AMS 5659T 15-5PH ROUND BAR

Aerospace Materials

We recently supplied to our American client- AS 9100 distributor DIA: 13'', 16'', and 30.25''round bar H1025 heat treatment according to AMS5659T standard.

U/T testing as per AMS-STD-2154 CLASS AA.

We made it!!!

Our materials undergo strict inspection for chemical composition, transverse mechanical properties, low magnification, high magnification, metallographic structure, free Fe% content, and U/T testing following AMS-STD-2154 CLASS AA standard. These have been qualified by NADCAP-certified third party.

DIA: 13'', LENGTH: 144'' (φ330MM *3658MM)

DIA: 16'', LENGTH: 144'' (φ406MM *3658MM)

 

DIA: 30.25'', LENGTH: 8.25'' (φ768MM *210MM)

AMS 5659T 15-5PH has more stringent requirements than ASTM standard materials in terms of chemical composition, mechanical property,hardness, flaw detection, Macrostructure, Microstructure, heat treatment, marking, etc.

Basic Requirements：

Third party test report

AMS 15-5PH round steel and forgings product requirements are higher than ASTM standard requirements, there are strict requirements in the entire smelting and production control process, foreign customers also attach great importance to the implementation of the contract and on-site inspection of products, and finally fully meet the requirements of AMS standard, the foreign party finally gave a high evaluation of the 15-5PH quality and quantity production and delivery. Demonstrate YuShen Steel Group's ability to deliver according to AMS standards.
