Steel C45 Round Bar
is 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 EN8 or 080M40.
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.
Pre
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.
We are strong on forged steel C45 round bar. Welcome enquiry of C45 steel materials.
6. DIN C45 Round Bar Steel Grade Heat Treatment
Forging or hot rolling: | 1100 - 850°C |
Normalising: | 840 - 880°C/air |
Soft annealing: | 680 - 710°C/furnace |
Hardening: | 820 - 860°C/water, oil |

7. Hardening of DIN C45 Steel Hardening
Harden from a temperature of 820-860oC followed by water or oil quenching.
Heat
to 820 oC - 850 oC hold until temperature is uniform throughout the
section, soak for 10 - 15 minutes per 25mm of section, and quench in
water or brine. Or,
Heat to 830 oC - 860 oC soak as above and quench in oil.Temper immediately while still hand warm.

8. Application of DIN Carbon Steel C45 Round Bar
DIN
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.
Quenched and
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,
hammers, etc.
