Can the Yield strength of steel ever be greater than the Ultimate tensile 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.

∙ 14y agoThe ratio of the actual Ultimate Tensile Strength to the actual Yield strenght must not be less than 1.25 ratio to impart ductility
1. This is a tricky question. In a practical and real sense, yield strength can never exceed ultimate strength. Because at ultimate strength the materrial continuum of steel fractures whereas at yield strength it elongates plastically. However, I feel one cannot rule out the possibility of a change in constitution of steel during elongation, leading to a revaluation of ultimate strength. In the present state of technology, yield strength cannot exceed the ultimate strength

What is the yield strength of plain concrete?
The yield strength in this case is equal to the ultimate tensile strength, which is about 0.9-3 MPa without any reinforcement.
When a tensile strength test specimen begins to deform permanently it has reached its?
Tensile yield point or yield strength
What happened to the ultimate tensile and yield strength of most of the metals when temp falls?
building will collapse due to steel failure
What is the tensile strength of A36?
54,000 psi is its ultimate breaking tensile strength. Yield point is 36,000 psi
How would you describe a metal that has a yield strength and tensile strength that are the same?
Brittle
What is the yield strength of plywood?

What is the difference between yield strength and tensile strength?
Yield strength is a form of tensile strength, as yield strength is maximum strength upto which a material retains its original shape or it is in elastisity above which it will in plasticity.
Can metric grade 12.9 be worst than 10.9. i.e. more brittle?
The "metric grade" your asking about conforms to North American metric standards. The 12.9 should have a ultimate tensile strength of 1200 MPa and tensile yield strength of 1080 MPa. The 10.9 should be weaker have a ultimate tensile strength of 1000 MPa and tensile yield strength of 900 MPa. You are asking "can" it be more brittle. It should not be but it can be if a problem with manufacturer quality control.

What happened to the ultimate tensile and yield strength of most of the metals when temp falls?
building will collapse due to steel failure
Is there a general rule for yield vs tensile strength in steel?
yield is the breaking point and tensile strength is what it is rated at per square inch
What is the tensile strength of A36?
54,000 psi is its ultimate breaking tensile strength. Yield point is 36,000 psi
What is yield stress value for frp?
3000 MPa ultimate tensile strength (more than 10 times mild steel)
What is the ultimate yield strength of astm 1018 steel?
ASTM 1011 comes in many grades which determine the yield strength ie:1011 gr 42 would have a min yield of 42,000 psi
