AMS 6350 & AMS 6315

I have a gov't project and need to locat some of both. We will machine to size for later use, then heat treat to 249 KSI to strengthen. then receive items back and install.

Thank you for your help, Everett

AMS6350 is for 4130

SAE AMS6315 was canceled in 1946. The composition was aerospace quality 4340. SAE AMS6415 is the current standard:

249 ksi or BHN? 4130 isn't going to get to 249 ksi.

AMS6350 Steel Sheet, Strip, and Plate 0.95Cr 0.20Mo (0.28-0.33C) (SAE 4130) is defined within the scope section of the document:

"This specification covers an aircraft-quality, low-alloy steel in the form of sheet, strip, and plate."

This document is available at the SAE Internet site:

AMS61315 Steel 1.8Ni .25Mo (0.38 - 0.43C) Heat Treated (105,000 Tensile Strength) (Cancelled Aug 1946) has been cancelled, but can be purchased from SAE:

6315 is obsolete
6350 is an alloy steel plate spec. (4330 I think)

Sorry guys! i gave the wrong info and am giving more info.

AMS 6512 is the steel and it will be heat treated to min 240 KSI
AMS 6350 will be heat treated to min 150 KSI.

Thank you all for the info and the new site, sae.org.
