Of course, it's an alloy so it'll change depending on the ratio of the impurities.
However I notice your reply doesn't actually contain any information. What kind of steel was used in the towers? What is the strength profile of that kind of steel? How much variation is there among different grades of steel?
Those would be important questions to answer to support your position.
