S45C/SAE1045 Steel round bar in stock for plastic mould
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.Related SpecificationsGermanyW.Nr 1.0503 C45
