China SAE1045 S45C 1.1191 C45 Carbon Steel Round Bar

SAE1045/S45C/1.1191 Carbon Steel Round Bar
C45 steel is an unalloyed medium carbon steel, which is also a general carbon engineering steel. C45steel is a medium strength steel with good machinability and excellent tensile properties. C45 round steel is generally supplied in the black hot rolled or occasionally in the normalised condition, with a typical tensile strength range 570-700Mpa and Brinell hardness range 170-210 in either condition. It does not however respond satisfactorily to nitriding due to a lack of suitable alloying elements.
1,Feature:
1)Typically used in quenched and tempered or normalized conditions;
2)Good toughness, plasticity and abrasion resistance;
3)High strength and machinability;
4)Medium carbon structural steel;
2,Application:
Use for making injection plastic mould,mould frame and some middle-range machine.
1)Widely used in machine manufacturing;
2)For shaft parts ;
3)Stamping die drawing parts repair and hardfacing;
