AISI 4140 steel costing

05/24/2007 8:32 AM

Greetings,

I am working on a senior project for my Industrial Technology degree through Southern Illinois University - Carbondale's weekend program. I am a working professional with 25+ years of manufacturing/machining experience, finishing my degree after many years. I have previously contacted several steel vendors, to no avail, requesting pricing information for bar-stock.

What I am trying to find out is a realistic cost for a 12' bar of AISI 4140 (annealed) steel in a few sizes so that I can more accurately judge costs. Even a price per pound would be good. My first year annual usage of various sizes is about 400 bars each. I can make up "fictitious" price breaks as my quantities go up. I jokingly told my professor I should invest in a steel mill by year ten. I need information for any of the following sizes: 1" round, 1-1/8" round, 1" square, and 1/2" x 1-1/4" square.

Any advice on how to figure price breaks over buying say 200 bars vs. a mill run and how much a quantity mill run would be.

Any information I could get for solid scrap value would also be quite helpful.

Best Regards,

David Cook

Contact Ryerson (www.ryerson.com). There are many other distributors and processors from whom you can obtain cost data. Ryerson is probably the largest in North America with several locations including one near you.

Check out globalspec for others.

Hi David,

Your quantities are too low for a mill run, so you are stuck with service center pricing. They will mark it up quite bit as a general practice- thats their buisiness model- and you will need to find one that will sell "retail" for a student project. I am sending to you separately the contact information for Lapham Hickey Steel and Corey Steel who are located in Chicago. The price breaks for most service centers will be at one, two, five, ten ton and truckload levels PER ITEM. surcharges are applicable and applied by mills over and above the actuial sales price of the steel, so make sure that you understand the quote- does it or does it not include surcharge?

Don't forget freight.

12 foot 1" rd bar is 2.2670 lb/s ft so each bar weighs 27.20 pounds, 200 of these is 5440 pounds

Factor for 1-1/8" rd is 3.380lb/ft;

1" sq is 3.4 lb/ft;

1/2" sq is .8500 lb/ft;

1-1/4" sq is 5.313 lb/ft

A discussion of raw materials and pricing can be found here:

The time to have purchased steel stocks was two to three years ago.

Now is the time to buy another unloved sector that is trying to rebound.

Health care has demographics to give it the nod, telecom is another.

I'm not sure I'd buy into steel at the top of the market.

Just for follow up. I was able to get some pricing information from Ryerson, a very helpful fellow indeed. In quantities of 25K pounds average price would be $8.31 @ pound. Mill run would constitute 85K pounds and price break would be about 8% for break unit quantity purchased as spot buy and delivered in one shipment for the first two mill runs the price break drops off on a sliding scale after that down to more like 1.5%. Thanks again for your input.

check the 4140 steel bar data sheet, and otai steel is a better choice for you in such engineering steel.
