Overview

4130 STEEL SHEETS
AMS-6345* NORMALIZED
*Formerly MIL-S-18729C

This chromium-molybdenum alloy is one of the most widely used aircraft steels because of its combination of weldability, ease of fabrication and mild hardenability. It will respond to heat treatment to high strength levels and yet, in the annealed condition, it has adequate strength for many applications. Used for the manufacture of parts and components. 4130 Steel Strips may be ordered in full lengths (6 ft.) or in 1/2 lengths (3 ft.). Please note that it is cheaper to ship 3 ft. lengths as full lengths are subject to UPS oversize charges. 1/2 lengths my be ordered by using .5 as a quantity. Full lengths may be ordered and we will cut in half at no extra charge if cutting is specified at time of order. PN 03-20000 have a slight curve due to shearing.

If Mfg. Test Reports are required, there's a minimum $15.00 charge per order. Please indicate P/N 01-01133 in the Special Instructions Box during the checkout process.

Good steel for being bent with a hammer and used for a crankshaft scraper in the oil pan

I needed high strength, thin steel strip for a lightweight base for a portable lighting system. this does the trick. I cut & form it and have it powder coated. Works & looks great. Price is fair & it is shipped quickly & packaged well for shipment. Well buy more!

Nice flat piece of stock welds clean easy to work with

So far so good, welds nicely and is stiff enough for my use. Only complaint is that you only have the choice of 3 or 6 lengths, for me 5 is better and ships without additional charges. That said, I have to say shipping is very reasonable compared to other online metal suppliers.

There were variations of up to an 1/8 in the width of the materials. One was over 1 1/8 wide. Other than that it was OK

Q: Can you please confirm if the price is per 6ft length, not per foot?

The price is for 6 ft lengths. To order 3 ft lengths, use quantity 0.5.

Q: Re: Item 03-19800 (.125 thick 1-1/2 wide). Are 10 foot lengths available?

No. 6 foot is the max length.

Q: Is there any info on the ultimate tensile strength for the 4130 strips? Is it annealed?

Tensile strength varies by size and lot. Certified test reports with tensile strength information are available upon request at time of order. Yes, it is annealed.

Q: Are the 4130 steel strips hot roll or cold roll?

This will be cold rolled.
