Effect of 0.09%~0. 14% C content on structure and mechanical properties of 2Mn-0.003B-0.05Ti micro- alloying steel cold drawn with 5%~50% reduction and aged at 100~500 ℃ for 2 h has been studied. Results show that with lower carbon content (0.09%~0. 12%C)
the finer and uniform distributed granular bainite structure in steel is obtained
while with 0. 14% C
the lumpy ferrite shall occur in structure; at same cold-drawing reduction
with increasing carbon content the strength of steel increases and plasticity decreases
and the larger the reduction
the more significant the tendency; and with increasing carbon content the increment of strength of steel aged obviously decreases.
