ASTM 1045 / DIN C45 CK45 1.1191 EN8 / 080M40 Carbon Steel Bar / Rod
Steel 1045 Round Bar is an unalloyed medium carbon steel, which is also a general carbon engineering steel. 1045 is a medium strength steel with good machinability and excellent tensile properties. 1045 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.
1045 round bar steel is equivalent to EN8 or 080M40. Steel 1045 bar or plate is suitable for the manufacture of parts such as gears, bolts, general-purpose axles and shafts, keys and studs.
Applications of AISI 1045 Steel
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.

C1045 is forged from around 2200ºF (1205ºC) down to a temperature in the range1650-1700ºF (900-925ºC.) The actual forging and finishing temperatures will depend on a number of factors, including overall reduction during forging and complexity of part being forged. Experience alone will determine near exact values for these two parameters.
Parts are air cooled after forging.
Full annealing of small C1045 forgings is carried out from 1450-1600ºF (790-870ºC)
followed by furnace cooling at 50ºF (28ºC) per hour, to 1200ºF (650ºC) soaking and air cooling.
The normalizing temperature for this grade is typically 1650-1700ºF (900-925ºC.)
Normalizing is followed by cooling in still air. When forgings are normalized before hardening and tempering or other heat treatment, the upper range of the normalizing temperature is used. When normalizing is the final treatment, the lower temperature range is used.
Hardening of this grade is carried out from an austenitizing temperature of 1475-1550ºF (800-845ºC) and oil or water quenching.
Flame and induction hardening may be carried out by heating quickly to the desired case depth and quenching in water or oil. This should be followed by a tempering treatment at 300-400ºF (150-200ºC) to reduce stresses in the case without affecting its hardness. A surface hardness of Rc 58 may be obtained by this treatment.
Tempering after normal hardening and oil or water quenching is carried out at 750-1260 ºF (400-680ºC) to give the required mechanical properties as determined by practical experience.
Machinability of C1045 is good providing the full annealing cycle described above is used, ensuring a coarse lamellar pearlite to coarse spheroidite microstructure.
This grade is readily welded with the correct procedure. Welding in the through hardened or flame or induction hardened conditions is not recommended.
Low-hydrogen electrodes are recommended together with preheat at 400-570ºF (200-300 ºC.) to be maintained during welding, Cool slowly in sand or ashes and stress relieve where possible.
