium content in Sandvik 12C27 steel plays a significant role in increasing its corrosion resistance. When the chromium content is more than 12%, it ensures the steel maintains its stainless properties. Consequently, this steel is highly resistant to rust and other forms of corrosion, making it suitable for use in humid or wet environments.
Sharpening
Even though Sandvik 12C27 steel has excellent edge retention, it is still relatively easy to sharpen when required. This attribute is helpful for knife users who need to maintain the sharpness of their knives frequently. The steel’s high corrosion resistance also ensures that the sharpening process does not lead to unintended surface damage.
Machinability
Sandvik 12C27 steel possesses good machinability, due in part to its 0.25% phosphorous content. This element increases the steel’s strength and machinability, making it easier to shape and work with during the manufacturing process. As a result, knives made from Sandvik 12C27 steel have clean and precise lines, enhancing their overall aesthetic appeal.
Comparison with Other Steels
420HC
420HC steel is a budget-friendly option that offers decent corrosion resistance but has relatively low hardness. Compared to Sandvik 12C27, 420HC steel is less wear-resistant and may require more frequent sharpening.
440C
440C steel is another type of stainless steel known for its high chromium content, which provides good corrosion resistance. However, Sandvik 12C27 offers a finer carbide structure, resulting in greater toughness, higher sharpness, and better edge stability, while 440C has slightly better wear resistance.
8Cr13MoV
8Cr13MoV steel is a popular Chinese stainless steel known for its affordability and decent performance. While both Sandvik 12C27 and 8Cr13MoV offer good corrosion resistance, the Sandvik 12C27 has better edge retention and sharpness.
D2
D2 steel is a high-carbon, high-chromium tool steel known for its excellent wear resistance. It is a non-stainless steel with great edge retention but may be more prone to corrosion. Sandvik 12C27, on the other hand, offers a balance of corrosion resistance and edge retention, making it more versatile for a variety of applications.
14C28N
14C28N steel is another Sandvik stainless steel and is a direct upgrade of 12C27. It offers improved corrosion resistance, increased hardness, and slightly better edge retention compared to 12C27, but may be a bit more challenging to sharpen.
VG10
VG10 steel is a high-performance stainless steel from Japan, typically found in premium knives. It provides excellent edge retention, hardness, and corrosion resistance. However, it may be more challenging to sharpen compared to Sandvik 12C27.
S30V
S30V steel is a premium stainless steel developed by Crucible Industries. It is known for its excellent edge retention, hardness, and corrosion resistance. Although Sandvik 12C27 offers good performance, S30V steel outperforms it in terms of edge retention and corrosion resistance.
AEB-L
AEB-L steel is another stainless steel used in knife making. Its main advantage is its ability to achieve a fine, mirror-like finish and excellent sharpenability. While Sandvik 12C27 offers comparable performance in terms of hardness, corrosion resistance, and edge retention, AEB-L excels in achieving a sharper edge and better polish.
Common Applications
Sandvik 12c27 steel is a popular choice for a variety of knife types due to its excellent combination of corrosion resistance, edge retention, toughness, and ease of sharpening. This versatile steel is used in a range of applications, providing strength and durability for different types of blades.
