6 year agoC45 peeled or turned steel bar
C45 peeled & turned steel bar is medium carbon precision finished steel bar widely used for general machinery spare parts. Manufactured through professional peeling and turning machining processes, this C45 steel bar features ultra-smooth bright surface, tight dimensional tolerance and consistent roundness without oxide scales, burrs or surface defects. Supported by our complete production and inspection equipment, experienced steel technical team and stable raw material suppliers, we supply standard and custom-size C45 peeled turned steel bars with flexible cut lengths, custom tolerances and full MTC certificates for global machinery manufacturers, auto processing factories and hardware component producers.
We a direct steel bar factory located in Laiwu district, Shandong Province, China to produce cold drawn steel bar, peeled, ground and polished bright steel round bar and heat treated steel bar such as annealed steel bar, normalized steel bar and quenched and tempered steel bar. Regarding to C45 peeled or turned steel round bar, we can also do further processing such as shot blasting, polishing, cutting, drilling, chamfering and simple machining etc.
