This much of explanation will be required for a proper appreciating of the subject:
Steel has a very linear stress-strain relationship up to a sharply defined yield point, For stresses below this yield strength all deformation is recoverable, and the material will relax into its initial shape when the load is removed. For stresses above the yield point, a portion of the deformation is not recoverable, and the material will not relax into its initial shape. After the yield point, steel and many other ductile metals will undergo a period of strain hardening, in which the stress increases again with increasing strain up to the ultimate strength. .
After steel has been loaded to its ultimate strength it begins to "neck" as the cross-sectional area of the specimen decreases due to plastic flow. Necking is accompanied by a region of decreasing stress with increasing strain on the stress-strain curve. After a period of necking, the material will rupture and the stored elastic energy is released as noise and heat. The stress on the material at the time of rupture is known as the breaking stress

Okay, I'm answering within a few lines --
It means Tensile Strength.(Ultimate strength is the maximum stress a material can withstand).
The term 'ultimate stress' is used to describe the maximum unit stress that a material can withstand when subjected to an applied load in a compression, tension or shear test.

What it takes to break it.
