What is A572 grade 55 ultimate strength

Posted:2020-11-05 11:44:42

As we know, A572 grade 55 is high strength steel, which is also known as HSLA steel. Then the question is coming: what is A572 grade 55 ultimate strength?

A572 grade 55 ultimate strength means the maximum stress that A572 grade 55 steel can withstand while being stretched or pulled. The A572 grade 55 ultimate strength is calculated by dividing the cross-section area of the A572 grade 55 steel tested by the stress placed on the steel. It is the final amount of stress sustained in a tensile test at the exact moment A572 grade 55 steel ruptures.

A572 grade 55 ultimate strength is also known as A572 grade 55 tensile strength. From tensile test and ASTM A572 / A572M technical standard, we can known that the A572 grade 55 tensile strength is 485 Mpa min.
