C45 is a medium carbon steel grade offering reasonable tensile strength. Supplied in the cold drawn or hot rolled condition, tensile properties can vary but are approximately between 500-800 N/mm². This grade can be flame or induction hardened to produce a good surface hardness with moderate wear resistance.
What is C45 steel hardness?
C45 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 – 700 Mpa and Brinell hardness range 170 – 210 in either condition.
What is the carbon percentage in C45 steel?
0.40% to 0.50%
C45 steel is categorised as medium carbon steel having 0.40% to 0.50% of carbon and trace amounts of elements like Sulphur, Manganese, Silicon, Phosphorus and Molybdenum in it.
What is the density of C45?
|Density||7.80 g/cc||0.282 lb/in³|
|Hardness, Brinell||165 – 220 @Thickness <=16.0 mm||165 – 220 @Thickness <=0.630 in|
|Brinell||165 – 220 @Thickness 16.0 – 40.0 mm||165 – 220 @Thickness 0.630 – 1.57 in|
Is C45 steel weldable?
In present investigation, development of a standard welding procedure for C45 (AISI 1045) alloy was carried out. The main objective is to improve the weldability of C45 alloy with preheating and post weld heat treatment (PWHT). In the present work, SMAW and GMAW welding processes are used.
What are the 3 grades of carbon steel?
The carbon present in steel is typically reduced so that it fits into three main categories of carbon steel: low (or mild), medium and high carbon steel.
What is a good hardness for steel?
Premium steels range from 59-66 HRC. As modern metallurgy advances, it is entirely possible these numbers might go up. Typically, a good everyday use pocket knife is about 57-59 HRC. You will be perfectly happy with a steel that hard.
Where is C 45 from?
The standard ISO 683-1:2018 supersedes BS EN 10083-2:2006 which also specifies C45. It is a British standard adopted from ISO which specifies heat-treatable steels, alloy steels and free-cutting steels and Non-alloy steels for quenching and tempering.
Why C45 called 1.1191?
European grade 1.1191 steel is a non-alloy carbon steel manufactured for objectively forming into wrought products. 1.1191 is the European numeric designation for this material C45.
