JIS G4051 S45C H beam,I beam,Channel and Angel Steel

S45C is one kind of high quality high carbon steel,its carbon content is more than 0.4%.S45C has excellent wear resisting property,but it is easy to deformation and cracking during quenching treatment.S45C has good welding and machining performance after spheroidizing.

S20C Chemical Composition:

GRADE	C %	Si %	Mn %	P % max	S % max	Cr
S45C	0.42-0.50	0.15-0.35	0.50-0.80	0.025	0.025	0.20-0.40

S20C Normalized Mechanical properties:

GRADE	Yield Strength  MPa	Tensile Strength   MPa	A,% Min
S20C	460	750	18

S45C H beam,I beam,Channel and Angel Steel have different characteristics and applications.

1,S45C H beam,has high structural strength and structural stability.S45C is also easy to machining,and has a high degree of industrialization.
2,S45C I beam,the section form is high and narrow,its using condition is restricted, S45C I beam should be used according to the design requirements of the drawings.
