what is elasticity modulus, is it the same as strenght looking at crucibles site i find elasticity modulus numbers in GPa does that have anything to do with fracture srenght measured in MPa? if not do they correlate in some way? how do i judge strenght before it breaks based on the figures at cricibles site, MPa is good becuse its Newton/mm^2 and that i understand

What mete said.
Can't help with Mpa, but I will guess with some certainty that the numbers you encountered were something like 30 psi x 106. This is because it will be pretty much the same for any steel at a given temperature, which amounts to 30,000 psi to elastically elongate the material 1/1000. It does not necessarily deal with the breaking point but the range in which the steel will still return to its original dimensions or shape after the load is removed. It is a fundamental physical material principle that is most commonly overlooked in bladesmithing, causing the entire field to be mislead that heat treatment can effect how much force it takes to flex a blade... when it can't.
