Tata Astrum EN 10149 S550MC

Tata Astrum EN 10149 S550MC is a hot-rolled steel grade typically used in structural fabrication, PEB sections, automotive chassis, agricultural implements, general engineering. It is rolled at high temperature above the recrystallisation point, leaving a mill-scale surface and broader tolerances than CR. VVS stocks EN 10149 S550MC at our authorised distributor yard and ships against your spec from order date.

Mechanical properties are reported on the mill-test certificate that ships with every coil and follow the relevant Indian/international standard. Indicative values for EN 10149 S550MC are captured in the spec table on this page; the brochure download has the authoritative ranges for yield strength, tensile strength, elongation and (where applicable) hardness and impact behaviour.
