I need to know the hardness for c - 45 steel.
60hrc
Yes.
Minimum hardness of Mild steel is about 140 Vickers hardness.
In Vickers hardness test the for used is much lighter than the force used in Rockwell hardness test, The Rockwell hardness test is the considered to be the most routinely used technique to measure the hardness of materials because of its simplicity and because it does not require specific skills in order to perform it.
The Rockwell C Hardness system uses "HRC" as a measure of hardness for various materials. A hardness of 68 HRC is extremely high and will most likely be harder than simple steel.
please give me chemical composition of c45 Chemical composition in weight %: 0.42-0.50% C, <0.40% Si, 0.50-0.80% Mn, <0.045% S, <0.045% P, 0.40% Ni, <0.40% Cr, <0.10% Mo, Cr+Mo+Ni<=063. Note: Carbon steel. Austenitized at 850 oC. Source: Website Saarstahl AG, Germany, 2007.
below 380 HV10
Yes.
Yes.
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
Designation by Standards Brand Name Ravne No. Mat. No. DIN EN AISI C45 516 1.0503 C45 - 1045 Chemical Composition (in weight %) C Si Mn Cr Mo Ni V W Others 0.46 max. 0.40 0.65 max. 0.40 max. 0.10 max. 0.40 - - (Cr+Mo+Ni)= max. 0.63
yes, both the grades have equal chemical and mechanical properties
what is the difference between Shore-A Hardness & Barcol Hardness
no one likes your Hardness! hardness is not a good character.
The hardness of conundrum is 9 on the Moh's hardness scale
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
I don't found the Mohs hardness of plutonium but: - the Brinell hardness is 242 at r.m. - the Vickers hardness is 255 at r.m. After a hardness conversion chart an equivalent Mohs hardness may be 3,7.
Mohs hardness: 6 Brinell hardness: 196 MPa.
