Tensile Strength and Elongation

I need help converting Tensile Strength and Elongation values for sheet metal, type 3cr12. For the Tensile Strength I am going from ksi to N/mm2. The Elongation is a little more confusing, the material value properties that I have is % 18 to 20 and looking for a value in N/mm2. The metric value for Elongation is described a E-Module.

The tensile strength conversion is easy enough, as the units you list are units of pressure, and you can find them on the pressure conversion page here: http://www.onlineconversion.com/pressure.htm

ksi stands for kips/square inch
N/mm² stands for newtons/square millimeter

1 kip/square inch = 6.894 757 28 newton/square millimeter

The elongation conversion will be tougher. When I searched Google, the first link returned was actually your question in this forum, so there is very little out there on it.

I found a link to graphical information program here:

It doesn't answer your conversion question, but they do seem to know about it, so possibly contacting the webmaster there will get your question answered.

The elongation is allways given in %. The important thing is to know the original length for calculating elongation. 5 times diameter or 10 times diameter etc. Otherwise you can not compare the values. E-Modul is young's modulus.

You should also watch out, as your proff stress changes

how to calculate the tensile strengh when in hot condition of the metel ?

hi how can i convert the %elongation on a 25mm diameter of steel?

tensile strenghth 1500lp/in2 =....... n/5cm

What is the conversion from KN. to yield in carbon steel?
