Description

Amstrong® 390MC characterised by high ductility, controlled internal purity, fine grain structure and low carbon content. On request, Amstrong® may be delivered with an improved surface finish on black hot-rolled product called MASC (Micro Adhesive Scale). Contact our commercial teams for further information.

It combines:

  • Outstanding mechanical properties
    • High strength
    • Toughness
    • Fatigue resistance
  • Good formability
  • Good weldability


    With its high strength, it is an excellent choice when weight-saving is a priority, and is frequently used to replace structural steels.

Technological properties

Property
Application areas

High strength Amstrong® steels are used in a wide range of applications in transport (earth movers, trailers, agricultural and railroad machinery etc), profiling (racks etc) and building (cranes, safety barriers, light poles etc). Significant weight reductions can be achieved by using Amstrong® steels, especially for cranes and heavy vehicle trailers, thus allowing a larger payload.

Chemical composition

The chemical properties given are based on cast analysis data.

Coating

Galvanisation: Class 1

Suitability for hot-dip zinc coating is defined as per the requirements of EN ISO 14713-2 Table 1 and NFA 35-503.
