Mills Go Back to Work: Output Hits a Seven-Week High as Nucor Adds $10

Last week this space covered the quietest market in months — flat prices, flat scrap, utilization sliding to a three-month low. One week later the production line moved first, and it moved hard.

Output reversed

American mills produced 1,858,000 short tons in the week ending July 25, up 28,000 tons — 1.5% — from the prior week, according to AISI data reported by Steel Market Update. Capability utilization climbed to 80.5%, up from 79.3% the week before and 78.2% a year ago.

That is a seven-week high, and it puts output 4.9% above the same week in 2025 and 2.0% above the year-to-date weekly average of 1,821,000 tons. A week ago the story was mills easing off. That reversed in a single reporting period.

Nucor moved with it

On Monday, July 27, Nucor set its consumer spot price for hot-rolled coil at $1,145 per short ton, up $10 from the prior week. On the West Coast, CSI’s price went to $1,200/ton, a $15 jump. Lead times held at three to five weeks, per the company’s letter to customers.

Three to five weeks is the number worth noting. Mills raising price while lead times stay short are betting on demand rather than reacting to a backlog.

Scrap still hasn’t moved

Here is the part that matters to anyone feeding a shredder. Ferrous scrap did not follow. Across the week, #1 HMS, shredded auto scrap, HMS 80/20 and #1 busheling all traded flat — no week-on-week movement in any major grade. The cited reasons were adequate scrap availability and disciplined mill buying.

So mills are running harder and charging more, while the raw material going into the furnace costs what it cost last month. That spread is widening in the mills’ favor.

The output number is the leading indicator

If you sell scrap, the price print tells you where you’ve been. Utilization tells you where you’re going. Mills at 80.5% and climbing are consuming more feed than mills at 79.3%, and sustained higher consumption against “adequate” supply is what eventually pulls scrap off a flat line.

It hasn’t happened yet. One week is not a trend, and disciplined buying can absorb a lot of extra output before anyone raises a bid. But the sequence — output up, finished price up, scrap flat — is the setup that precedes a scrap move, not the one that follows it.

What this means for your pins

A busier mill sector means busier shredders, and busier shredders wear out hammer pins faster. That is straightforward.

The less obvious part is timing. Steel input costs for wear parts move with the finished market, not with scrap. Hot-rolled coil at $1,145 and climbing signals where alloy bar pricing is heading over the next quarter, even though the scrap you’re selling hasn’t moved a dollar. If you are budgeting pin replacements on the assumption that flat scrap means flat costs, that assumption is drifting.

Two things worth doing while the spread is wide. Know your actual cost per ton shredded, including wear parts — not a per-pin price, but what a set of pins costs you across the tons it survives. And place reorders on your own schedule rather than at the point of failure. An unplanned changeout during a run costs far more in downtime than the pins ever did, and that arithmetic gets worse in exactly the weeks when mills are running hardest and everyone wants delivery at once.

Domestic steel helps here too. When the market tightens, lead times on imported bar stretch first.
