AISI 4130 (E4130) per AMS 6348 - Bars

Aircraft Quality 4130 per 6348 / S6758 Cold Finished Round Bar

4130 steel bars are a chromaloy (Chrome and Moly rich) aircraft quality alloy metal. Ideal for general use when welding and moderate tensile properties are required. Our 4130 Alloy Steel carries the term "Aircraft Quality" (AQ) which means it is generally acceptable for use in aircraft parts, but still subject to magnetic particle inspection after machining.

If you don't see the size below for your 4130 material, call your salesperson as our inventory is constantly changing and new items may not be listed below. Or request a quote online now for alloy steel 4130 sheet using our convenient form.
