Forged steel bar, 1045/C45E

Model Number: hot forged steel bar -02 Brand Name: Unite Steel Key Specifications/Special Features: Forged steel bar 1045/C45EApplications:Plain carbon steel for mechanical engineering and automotive components.It is usually supplied untreated but can be supplied to order in the normalized or finally heat treated (quenched and tempered to "Q" or "R" properties), which is adequate for a wide range of applicationsIt is a very popular grade of through-hardening medium carbon steel, which is readily machinable in any condition. It is suitable for the manufacture of parts such as general-purpose axles and shafts, gears, bolts and studs. It can be further surface-hardened typically to 50-55 HRC by induction processes, producing components with enhanced wear resistance.In its heat treated forms possesses good homogenous metallurgical structures, giving consistent machining properties.Related specificationsEuropean: C40, C45, Ck40,Ck45, Cm40, Cm45Germany: DIN 1.1191 DIN1.1201Great Britain:BS970: 1955 EN8, BS970/PD970: 1970 onwards 080M40, 080M46, 060A47France: AFNOR XC 42 TS , AFNOR XC 45 , AFNOR XC 48 , AFNOR XC42
