The 4034 steel, sometimes known as Krupp 4034, is a well-balanced stainless steel that boasts a fine structure and tight chemical composition. It has moderate cutting capabilities and retentivity, while it’s known for its excellent resistance to corrosion. This mid-range steel is typically found in many household kitchen knives and entry-level chef’s knives, which require less maintenance and are not subjected to heavy-duty use.

What are the Benefits of 4034?

The 4034 steel, falling in the mid-range category, is favored for its excellent corrosion resistance and moderate edge retention. It is an economical choice for those who are on a tight budget or those who simply need a reliable knife for everyday tasks. The 4034 steel knives hold up incredibly well against rust, which makes them suitable for use in wet environments, and do not require consistent maintenance.

Being easy to work with and having a pleasant balance between hardness and toughness is another strong point of this steel. Its decent toughness ensures that the knives made from this steel will not chip or break easily even when subjected to harsh treatments.

Disadvantages of 4034 for Knives

Although 4034 steel boasts certain beneficial features, it is not without drawbacks. It has moderate edge retention, which means that it might require frequent sharpening depending upon the extent of its use. Moreover, its performance can't compete with higher-end knife steels in terms of edge sharpness and overall durability.

Another drawback is that the availability of this steel in high-end or diverse knife types is somewhat limited. It is generally found in kitchen knives, rarely seen in survival or EDC knives.

Steel Rating

Steels with good edge retention will stay sharp longer, reducing the need for frequent sharpening

Edge Retention

2/6 Points

Toughness is the steel's ability to absorb energy and deform without breaking


3/6 Points

Corrosion Resistance measures how well the steel can resist rust and oxidation

Corrosion Resistance

4/6 Points

Sharpenability refers to how easily a knife blade can be sharpened to its desired edge


5/6 Points

This is a relative measure based on typical market values. The actual price can vary widel


6/6 Points

A higher HRC number typically indicates a harder steel, which can hold a sharper edge


55 - 56 HRC
Please be aware that this rating should be understood as a comparative measure. It's simply a rough estimation in relation to other knife steels.

How Rust Resistant is 4034?

Due to its remarkable corrosion resistance, 4034 steel is ideal for usage in kitchens or outdoor environments where the likelihood of exposure to water or damp conditions is high. It exhibits a high resistance to rusting and staining, thereby minimizing the regular maintenance works.

How Strong is 4034?

With the hardness ranging from 55 to 56 HRC, the 4034 steel can withstand everyday wear and tear. Its moderate hardness contributes to its solid toughness, making it less prone to breakage or chipping. However, this level of hardness may not be suitable for heavy-duty use as it doesn't retain sharpness for extended periods.

For what is 4034 known for?

The 4034 steel is reputed for its decent quality considering its budget-friendly rate. It has won the trust of users who need a knife that combines rust resistance, economical affordability, and decent toughness. However, it may not be the first pick for knife enthusiasts or professionals who aim for top-notch performance, edge sharpness and superior durability.


In a nutshell, the 4034 steel makes a decent choice for the average user who seeks a balance between price and satisfactory performance. It particularly shines in terms of corrosion resistance, making it a go-to choice for those often dealing with wet conditions. Although it has a compromise on edge retention, with some dedication to maintenance, a 4034 steel knife can serve reliably for a variety of tasks.
