C45R \/ 1.1201 Special Steel is a medium tensile steel supplied as forged or normalized condition. It has a tensile strength of 570 \u2013 700 MPa and Brinell hardness range 170 to 210HB.\u00a0C45R \/ 1.1201 Special Steel offers good strength, toughness,wear resistance and impact properties in either the normalized or hot rolled condition.\u00a0C45R \/ 1.1201 Special Steel\u00a0has a low through-hardening capability with only sections of size around 60 mm being recommended as suitable for tempering and through-hardening. However, it can be efficiently flame or induction hardened in the normalized or hot rolled condition to obtain typical surface hardness up to HRC 58. nitriding is not recommended due to lack of alloy elements.This steel can be readily welded and machined providing correct procedures are followed.<\/p>\n
