How good is 4034 steel

How Good is 4034 Steel?

If you’re new to the knife world, or simply less knowledgeable about blade steels, and you come across a 4034 stainless steel with a good price point, you’ll instantly get curious about this steel grade and want to know more about its performance.

If that’s what you’re going through right now, we have done lots of research and prepared this 4034 steel review to offer you important information about the 4034 Krupp steel like its edge stability, corrosion resistance, toughness, how it resharpens, and so much more.

What is 4034 steel?

4034 is a low steel alloy produced by Krupp, the German-based Steel manufacturers. It features average carbon content and is considered a softer steel grade compared to most of the high-end steels available for knives.

The low alloy steel hangs on the lower end of the knife steel scale and is usually associated with budget fixed blades and folding knives.

What is 4034 steel

4034 steel delivers relative hardness and corrosion resistance which makes it popular for kitchen knives, diving knives, and utility knives. You can get decent quality 4034 stainless steel knives from top manufacturers like Smith & Wesson, Cold Steel, Schrade, and Booker.

4034 steel composition

4034 is a low alloy steel with a pretty simple chemical composition. It compromises 3 elements ONLY as outlined in the following table.


Percentage composition (%)

Carbon (C)


Chromium (Cr)


Manganese (Mn)


4034 Steel

0.50% Carbon increases hardness and wear resistance. It also improves corrosion resistance.

14.00% Chromium is more than the 13% volume needed to make 4034 stainless. High chromium content increases tensile strength, edge retention. It also improves wear and corrosion resistance.

0.10% Manganese increases brittleness and hardness.

NOTE that some manufacturers tend to add 1% silicon to their 4034 steel composition.

What is 4034 stainless steel hardness?

The 4034 steel hardness ranges from 54 to 58 HRC. This is perfectly in line with what we stated earlier that the 4034 steel is considered softer steel. High-hardness steels have Rockwell hardness of 60RC and above, so you can easily the “soft” nature of this steel grade.

4034 steel properties

Owing to its simplistic 3-element chemical composition, you don’t expect 4034 steel to offer the same list of attributes as other top blade steels.

4034 steel properties

Let’s see what a 4034 stainless steel knife has in store for you…

4034 steel wear resistance

the steel has good wear resistance, but not the best. remember hardness and wear resistance ego hand in hand. And low hardness means low wear resistance. With that being said, this steel isn’t the worst. It still offers decent wear resistance and can put up with normal wear and tear and still perform reliably.

4034 toughness

This is one department where 4034 steel excels. A quick look at its chemical composition, you’ll notice that this steel doesn’t feature many elements that contribute to high toughness as in other super-tough steels out there. But it contains high chromium levels which give it adequate toughness to stand up to heavy-duty use. 4034 steel blades can handle a good amount of abuse without giving in to chipping or breaking.

4034 corrosion resistance

Another department where 4034s performs well is resisting corrosion and rusting. Remember, this steel features 14% chromium which makes it stainless. As such, it can withstand humid and marine conditions—the reason it finds favor in making diving and kitchen knives. That said, we still urge you to give it simple maintenance like cleaning and drying the blade after every use to ensure maximum resistance to corrosion.

4034 sharpenability

Since 4034 lies on the softer side of the steel spectrum, it should take an edge easily and without any issues. And when sharpened correctly, it can take an ultra-sharp edge that makes it a reliable cutting tool. However, keep in mind that your sharpening skill will determine how easy this steel sharpens. If you’re a newbie sharpener, you might struggle to give it a sharp edge. In this case, try changing the angle to see if the experience gets easier.

4034 sharpenability

4034 edge retention

Soft steels don’t hold an edge for long. 4034 is one such and won’t hold a sharp edge as long as a super-steel with high hardness will do. But the good news is that it doesn’t lose its sharp edge right away. It offers decent edge retention, so you won’t have to worry about the edge dulling in the middle of a cutting job. The steel compensates for this by being incredibly easy to sharpen than the harder steels.

What is 4034 steel equivalent?

Going by the chemical composition, 4034 stainless steel is closer to 420HC and 420J2. All three steels fall in the low-end steel realm. But 420HC and 420J2 have more alloying and tend to perform better in key areas compared to 4034 steel.

4034 steel comparison with other steels

How does steel compare with other popular knife steel grades? This is exactly what we’ll be looking at in this section. We’ll do a quick comparison between Krupp 4034 steel and a handful of popular steels in key features like edge retention, corrosion resistance, and ease of sharpening.

4034 steel comparison with other steels

4034 steel vs 440C

440C is standard stainless steel with higher chromium content, making it more rust and corrosion-resistant. The steel also contains double the volume of carbon in 4034, making it harder and stronger than 4034. The only reason you should get a 4034 steel knife over the 440c steel knife is affordability.

4034 vs AUS 8

AUS is higher-grade steel from Japan and comes with a well-thought-out chemical composition to ensure it balances good hardness, toughness, corrosion resistance, and machinability. In comparison to our steel, AUS 8 has higher hardness, better edge retention, wear resistance, and corrosion resistance, and is generally offers better performance than 4034 stainless steel.

4034 steel comparison with other steels

4034 vs 4116

4116 is also a low-end steel grade found in budget-friendly knives. It contains slightly higher chromium (15%) than 4034 and offers excellent corrosion resistance, making it synonymous with knives used in humid and marine conditions. It features a more elaborate composition of elements and will beat 4034 in terms of edge retention and toughness.

Is 4034 steel good for knives?

4034 stainless steel is good if you’re looking for an entry-level or budget-friendly knife with decent quality and performance.  Keep in mind that this steel is nothing compared to high-end steels. Nonetheless, it can offer good corrosion resistance, decent toughness, and sharpening it is a breeze.

If you’re looking for a budget-friendly knife for use in wet conditions, 4034 steel knives are a great option. Also, if you want a great EDC carry knife with a good price point, consider the 4034 steel.

But if you’re looking for tremendous wear resistance, excellent edge retention, and great toughness, 4034 is NOT the steel for you.
