Niolox Steel

Niolox steel, also known as SB1, is a high-performance alloyed steel that combines the excellent edge retention of high-carbon steels with the corrosion resistance of stainless steels – even though it lacks silicon and manganese.

Produced using powder metallurgy by Lohmann steelworks in Witten, Germany, Niolox has an ultra-fine grain structure that significantly improves edge durability and wear resistance.

Chemical Composition

  • 0.8% Carbon
  • 12.7% Chromium
  • 1.1% Molybdenum
  • 0.9% Vanadium
  • 0.7% Niobium

Niobium contributes to the fine-grain structure and edge stability. The steel achieves a hardness of 58 to 63 HRC, offers excellent abrasion resistance, and is easy to sharpen even at low edge angles (18–20 °).

Key Features

  • Hardness between 58–63 HRC
  • High corrosion resistance
  • Exceptional edge stability
  • Easy to sharpen with fine-grit stones

Niolox is a popular choice among knife makers, especially for utility and outdoor knives, where a reliable combination of edge retention, toughness, and corrosion resistance is essential.
