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
Compressive Stress for mild steel (IS 2062 Gr.B - ASME SA 36 is 407.7 MPa This is what I think is the value. If there are different valuses please send me a amil. ramsrini16@yahoo.com Dr.S.RAmachandran, NIOT , Chennai.
66N/Sq.MM in varying condition and 100 N/Sq. MM in Steady condition for mild steel as per cmti hand book pg. 685
During a tensile test of mild steel, the bar is tested until it breaks. It measures how much stress the mild steel can take before it finally breaks under the pressure.
Mild steel tensile stress of 370 to 520 Newtons per square millimeter.
Ultimate shear stress of Mild steel is 210N/sq mm
That really depends on the type of stainless steel and how it is conditioned. For example 300 series steels that are annealed have a yield strength of 30,000 psi and a tensile strength of 80,000 psi. But if cold worked these increase to 65,000 psi and 125,000 psi, respectively, and even higher depending on method. For high strength stainless steels such as A286 or 17-4 PH, tensile strengths over 160,000 psi are realized.
Mild steel usually contains predominantly of Ferrite structure and it has got good ductility. The difference in stress-strain curve of Mild steel to other ductile materials is that it undergoes Multiple yielding. it occurs due to the fact that C and N segregate to dislocations.
The fracture toughness, or the property that describes the ability of a material containing a crack to resist fracture, of mild steel is around 50 K (where 'K' is the stress intensity factor).

mild steel is heavier
The endurance limit for steel, as a general term, flattens out at around 30ksi stress. As the cycles go to infinity, the endurance level for most steels stays above 25ksi stress.
