What is Sandvik 12C27 Steel? Detailed Sandvik 12C27 Steel Review

What is 12C27 steel?

Sandvik AB, a Swedish firm, makes 12C27 steel. It is a low-end high-chromium steel. It is one of two steel grades in the Sandvik group, which includes 14C28N and 13C26 Steel.

The knife industry is fond of 12C27 martensitic stainless, which has excellent wear resistance, corrosion resistance and high hardness. These are all qualities that make it a good knife steel.

This is in contrast to other high-chromium steels, which can be difficult to sharpen due to the hard chromium carides, 12C27 steel achieves an edge quickly. Sandvik 12C27 is used to make hunting knives and pocket knives, fishing knives as well as tactical knives, tactical knives, knife blades, and ice drills.

12C27 steel Chemical composition

  • Carbon 0.60%: Enhances edge retention, hardness and tensile strengths. It increases steel resistance to wear and abrasion as well as corrosion.
  • Chromium Cre 13.50%: Formations of Chromium carbides. This increases the blade’s hardness and tensile strength as well as corrosion resistance.
  • Phosphorous P 0.033%: Enhances steel’s strength and improves its machinability
  • Manganese 0.40%: Increases steel’s strength and hardness. The steel’s hardenability can be improved by adding more manganese to it when it is heated.
  • Silicon Si 0.4%: Increases strength, heat resistance.
  • Sulfur S 0.01 : This improves machinability, but it is considered an impurity when used in large quantities.

Properties of 12C27 Stainless Steel

12C27 Steel Hardness

Sandvik 12C27 steel hardness ranges from 54-61HRC according to the Rockwell hardness scale. This steel’s exact hardness is determined by the heat treatment used by the manufacturer. It is considered hard steel because it can reach 61 HRC.

Sandvik says that too high of a hardening temperature can result in low hardness and poor wear resistance. However, too low hardening temperatures will cause low hardness and corrosion resistance.

12C27 Steel Wear Resistance

Steel’s hardness directly affects its wear resistance. It is clear that 12C27 steel has excellent wear resistance. Although it does not have the same wear resistance as premium knives steels, you can rest assured that your knives will withstand normal wear and tear.

Moreover, the blade will not lose its original shape, even after frequent sharpening. It is less likely to roll on the edges.

12C27 Steel Edge Retention

This Sandvik 12C27 steel is extremely hard and will not become dull. This steel is known for its edge retention and sharpness, which makes it more durable than other steels. This is due to its high carbon and high-chromium content.

The edge retention of 12C27 stainlesssteel is not the best. It falls short of other steels such as crucible’s CPM154 stainless steel or most high-alloy nonstainless steels, like CPM CruWear.

12C27 Steel Corrosion Resistant

12C27 steel is resistant to rust and corrosion. It’s high chromium, which means it resists rusting easily. Stainless steel also resists stains. This steel is a favorite among knife makers for making hunting and fishing knives. This steel is not resistant to all forms of corrosion. It requires regular maintenance and care.

You cannot leave this steel-made knives in water for more than a few days and expect them to not rust. If you want your steel blades to last for decades, it is important that you oil and dry them after each use.

12C27 Steel Toughness

Hard steel is generally considered to be brittle. However, 12C27 is an exception to this rule. Despite its hardness of 61HRC Sandvik 12C27 steel has excellent toughness. This steel’s toughness is due to its fine carbide structure. When used in tough applications, high toughness is resistant to chipping, breaking and cracking.

The 12C27 steel’s toughness is one of the highest in stainless steel blades. Its toughness is comparable to AEB–L steel, 14C28N and 420HC stainless.

Sharpening 12C27 Steel

This 12C27 steel is very easy to sharpen with even the most basic tools, such as a whetstone. This is an unusual feature of 12C27, considering most high-chromium steels can be difficult to sharpen.

12C27 Steel Comparison

Sandvik 12C27 vs D2 steel

Sandvik 12C27 stainless Steel and D2 are different in that 12C27 is stainless steel with more than 13% chromium, while D2 is a nonstainless tool steel.

D2 is a steel that stands out for its wear resistance. While 12C27 is a great steel for its wear resistance, it can’t beat D2.12C27 shines in ease, machinability and toughness. Also, 12C27 knives are less expensive than D2.

12C27 vs. 14C28N

Sandvik’s 14C28N and Sandvik’s 12C27 stainless steels are different in that Sandvik’s 14C28N stainless is an enhanced version of the 12C27 steel. It has more chromium, and more nitrogen.

These elements increase corrosion resistance and toughness slightly more than Sandvik 12C27 Stainless Steel. The development of AEB L steel and 14C28N was preceded by 12C27.

12c27 vs 440C

Sandvik 12C27 and 440C steel are almost identical in toughness. While 440C stainless steel has a slightly better edge retention than 12C27 Stainless Steel, they have almost identical levels of rust resistance.

Both the 12C27 and 440C versions of steel contain a lot of chromium as well as carbon. The carbon content of 440C steel is slightly higher than that of 12C27 steel, which allows for the formation more carbides. These carbides can be used to retain the edge and resist wear in 440C blade steel.

Sandvik 12C27 vs AUS 8

Sandvik 12C27 and Japanese AUS 8 steels have a slight difference in their toughness. These two knife steels will provide almost identical edge retention. Both knives steels will provide the same performance in terms of corrosion and rust resistance.

They offer similar edge retention and corrosion resistance performance. AUS 8 and 12C27 steel have very different compositions. The composition of 12C27 steel is more pure, with mainly carbon-chromium. AUS 8 steel however, has additional elements such as vanadium.

Vanadium and other elements improve AUS-8 steel’s edge retention and wear resistance, but they also affect its toughness by creating hard, brittle carbides. Sandvik 12C27 purity is the best AUS 8 steel substitute for in toughness.

Sandvik 12C27 vs VG10

VG10 has a higher hardness than its counterpart. This makes it more resistant to wear, edge retention and corrosion. 12C27 is tougher than its counterpart and easier to sharpen. 12C27 knives are also more affordable than Japanese VG10 steel knives.

Additional elements such as vanadium or cobalt are responsible for the VG10 steel’s higher hardness. The 12C27 steel composition is more pure, with a majority of carbon and chromium. This allows 12C27 steel to retain its high strength.

Sandvik 12C27 vs 420HC

HTML420HC has lower carbon levels than 12C27. This means that 12C27 has better edge retention. The Vanadium in 420HC makes it more wear resistant than 12C27. These knives are budget-friendly and offer similar corrosion resistance.

Sometimes 12C27 steel can be considered high carbon 420 steel. You will find 12C27 steel with a similar toughness to high-end 420HC but with better edge retention.

12C27 vs 8Cr13MoV

Sandvik 12C27 steel, a low-end Swedish steel, is often compared with Chinese 8Cr13MoV. The steels have similar properties. However, the Chinese 8Cr13MoV steel has a higher hardness because it contains Vanadium, Molybdenum and Nickel.

These additional elements make 8Cr13MoV more wear-resistant and edge retention. The 12C27 stainless-steel has a lower hardness and alloy purity that gives it better toughness.

Is 12C27 good knife steel?

Yes! Yes! It is also easy to sharpen and holds a sharp edge for a long time. These properties depend on how the heat treatment is done.

Sandvik provides clear instructions on how to heat treat this stainless steel in order to get the most out of it. All these properties make 12C27 steel a good choice for knifemakers and knife-users.
