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.
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
66N/Sq.MM in varying condition and 100 N/Sq. MM in Steady condition for mild steel as per cmti hand book pg. 685
Fy = 235Mpa Fu = 400Mpa
Ultimate shear stress of Mild steel is 210N/sq mm
A factor of safety against yield is applied to design stress Yield Stress/ Design Stress = Factor of safety The factor of safety varies for different industries; 1.5 is used in structural steel design for buildings; 1.25 or even 1.1 for aircraft/space systems

Mild steel tensile stress of 370 to 520 Newtons per square millimeter.
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.
Fy = 235Mpa Fu = 400Mpa
Ultimate shear stress of Mild steel is 210N/sq mm
ultimate stress=Factor of safety*Allowable stress
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.
