Highley Steel Ltd
Micro Alloyed Cold Rolled Steel Strip With high yield point for cold forming
HC260LA, HC300LA, HC340LA, HC380LA, HC420LA
Micro alloyed steel is a type of alloy steel that
contains small amounts of alloying elements
(0.05 to 0.15%), including niobium, vanadium,
titanium, molybdenum, zirconium, boron, and
rare-earth metals. They are used to refine the
grain micro-structure or facilitate precipitation hardening.
