Product Description
1045 Medium Tensile Carbon Steel Bar for Injection Mold

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.

As a mould steel, it is used for making injection plastic mould, mould frame and some mid-range machines.

ForgingPre heat to 750ºC - 800ºC, then continue heating to 1100ºC - 1200ºC maximum, hold until temperature is uniform throughout the section and commence forging immediately
AnnealingHeat to 800ºC - 850ºC hold until temperature is uniform throughout the section, and cool in furnace
HardeningHeat to 820ºC - 850ºC 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 830ºC - 860ºC soak as above and quench in oil.Temper immediately while still hand warm
NormalizingHeat to 870ºC - 920ºC hold until temperature is uniform throughout the section, soak for 10 - 15 minutes.Cool in still air
TemperingRe heat to 400ºC - 650ºC as required, hold until temperature is uniform throughout the section, soak for 1 hour per 25mm of section, and cool in still air.


Application
