The fatigue strength of mild steel refers to the certain conditions whereby the mild steel suffers fatigue failure.
i think that it is quite difficult to cut mild steel because of its stiffness/strength
it is the resistance of material to impact(sudden) loading...or..it is the impact energy absorbed per unit area.

the tensile strength, hardness and yield strength of steel depends on the amount of carbon in it. this is because amount of pearlite increases linearly with % of C in steel from 0-0.77%. Elongation (ductility) is caused by the ferrite in the steel which forms plastic deformation. there are two ways of treating steel: 1) quenching- this is when red hot steel is rapidly cooled to R.T. this traps most of the carbon in the steel forming pearlite that makes it hard and brittle 2)Normalising- this is when red hot steel is cooled slowly to R.T and allows carbon to dislocate and form ferrite which makes it ductile. this is how mild steel is manufactured.

Allowable stress would normally refer to design using Allowable Strength Design, also known as working strength design. In this the allowable stress is usually a fraction of the yield strength and can be different for uniform tension and bending. Typically mild steel has a yield strength of about fy=250MPa with allowable stresses in Tension, 0.6fy=150MPa Bending, 0.66fy=165MPa

according to ASTM A36 Marine grade mild steel plate has a tensile strength of 58 - 80 thousand psi.
No, A36 is a mild structural steel and tool steel is a high strength alloy steel
Mild steel is of a general steel grade. HYSD stands for high yield strength deformed steel, which is of a 40 percent stronger steel grade.
it is the resistance of material to impact(sudden) loading...or..it is the impact energy absorbed per unit area.
High yeild strength deformed bars. The characteristic strength of these bars are higher than mild steel.
Specifics of their alloys, they'll have different proportions of carbon, iron, chrome etc. These changes will make the one known as steel a little stronger and harder to machine than the one called mild steel.
Mild steel is a fairly general classification and can cover a considerable variation in material properties. Cold drawn grades in particular will have a higher tensile strength than hot rolled. Something like 400 MPa for yield stress and 500 MPa for ultimate tensile strength is quite common.
