Overview

This chromium-nickel-molybdenum alloy, “king” of the hardening grades of alloy steels, possesses much deeper hardenability than the 4100 series. The fatigue-tensile ratio makes it ideal for highly stressed parts such as landing gear legs, and is often referred to as “spring steel”. Tensile strength is about 110,000 PSI. It is difficult to weld but can be welded by any of the common welding processes providing the section is preheated and stress relieved after welding.

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.

Q: Checking out the 4340 steel, looking at the page showing rectangular flat, it has ONLY 2 dimensions, length and width? What are the thicknesses?

The listing was thickness x width. We have updated the chart to seperate these columns to be more clear. This material is priced and sold by the foot.
