what is the tensile strength of steel?

Question

In pounds per square inch what is the tensile strength of strong steel?

Answer 1

Depends on what you mean by "strong" steel. Typically the ultimate strength/yield point of steel used for building structures (beams, columns, joists, plates) is in the range of 36,000 to 50,000 psi. The strength is specified by the designer (in the U.S.) by its ASTM designation. e.g. ASTM A36, A572, A500, A307, A325 ...



A36 is typical "mild steel", A572 Grade 50 (50,000 psi) is often called "high-strength"



Really high strength steels such as pre-stressing strand can have ultimate strengths more than 10 times these values.

Answer 2

The term tensile strength refers to the amount of tensile (stretching) stress a material can withstand before breaking or failing. The ultimate tensile strength of a material is calculated by dividing the area of the material tested (the cross section) by the stress placed on the material, generally expressed in terms of pounds or tons per square inch of material. Tensile strength is an important measure of a material's ability to perform in an application, and the measurement is widely used when describing the properties of metals and alloys.

Answer 3

It is refereed to the ultimate tensile strength which is the point at which the specimen of steel fail (rapture) when subjected to a force,measured by unit force divided by cross section of steel.

Answer 4

I have included a link to a web site that lists material properties. If you know the name of the steel type it in and it will tell you.



Some common steels:

1030 steel 50,000 psi yield strength

304 stainless steel 31,200 psi yield strength



The strongest that was listed (quick search) on matweb was

132,000 psi yield strength. 1340 Steel, oil quenched from 830°C (1525°F), 540°C (1000°F) temper http://www.matweb.com/search/SpecificMaterial.asp?bassnum=M134AF











Good Luck!

Answer 5

it depends on the type of steel



0.6Fy*Ag less than or equal to 0.5FuAe



Fy = steel yield stress (50 ksi these days)

Ag is gross cross sectional area of member under tension



Fu = steel ultimate stress (58 ksi)

Ae = effect area of member under tension; depends on end conditions, holes, etc.
