Study on the Aging Regularity of SWRH82B Hot-Rolling Wire Rod
Through study on the regulation of tensile strength and reduction of area after artificial aging and natural aging for SWRH82B wire rod, indicate that the tensile strength of wire rod unchanged through artificial aging or natural aging treatment while the reduction of area changes significantly the reduction of area is effected by aging temperature and aging time. Reduce the residual stress in the wire rod and lattice distortion is the main reason for reduction of area improving the composite brittle inclusions in the wire rod are not good for the rod plastic recovery.
