For example, SWRH 37A, SWRH 37B, SWRH 42A and SWRH 42B are arduous metal wire that comprise 0.4% carbon. Meanwhile, Mo is ready to reduce the possibility of community cementite existing on the grain boundaries, which is helpful for increasing the plasticity of the high-carbon steel wire rod. Manganese (Mn) factor is beneficial as a deoxidizer, as with Si; successfully contributes to higher strengths of the wire rod; and, in addition, fixes sulfur within the steel as manganese sulfide MnS to forestall sizzling embrittlement. By contrast, with a content more than, carbon offers rise to professional-eutectoid cementite, which deteriorates drawability. Pearlite texture varieties on the wire rod or wire heart portion in a pearlite wire rod or wire handled at a isothermal transformation temperature exceeding 500掳 C. Since pearlite texture has a laminar construction of cementite and ferrite, it makes a significant contribution to work hardening, however a lower in ductility can’t be prevented.

Generally scorching rolling of bearing metal, the material is heated to the austenite single-phase region and rolled in the austenite state. In contrast, a wire rod having an excessively excessive Si content material may endure from poor ductility of the ferrite section within the pearlite construction and should suffer from poor ductility after wire drawing. offers 171 13mm low carbon metal wire rod merchandise. JIS G-3506 is usually a good reference for the Carbon metal wire rods and is extensively adopted by world wire rod producers.
