Amstrong® 420MC
Amstrong® 420MC introduction
Amstrong® 420MC 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.
Equivalent material: EN S420MC, SWE QstE 460TM, UNE AE440HC, AFNOR E420D, BS HR50, BS F45, ASTM A1011 HSLAS-F Grade 60 Class 2
