Manufacturing method of hot rolled ferritic stainless steel wire with less surface defects

摘要

The present invention adds a trace alloy element to SUS 430 stainless steel to increase the hot deformation resistance of the matrix structure and to reduce the austenite fraction at high temperature and to reduce the hot rolling temperature due to the decrease in the heating temperature of the billet in the hot rolled preheating furnace. It is an object of the present invention to provide a method for producing a ferritic stainless steel wire having excellent hot deformation resistance by reducing surface bonding in a range in which the rolling temperature is not significantly lower than the hot rolling conditions while simultaneously considering the deformation resistance.;In order to achieve the above object, the present invention is a weight%, C: 0.15% or less, Si: 1.0% or less, Mn: 1.0% or less, Cr: 16-18%, Ni: 0.5% or less, Mo: 0.5% or less, Nb: 0.01 ~ 0.1%, ferritic stainless steel composed of residual Fe and other unavoidable impurities are extracted by heating to a temperature range of 870 ~ 930 ℃, hot rolled to produce a hot-rolled ferritic stainless steel wire with a low surface bonding The idea is to provide a method.
