1045 Medium Tensile Carbon Steel Bar

1045 is a medium tensile low hardenability carbon steel 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.

Characterised by fairly good strength and impact properties, plus good machinability and reasonable weldability in the hot rolled or normalised condition.

1045 has a low through hardening capability with sections up to around 60mm only generally recommended as suitable for through hardening and tempering. It can however be successfully flame or induction hardened in the as rolled or normalised condition resulting in surface hardnesses of up to Rc 54 - Rc 60 depending upon quenching medium employed, type of set up, section size etc. Core strengths will remain as supplied.

It does not however respond satisfactorily to nitriding due to a lack of suitable alloying elements.

1045 is used extensively by all industry sectors for applications requiring more strength and wear resistance than the low carbon mild steels can provide and the higher strength of the low alloy high tensile steels is not necessary, plus those applications requiring flame or induction hardening.

Typical applications are: Axles Various, Bolts, Connecting Rods, Hydraulic Clamps and Rams, Pins Various, Rolls Various, Studs, Shafts, Spindles etc.

Forging
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. Do not forge below 850 ^oC Finished forgings may be air cooled
Heat Treatment
Annealing
Heat to 800 ^oC - 850 ^oC hold until temperature is uniform throughout the section, and cool in furnace.

Forging

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.

Do not forge below 850 ^oC

Finished forgings may be air cooled

Heat Treatment

Annealing

Heat to 800 ^oC - 850 ^oC hold until temperature is uniform throughout the section, and cool in furnace.

Hardening

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.

Normalising

Heat to 870 ^oC - 920 ^oC hold until temperature is uniform throughout the section, soak for 10 - 15 minutes.

Cool in still air.

Stress Relieving

Heat to 550 ^oC - 660 ^oC hold until temperature is uniform throughout the section, soak for 1 hour per 25mm of section, and cool in still air.

Tempering

Re heat to 400 ^oC - 650 ^oC as required, hold until temperature is uniform throughout the section, soak for 1 hour per 25mm of section, and cool in still air.

Notes on Heat Treatment

Heating temperatures, rate of heating, cooling and soaking times will vary due to factors such as work piece size/shape, also furnace type employed, quenching medium and work piece transfer facilities etc.

Please consult your heat treater for best results.

Machining

1045 in the hot rolled and normalised condition has very good machinability and all operations such as sawing, turning, drilling, broaching, milling and tapping etc. can be carried out satisfactorily using machine manufacturers recommendations for suitable tool type, feeds and speeds.

Welding

1045 is readily weldable in the as rolled and normalised condition providing the correct procedure is employed.

Following welding the work piece immediately upon cooling to hand warm should be stress relieved at 550 ^oC - 660 ^oC if possible.

NB. Welding in the hardened and tempered, flame or induction hardened condition is not recommended.

Welding Procedure

Welding of 1045 should always be carried out using low hydrogen electrodes.

Please consult your welding consumables supplier.
