Yes.
Steel Radial Speed Rating
Presumably C means circumference and R means radius? If C = 2*pi*R Then R = C divided by 2*pi
That is the formula for the area of a circle; r refers to the radius, and pi is approximately 3.14. r squared means that you multiply r x r.
(3) x (r) which means 3 times its radius.
the equivalent for c45 is en-8 and en-19 is c55 Need the Chemical composition and mechanical properties of C45 and EN-8 also to C55 and EN-19
I need to know the hardness for c - 45 steel.
No, the chemical composition of C45 and EN8D steels are different. C45 is a European standard designation for a medium carbon steel, while EN8D is an Indian standard grade for a medium carbon steel. It is important to check the specific chemical composition of each grade to ensure suitability for the intended application.
C45 is a medium carbon steel with good machinability and hardenability, primarily used for making gears, shafts, and machinery parts. En9 is a low carbon steel with good tensile strength and toughness, commonly used in general engineering applications and automotive components. The main difference lies in their carbon content and the resulting mechanical properties.
Yes.
Yes.
The typical hardness values for C45 steel is around 167-229 HB, for ST52 it is around 201-255 HB, and for SAE4140 it is around 217-249 HB. Hardness values can vary depending on the specific heat treatment and processing of the material.
