AISI 1045 Carbon Steel Suppliers - S45C , ASSAB 760 , 1.1191 , EN9 , CK45 


Carbon Steel AISI 1045 is a medium tensile low hardenability carbon steel generally supplied in the cold drawn or turned and polished condition, with a typical tensile strength range 600 – 950 Mpa and Brinell hardness range 179 – 280. in either condition.

Characterised by good strength and impact properties, with good machinability and reasonable weldability in the as supplied condition.

Material S45C 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 supplied 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.
EN9 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.

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 of AISI 1045 Carbon Steel 

Annealing

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

Flame or Induction Hardening

Heat as quickly as possible to the austenitic temperature range (820 oC – 860 oC) and required case depth followed by an immediate water or oil quench, depending upon hardness required, workpiece size/shape and quenching arrangements.

Following quenching to hand warm, most components should be tempered at 150 oC – 200 oC to remove quenching stresses in the case. This will have little effect on case hardness.


Hardening of CK45 Steel 

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.



Carbon Steel S45C steel- Normalizing

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.
 

S45C steel 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.

Machining of 1.1191 Medium Carbon Steel 

1.1191 carbon steel in the cold drawn or turned and polished condition has very good machinability and all operations such as turning, drilling, broaching, milling and tapping etc. can be carried out satisfactorily using machine manufacturers recommendations for suitable tool type, feeds and speeds.
