Was necessary. China produces 10x as much steel as US. What if war breaks out?
Matter of national security, geopolitics …to prevent war, peace trough strength.

+ deliberate performance issues to impact military / infrastructure.
We were sold out.
You have so much more than you know.

I’m thinking this may also relate to the other Q mentions of “bridge”
THE MYSTERY OF THE BRAND-NEW BAY BRIDGE’S CORRODED STEEL
https://www.wired.com/2015/06/mystery-brand-new-bay-bridges-corroded-steel/
Plink goes the pendulum arm as it smashes into a 3-inch section of steel. The sound is high-pitched, which tells any metallurgist with a good ear that the piece is brittle. The arm is the business end of a Charpy impact tester—it swings into a thing and, on impact, measures how much energy it took to break that thing. In this case, the thing is steel from a new bridge connecting two cities in one of the most seismically active places on the planet. And the steel broke. The flat, glittery inner surfaces show that in its short time holding together the new Bay Bridge, the steel corroded.
Bridge Comes to San Francisco With a Made-in-China Label

SHANGHAI — Talk about outsourcing.
At a sprawling manufacturing complex here, hundreds of Chinese laborers are now completing work on the San Francisco-Oakland Bay Bridge.
Next month, the last four of more than two dozen giant steel modules — each with a roadbed segment about half the size of a football field — will be loaded onto a huge ship and transported 6,500 miles to Oakland. There, they will be assembled to fit into the eastern span of the new Bay Bridge.
The project is part of China’s continual move up the global economic value chain — from cheap toys to Apple iPads to commercial jetliners — as it aims to become the world’s civil engineer.
Look At All The Major Chinese Bridges That Have Collapsed In The Recent Years

Earlier this month, a bridge in Harbin city that cost 1 billion yuan to make collapsed killing 3 people.
But as many as six bridges have collapsed across China since July 2011, and most have been attributed to poor construction and overloading, according to The Telegraph.
A Charpy specimen doesn't always break. If one was exploring the ductile-to-brittle transition temperature, then testing at a temperature above that level might produce a result in which the specimen didn't break. If that happens, then one would have to increase the energy to fracture the specimen.Corrosion resistance is generally off in a diffrent direction from impact resistance.
Not to say the steel isn't crap, but the article does a crappy job of cause and effect analysis.
