Metal commodities have flattened somewhat, and it is hard to say what will happen with iron since the Chinese now export steel (much to the irritation of the Euros from the sounds of it).
Unlike oil and a few specialty metals, there is plenty of metal ore in the world. The constraint is mining/production, and historically if the price is high enough someone will fill the demand and the price goes down. Lead times are very long, and in decades past mining companies have lost quite a bit of money expanding fast and glutting the market-- witness the copper glut 10-15 years ago. So, they tend to expand more methodically now.
The wild card here, is the dropping US dollar. If the Chinese continue to loosely peg to the dollar, the lid will hold on prices to some extent. If the Chinese unpeg, "buy now or pay much more later" may be a good mantra. The Euro and Loonie being up puts significant pressure on items with those foreign contents, NH and MF come to mind.
I was never able to figure out a rational reason why the politicians advocated a recession by a quick unpeg of the Chinese yuan (unless, of course, they were on the payola of the speculators who would make a windfall profit. The rest of us just get financially incinerated).
The large American content of the PT might help them hold the line a bit better than other mfg with more foreign content. Generally machinery and construction materials companies push the prices up in January/February, so if you are looking at 1Q or 2Q purchase, sometimes it's cheaper to buy in 4Q (depends on your particular circumstances/carrying costs).
Gee, I'd really like to have a PT1850 under the Christmas tree
