Mechanical properties

 

1. Hardness/tensile strength

Cold-rolled special steels are normally supplied as rolled (with a rolled finish), but we can supply products with finishes ranging from the softest annealed finish to the hardest full-hardened finish. This allows you to select the finish best suited to your requirements and application.

Grade	Finishing condition	Hardness test	Tensile test
		HV	Tensile strength N/mm^2	Elongation %
S60C S55C S50C S45C S15C	Annealed	140-180	410-610	28-39
	Skin passed	155-195	460-655	16-36
	Rolled	230-270	705-900	3-17
	Full hardened	250-290	775-970	1-5
