Is 420HC a Good Knife Steel?

Are you eyeing a 420HC steel knife but feeling undecided if it will meet your expectations? If yes, you'll find this guide helpful.

420HC steel knives usually come at highly affordable prices but promise you a high-end performance. How true could this be? Many other knife users are always looking for more information about this steel to see if it's worth investing in.

Our complete 420hc steel review below will serve you with helpful information about 420HC and leave you in a better place to easily decide whether to get a 420HC steel knife.

What is 420HC steel?

420HC is a low-end martensitic stainless steel made in the United States by Latrobe. It was developed as a result of modifying 420, very old steel grade. The key change here is adding more carbon content to 420hc, hence its name HC which stands for "Higher Carbon." The steel can also be brought to a higher hardness level than 420.

This steel excels in high corrosion resistance. Many knife manufacturers use it to come up with knives, scissors, surgical tools, etc. Two companies, in particular, Buck Knives and Gerber Knives, intensively use this steel to make their budget-friendly knives.

What is 420HC steel

What is 420HC blade? Any blade made from 420HC steel is simply referred to as a 420HC blade.

420hc chemical composition

The following table outlines the 420HC steel alloying elements and their corresponding volume as see in the manufacturer's 420hc steel datasheet:


Composition (%)











420HC a Good Knife Steel

0.45% 420hc carbon content improves hardness and wear resistance.

13% Chromium improves tensile strength and edge retention. It also enhances the steel wear and corrosion resistance.

0.4% Manganese increases steel hardness and brittleness.

0.3% Vanadium advocates for better wear resistance and hardenability.

0.4% Silicon improves strength.

420hc steel properties

The following 420hc steel mechanical properties will give you a clear picture of how a 420HC blade steel will perform in a knife.

420hc steel properties


What is the 420HC hardness?

When subjected to quality heat treatment, 420HC stainless steel can achieve a hardness as high as RC 56-59 HRC. The standard hardness rating of this steel, however, 55HRC.

420HC edge retention

420HC doesn't hold an edge very well. This is because it contains low carbon content, which translates to low carbide volumes necessary for providing steel with hardness needed to make it stable and sharp. However, it will keep its cutting edge sharp for long compared to other steels in the 400 series.

420HC steel sharpening

Sharpening 420HC is super easy for you, thanks to the fact that it leans on the "softer" edge of steels. It has a low hardness, which makes it less hard. This way, you will quickly be able to sharpen it to obtain an ultra-fine cutting edge. So, if you're just learning the sharpening game, you'd want to invest in a knife made of this steel.

420HC steel toughness

420HC is quite tough! The less hard nature of this steel gives it a tougher feel, and it can withstand a lot of abuse compared to the harder steels in the 440 series. The high toughness explains why Bucks and Gerber have been using this steel for manufacturing their knives for years.

420HC corrosion resistance

You're probably burning with this question: "does 420hc steel rust?" The answer is NO…420HC doesn't rust. It contains 13% chromium, a higher volume than the 11-12% threshold required to make it stainless. The high chromium volume gives it high corrosion resistance—another reason why 420hc enjoys popularity among knife smiths and knife users.

420hc steel comparison with other steels

A wide range of popular steels can be regarded as 420hc steel equivalent due to the identical compositions and almost the same level of performance in all areas. In this part, we'll look at how this steel compares to some of these steels.

420hc steel comparison with other steels

420HC vs S30V

S30V has way higher edge retention and better anti-corrosion properties compared to our steel. However, both exhibit the same level of toughness. Sharpening 420hc is way easier than s30v.

420HC vs 8Cr13MoV

Is 420HC better than 8Cr13MoV? Probably not. While 8Cr13MoV beats in terms of toughness, easier sharpening, and corrosion resistance, 420HC hits back with slightly better edge retention.

420HC vs 440C

The two steels are highly comparable since they exist in the same 400 steel series. They offer pretty similar performance in all areas. Though 440C has slightly better edge retention and corrosion resistance than 420HC.

420HC vs 1095

Apart from both being easy to sharpen, both 1095 and 420hc steels have distinct differences that set them slightly apart. 1095 ranks above 420HC with high edge retention and toughness, but it offers less corrosion resistance compared to 420HC.

420HC vs AUS 6

420hc is also comparable to aus-6 since both contain almost the same levels of carbon and chromium. They deliver similar hardness and corrosion resistance. The high Manganese and silicon content in 420hc, however, makes it a bit tougher than 420hc.

420HC vs 5Cr15MoV

This is another pretty close steel alloy to 420hc as both contain almost the same carbon content, which means they fall in the same hardness level. But the 5Cr15Mov steel features slightly higher chromium and less vanadium content, making it more corrosion resistant and less tough.

Is 420HC steel good for knife?

The 420HC stainless steel is good low-end steel that offers you a good toughness degree and can take a lot of abuse without chipping or breaking. It also sharpens quite easily and achieves an ultra-fine cutting edge without much effort. And yes, this steel delivers high rust and corrosion resistance.

Is 420HC steel good for knife

420HC is also affordable compared to most high-end steels on the market. Despite this, it makes high-performance knives. If you still doubt how good is 420HC stainless steel, you should take note of how many top brands, e.g. Gerber, Buck, S&M, Kershaw, to name but a few, continue using the steel to make some of their most popular knives.
