AEB-L Steel: The Razor Edge Steel You Need to Know About

on


 

AEB-L steel might not have the fame of premium steels like M390, but it’s a hidden gem that deserves your attention. Known for its razor-sharp edges and versatility, this stainless steel from Uddeholm is a favorite in kitchen knives, razors, and custom blades. In this guide, we’ll explore what makes AEB-L special, its properties, and why it’s a must-know steel for knife enthusiasts in 2025.

What is AEB-L Steel?

AEB-L is a stainless steel originally designed for razor blades, with a composition of 13% chromium, 0.6% carbon, and small amounts of manganese and silicon. Its fine grain structure, achieved through precise heat treatment, allows it to take an incredibly sharp edge. Unlike high-carbide steels like K390, AEB-L prioritizes sharpenability and corrosion resistance.

Key Properties of AEB-L Steel

  • Edge Sharpness: AEB-L’s low carbide content lets it achieve a razor-like edge, perfect for precision cutting.
  • Corrosion Resistance: With 13% chromium, it holds up well against rust, though not as much as M390.
  • Toughness: It’s tougher than brittle high-end steels, resisting chips during light to moderate use (typically 58-60 HRC).
  • Ease of Sharpening: Unlike M4, AEB-L sharpens quickly with basic stones.

Why Choose AEB-L Steel?

AEB-L excels in knives where sharpness trumps edge retention. It’s a budget-friendly alternative to CPM S30V, making it ideal for kitchen cutlery or EDC blades like the Benchmade Tagout 533 (though that uses S30V). Its toughness suits custom makers too.
