AMS 5629 - S13800 Aerospace Quality Steels
2024-10-14 09:23:00 Origin： Remark：0 Click：
Aerospace Quality AMS 5629 (S13800) is suitable for applications such as high tensile shafts, bolts and nuts, gears, pinions spindles and so on.
Typical Applications
Aerospace Alloy AMS 5629 (UNS S13800) has been used typically for parts requiring corrosion resistance, stress-corrosion resistance, high strength up to 600F(316C),and good ductility and strength in the transverse direction in large section sizes, but usage is not limited to such applications.
Referenced Relevant Standards
ASTM A370 Mechanical Testing of Steel Products.
ASTM A604 Macroetch Testing of Consumable Electrode Remelted Steels.
