AEB_L was originally designed for use as razor blade steel. It is famous for a combination of toughness, edge stability, edge retention, being easy to sharpen, and extremely corrosion-resistant. This is an extremely fine-grained steel and stainless steel for many manufacturers.

Heat Treatment:

Hardening Data
Hardening temperature 1060° C, holding time 1.5 minutes per mm thickness, cooling between aluminum plates with forced air.
Tempering Data
2 times for 40 minutes

Brittleness occurs with tempering above 450°C.

Sandvik Hardening Recommendations:

  • Too high hardening temperature gives a coarse structure, high austenite content (30%), few carbides. Consequence: low hardness and poor wear resistance.
  • Too low cooling rate after austenitization produces carbide precipitation at grain boundaries. Consequence: brittleness and reduced corrosion resistance.
  • Optimized hardening conditions yield optimal austenite content (15%), many evenly distributed carbides. Consequence: optimal combination of hardness, wear resistance, ductility, and corrosion resistance.

How Hardening Parameters Influence Product Properties

  • Too high hardening temperature results in low hardness and poor wear resistance due to excessive retained austenite.
  • Low hardening temperature results in low hardness and reduced corrosion resistance.
  • Too long holding time at optimal hardening temperature increases the amount of retained austenite and decreases hardness.
  • Too short holding time at optimal hardening temperature has the same effect as low austenitization temperature.
  • Maximum hardness will be obtained with residual austenite content of about 15%.
  • Deep freezing, i.e., cooling below room temperature, increases hardness by about 1–2 HRC.
  • Deep freezing will achieve maximum hardness possible by increasing hardening temperature.
  • High cooling rate after hardening is necessary to avoid brittleness and reduced corrosion resistance. 600° C should be reached within 1–2 minutes and room temperature within 30 minutes.
  • Re-hardening is generally not recommended as it does not impart optimal properties to the product.

Physical Properties:

The physical properties of a steel are related to a range of factors, including alloying elements, heat treatment, and production route, but the data presented below can generally be used for approximate calculations.
