A2 steel vs D2 | Which is Better?
If you’re searching for air-hardening steel tools on an affordable budget? Then you can’t ignore the popular steel A2 and D2 steel. Both A2 and D2 have opposite advantages and disadvantages. So, it’s quite tough to select one between them. But, a short comparison can help you better.
You’ll find many differences between A2 vs D2 tool steel. A2 steel is very popular for its toughness & wear resistance. Whereas D2 wins the heart for its superior corrosion resistance, better edge retention, and good hardness compared to A2 steel. Again, A2 steel is easy to sharpen, but D2 is hard to sharpen.
However, you can feel confused about what you should buy. Only the overview and detailed comparison between A2 and D2 tool steel give you a clear decision. So, find the right one with this entire article.
About A2: Short Overview
A2 steel is the most common air-hardening tool. It’s not stainless steel as it has only 5.50% chromium. A2 steel is tougher than other stainless steel. So, it shows good wear resistance as well.
But, with less chromium percentage, it doesn’t have enough anti-corrosion resistance properties and good edge retention. Well, it’s a great choice for hiking and camping on an affordable budget.
About D2: Short Overview
D2 steel is an air-hardening tool and almost acts as stainless steel. The perfect blend of high carbon, chromium, molybdenum & vanadium makes it extremely great for hardness and corrosion resistance.
However, D2 steel has decent toughness & good edge retention. So, you can get a rounder performance with this cheap steel blade than with expensive stainless steel.

A2 vs D2 tool steel: Key differences
Both A2 and D2 steel are very different from others. So, it’s more than a choice according to which benefits you need from your steel. Let’s explore more with a detailed comparison
1. Hardness
Although both steel almost shows the same range of hardness. But, D2 offers slightly better hardness than A2. So, definitely, D2 won the first round over A2 Steel.
According to the Rockwell Report, A2 has a hardness of 57-62 HRC, whereas D2 offers 52-62 HRC.
2. Toughness
The harder the steel, the less tough it is! That means A2 is tougher steel than D2. In this stage, A2 wins a plus point and competes with A2 easily!
A2 has enough toughness to resist chipping or breaking, whereas D2 doesn’t show that much toughness.
3. Corrosion resistance
D2 will win a big point in this round. Because it has superior corrosion resistance compared to A2 steel.
D2 has 12% chromium, which resists any corrosion or rust under humid conditions, moisture, or salt. Whereas A2 has only 5.50% chromium, which is very low to show much corrosion resistance.
4. Edge retention:
Hard steel can hold the edge longer. So, obviously, D2 offers greater edge retention than A2 steel. Again, D2 competes easily with the A2 steel and wins the round.
5. Ease of sharpening
The less hard steel is easy to sharpen. That’s why sharpening A2 steel is easier than D2 steel. So, A2 is still in the race to win this last round.
Although D2 is hard to sharpen, it doesn’t require frequent sharpening like A2. If you want to know more about knife sharpening read how to sharpen a knife without damaging it.
My opinion (Which I Recommend)
You have to explore many things! Right? At the end of the era, I’m going to give you a simple suggestion.
I think you should buy D2 steel as it works as an all-rounder, including great corrosion resistance, hardness, and sharp edge for a longer period.
Again, A2 steel will give you better toughness and wear resistance. But, it’s not good for corrosion resistance and edge retention. So, the decision is yours! Check which one fits your needs.
