an unalloyed medium carbon steel, which is also a general carbon
engineering steel. C45 is a medium strength steel with good
machinability and excellent tensile properties. C45 round steel is
generally supplied in the black hot rolled or occasionally in the
normalised condition, with a typical tensile strength range 570 – 700
Mpa and Brinell hardness range 170 – 210 in either condition. It does
not however respond satisfactorily to nitriding due to a lack of
suitable alloying elements.
C45 round bar steel is equivalent to
Steel C45 bar or plate is suitable for the manufacture of parts such as
gears, bolts, general-purpose axles and shafts, keys and studs.

5. Forging of Carbon Steel C45 Round Bar
Hot forming temperature: 850-1200oC.
heat to 750 oC – 800 oC, then continue heating to 1100 oC – 1200 oC
maximum, hold until temperature is uniform throughout the section and
commence forging immediately. Forging is not workable below 850 oC.
Finished forgings could be air cooled.

8. Application of DIN Carbon Steel C45 Round Bar
C45 round bar steel material and steel plate C45, flats are widely used
in all industry for uses which require more strength and wear
resistance than the low carbon mild steel.
subsequently tempered steel for C45 steel grade round bar, steel plate,
flat and square is used for axles, bolts, forged connecting rods,
crankshafts, torsion bars, light gears, guide rods, screws, forgings,
wheel tyres, shafts, sickles, axes, knives, wood working drills,

Low carbon steel is also called mild steel because of its low strength, hardness, carbon content of this type of steel ranges from 0.10% to 0.30%. Low carbon steel is easy to be processed, such as forging, welding and cutting, often used for manufacturing chain, rivets, bolts, shaft, etc. Its carbon content is less than carbon steel whose carbon content is 0.25%. It includes most of ordinary carbon structural steel and part of high quality carbon steels, mostly without heat treatment used in engineering structure, some by carburizing and other heat treatment used for the wear-resisting of mechanical parts.
Annealing organization of low carbon steel contains ferrite and a small amount of pearlite, it has low strength and hardness, plasticity and toughness is better. Therefore, it can use edge, bending, stamping and so on forming methods for cold forming for its good cold forming performance. This steel has good weldability. But as the low carbon content and low hardness, low carbon steel cutability is not satisfying, normalizing treatment can improve the cutability so as to widen the use.
