There are too many to list. For example wrought low alloy steel like 4130, or 1/2 hard stainless 301 all exceed that value
The breaking strength is always greater than the yield strength.
The yield strength is reached when the material becomes non - linear ( that is non elastic) and takes a permanent set when load is released. Material stretches but does not break. Ultimate strength is when it breaks and is higher than yield strength.
Yield strength is the most common characteristic of construction steel, it has a minimum yield strength of 275 N/mmâ_. Steel is also very tough and durable, it can withstand extremely heavy loads. It is also weldable and ductile.
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
we will measure within 2 weeks, then we'll say
The breaking strength is always greater than the yield strength.
For ductile materials, the yield stress is always lower than the tensile strength of the material. For brittle material they can usually be considered the same point. Steel is generally considered ductile.
what is characteristic yield strength
YIELD STRENGTH 242 N/sqmm TENSILE STRENGTH 440~520 N/sqmm
The yield strength is reached when the material becomes non - linear ( that is non elastic) and takes a permanent set when load is released. Material stretches but does not break. Ultimate strength is when it breaks and is higher than yield strength.
275 MPa
It is its yield stress which is equal to 235 N/mm2
yield is the breaking point and tensile strength is what it is rated at per square inch
0.5 of the yield strength.

High yeild strength deformed bars. The characteristic strength of these bars are higher than mild steel.
