“…Therefore, the temperature range for embrittlement is similar for both internal (i.e., for a leaded steel, as described earlier) and external (i.e., pretinning the steel surface with Pb) Pb wetting. Another type of steel (AISI 3340) was soon found to be susceptible to LME by Pb soldering [343].…”

“…LME experiments with AISI 4145 steel showed that both fracture strength and ductility decreased in a continuous manner at temperatures considerably below the melting point of lead, and reached a minimum just above the melting point, and then increased rapidly [15]. Experiments with AISI 3340 steel showed loss of ductility in the temperature range of 315--427°C [16]. Chromesco 3 steel showed a slight decrease in the reduction of area (10%) and ultimate tensile strength in the temperature range between 327 and 350°C [10].…”

“…These are softened or melted to be played as lubricants at interfaces between chips and machining tools, which prevents the wear of machining tools. [1,[4][5][6] Pb-S-based free-machining steels have been widely used so far, but the need for replacement for these steels has been strongly suggested. This is because they contain a considerable amount of Pb, which is harmful for human bodies and generates lead fumes during the machining and recycling processes.…”

In this study, cracks or scabs formed during hot rolling of Bi-S-based free-machining steel wire rods were analyzed, and their formation mechanisms were clarified in relation with microstructure. Detailed microstructural analyses of large-diameter rods showed that the rod having low carbon content was cracked, whereas the rod having higher carbon content was not, because oxides formed during hot rolling were penetrated into the relatively soft surface, thereby leading to the surface cracking. While the crack-free, large-diameter rod containing high carbon content was subsequently rolled to make a small-diameter rod, a few scabs of 1 to 2 mm in size were formed on the surface as some protrusions were folded during hot rolling. Thus, in order to prevent the cracking or scab formation in wire rods, (1) the increase in hot-rolling temperature for homogeneous rolling of rods, (2) the minimization of temperature drop of rolled rods upon descaling treatment, and (3) the increase of rolling passes and the decrease of reduction ratio of each pass were suggested. Using these methods, crack-or scab-free wire rods could be successfully fabricated.
