321 Stainless Steel Wire per AMS 5689
321 Stainless Steel Wire AMS 5689 is used for 321 stainless steel wire that is known for its corrosion and heat resistance and is supplied in solution heat-treated condition. It is a titanium-stabilized austenitic chromium-nickel stainless steel that offers outstanding intergranular corrosion resistance and oxidation stability when exposed to high temperatures up to 1500°F (816°C).
Applications of AMS 5689
AMS 5689 stainless steel wire is the preferred choice when both good properties at elevated temperatures and good corrosion resistance are required.
The applications of this alloy are diverse and include the following:
– Aerospace: springs, fasteners, wiring parts, and compact high-strength structural parts.
– Industrial & Power: precision coils, heating elements, and mechanical springs for use in chemical processing.
– Marine & Offshore: corrosion-resistant wire ropes and parts that resist heat and humidity.
