The world has too much steel (NY tTimes article)

Theis article is about the overproduction of steel products world wide.

Nowadays, a lot for countries sustainoperate their own local steel mills, because of national securitiesy reasons.

Steel can be used in many ways, like for building cars, bridges and all kinds of civil commoditiessuch as for manufacturing cars and building infrastructure.

But it'It’s also used for building tanks, aircrafts and bombs.

Therefore, no nations wants to give up their own steel productions.

The result of the overproduction of steel products areis, falling prices, cutoffs of employiesemployee layoffs, and shrinking companiesy revenues.

On top of that, imposed the US aAmerican president -, Donald Trump - new import penalties for, has imposed a new import tax on non-US steel products.

But not only is the US triesying to protect their markets from foreign -competitors, and mostre importantly, cheaper steel -prices also die EU imposed import penalties for chinese steel aswell.

I don’t understand this part, “… also die EU imposed import penalties for Chinese steel as well.”

New enviormental regulations are forcesing more and more companies to go forimplement green(er) ways tof manufacturing steel.

But the problem is, manufacturing methods withat less envioronment intense manufactoring methods - likeal impact, such as melting iron ore with electricity -, increases the prices for of steel products.

Btw: There is one detail that is not explained in the article, but it's important to know.

As soon as the melting process has startetd, you cannot turnout the furnace or lower the outcome.

I don’t understand, “…you cannot turnout (turnoff ? ) the furnace or lower the outcome (temperature ? )

So you must keep going, because otherwise the furnace get's destroyed and needs to be rebuild completly t from scratch as soon as the fire turns out.

I don’t understand, “…as the fire goes out (the furnace is turned off ? )”

The world has too much steel (NY tTimes article)

"NY Times" is the name of a newspaper and should be properly capitalised.

The article is about the overproduction of steel products world wide.

"Worldwide" is one word.

Nowadays a lot ofor countries sustairun their own local steel mills, because of national securitiesy reasons.

"Run" might be a more appropriate word to use with "steel mills".

Steel can be used infor many waythings, like for building cars, bridges and all kinds of civilurban commodities.

"In many ways" might be acceptable, but I think "for many things" is more appropriate in this context.

Therefore, no nations wants to give up their own steel productions.

(1) In this context, the noun that follows "no" is singular: "no one", "no person", etc.
(2) "Production" is generally an uncountable noun.

The result of the overproduction of steel products areis falling prices, cutoffs of employieemployee layoffs and shrinking companiesy revenues.

(1) "Result" is singular, so you should use "is" and not "are".
(2) The word you're looking for is "layoff", not "cutoff".

On top of that, imposed the US aAmerican president - Donald Trump - new import penalties forhas imposed tariffs on non-US steel products.

(1) "US American" is redundant. You only need to use one of them.
(2) "American" is the name of a nationality, so it's a proper noun and should be capitalised.
(3) Em dashes are unnecessary here.
(4) We have a more technical word for "import penalty": "tariff".

But not only the US triesthe US is not the only one trying to protect their markets from foreign - and most importantly, cheaper - steel - also die EU; the EU has also imposed importtrade penalties for con Chinese steel aswell.

(1) Rewrote some parts of your sentence to make it more natural and fluent.
(2) "Important" is an adjective. The adverb which you should use here is "importantly".
(3) Note the placement of the second em dash.
(4) The "as well" at end is redundant, because you've already use "also".

New envioronmental regulations are forcesing more and more companies to go for green(er) ways tof manufacturing steel.

But the problem is, that less envioronment intenseally damaging manufactouring methods - like melting iron ore with electricity - increases the prices ofor steel products.

(1) Alternatively, instead of "less environmentally damaging", you can use "more environmentally friendly".
(2) "Methods" is plural, so you should use "increase" and not "increases".

Rising prices causes less demand and more overproductiongreater surplus, because potential buyers will wait until the marktet prices are falling.

(1) "Prices" is plural, so you should use "cause" and not "causes".
(2) The more correct term to use is "surplus".

Btw: T, there is one detail that is not explained in the article, but it's important to know.

Of course, in formal writing, do spell "btw" out in full: "by the way".

As soon as the melting process has startetd, you cannot turnout off the furnace or lower the outcomeput.

So you must keep going, because otherwise the furnace get's destroyed and needs to be rebuildt completely from scratch as soon as the fire turngoes out.

Mind the tense. The past tense of "rebuild" is "rebuilt".
