If you are a fan of German steel variants for kitchen knives, you may have already used a knife made up of X50CrMoV15 steel. This famous German steel is considered analogous to kitchen knives. If you shop for a chef or kitchen knife now, the probability of getting a high-quality knife made up of this steel and from an esteemed brand is high. So, in this post, let’s find out more about this steel to know whether it can be a reliable option for you or not.

What is X50CrMoV15 Steel?

X50CrMoV15 is a type of martensitic stainless steel produced by German manufacturers. Although there are some deceiving allegations, X50CrMoV15 does not belong to the family of high-carbon steels.

This steel is widely used in making a variety of kitchen knives such as choppers, cleavers, paring, and utility. It is also used for making all-purpose shears. The main reasons makers use it for kitchen knives are its excellent cutting traits and great ability to put corrosion at bay.

The incomprehensible name, X50CrMoV15, has a special meaning. It is not simply a set of randomly selected digits and letters. Each of them has a meaning. X indicates that it is a kind of stainless steel. 50 means the percentage of carbon in the steel. Cr represents chromium, while Mo indicates the presence of molybdenum.

V means that there is vanadium in this steel, while 15 indicates the chromium content. Such a naming convention also indicates that the Germans made this steel by using many metals.

Chemical Composition

As the name indicates, X50CrMoV15 has more chromium (15%) and relatively less carbon (0.5%). Although not a high-carbon variant, the presence of 0.5% carbon makes it a type of moderately high-carbon steel. Following are the components of this steel:

  • 0.5% Carbon: For better hardness as well as the ability to keep wear or corrosion at bay
  • 15% Chromium: For great tensile strength, reliable ability to retain an edge, and better power to resist wear as well as corrosion
  • 1% Silicon: For boosted strength.
  • 1% Manganese: For better hardness as well as brittleness
  • 0.8% Molybdenum: For boosted strength as well as machinability (flexibility during manufacturing process)
  • 0.20% Vanadium: For better hardenability as well as resistance to wear
  • 0.015% Sulfur: For better flexibility during the manufacturing process
  • 0.04% Phosphorus: For boosted strength

The mix of high chromium and the small molybdenum content ensures greater resistance to corrosion than the ordinary martensitic steel variants. Similarly, the mix of molybdenum and vanadium helps in boosting the grain structure and increasing longevity.


On the Rockwell scale of hardness, X50CrMoV15 has a rating of 56 HRC. Nevertheless, this rating can be between 52 and 56, as per the heat treatment given by the manufacturer. It is considered a good range of hardness, as it is neither too hard nor too soft.

The rating of 56 HRC is attributed to enough carbon. Well, this is sufficiently hard for cutting food items in the kitchen. At the same time, it is not that hard to make you cautious about chipping, although the sustenance of a sharp edge is not excellent.

Following are the properties of the X50CrMoV15 steel:

  • High Rust and Corrosion Resistance: This property tells you why this steel is so widely used for making kitchen knives. The chromium content of 15%, which is enough to render any steel stainless, along with molybdenum, keeps stains and rust away, especially in humid and wet regions.
  • Excellent Wear Resistance: The level of hardness of X50CrMoV15 is enough for the blade to last for several years by keeping the wear impact away, even if it is used too frequently.
  • Great Sharpness: This is another reason why X50CrMoV15 is used for making kitchen knives. The edge of a knife made using this steel comes razor-like sharp.
  • Good Toughness: This steel ranks high when it comes to measuring toughness. Due to the high toughness level, it is not a kind of super-hard steel. It is impressive to see how the blade can endure shock, impact, chipping risk, and lateral forces when used with tough cutting jobs. This is what you want, as harder steels will never be this tough.
  • Good Edge Retention: Due to low carbon as well as vanadium amount, this steel does not have extremely hard carbides. In simple words, it cannot hold its edge for a very long time. The ranking for this ability is lower than the high-end variants. For you, it means this steel is not a good choice for a camping knife or abrasive cutting. However, it is reliable for cutting veggies and fruits, as it will sustain the sharpness for a satisfactory long time.
  • Ease of Sharpening: It is extremely simple to sharpen an X50CrMoV15 edge. This is attributed to the moderate carbon content, due to which X50CrMoV15 is not that hard. Consider this steel if you have just started learning how to sharpen an edge of a knife blade. You will be able to accomplish a razor-sharp edge easily as well as quickly without using an advanced sharpening tool. Any normal honing steel is enough for sharpening this steel’s edge. This ease of sharpening is a bonus when you consider that X50CrMoV15 cannot hold its edge for a reasonably long time.

X50CrMoV15 vs. Other Knife Steel Options

You will have a more precise idea about how this steel truly performs if you compare it with other steel variants having similar features. You may either get a better alternative or a confirmation that this steel is the right option for you. So, let’s compare!

X50CrMoV15 versus AUS10

The latter wins over the former in terms of edge retention ability. However, X50CrMoV15 is tougher and easier to sharpen.

X50CrMoV15 versus VG10

The latter is a type of high-carbon steel and has a superb edge-retention ability. Nevertheless, it is somewhat harder to sharpen. X50CrMoV15 is tougher than VG10.

X50CrMoV15 versus 440C

The latter steel has a higher level of corrosion resistance and holds its sharp edge better than X50CrMoV15. However, X50CrMoV15 is tougher and somewhat easier to sharpen than 440C. As 400C is not as tough as X50CrMoV15, it is likely to chip off.

X50CrMoV15 versus X30Cr13

The latter steel is softer than the former due to fewer quantities of carbon, vanadium, and molybdenum. Thus, it does not retain its edge well. However, X30Cr13 is better at preventing chipping and is easier to sharpen.

X50CrMoV15 versus 8Cr13MoV

The latter steel is an affordable option from China and is widely used by esteemed knife brands. However, just like X50crMoV15, it does not retain a sharp edge very well. It is also not that resistant to corrosion, due to which it is used for making EDC knives.
