Amstrong® 550MC
Amstrong® 550MC introduction
Amstrong® 550MC 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 S550MC, SEW QstE 600TM, AFNOR E560D, BS HR60, BS F55, ASTM A1011 HSLAS-F Grade 80 Class 2
