347 Stainless Steel per AMS 5654
AMS 5654 is a specification for a material made of 347 stainless steel in bar, wire, forgings, rings, and tubing, all in the solution heat treated condition and certified for premium aircraft quality. Made via consumable electrode melting such as VAR or ESR, this method produces a material of exceptional purity, consistency, and fatigue strength, thus ranking as one of the best in the world for aerospace-grade 347 stainless steel.
AMS 5654 Overview
347 stainless steel in accordance with AMS 5654 has superior mechanical strength, good resistance to creep, and stable resistance to corrosion over the temperature range of 800°F to 1500°F (427°C to 816°C). Stabilization is done to prevent sensitization at high temperatures, and the consumable electrode melting process enhances cleanliness, uniform grain structure, and fracture toughness, which are key properties of critical engine parts in the aerospace industry.
The AMS 5654 material is the preferred choice when high fatigue strength and metallurgical integrity are desired in parts such as jet turbine forgings, engine rings, and exhaust parts.
What is 347 Stainless Steel ?
347 stainless steel is an austenitic stainless steel stabilized by additions of columbium (plus tantalum) and has slightly improved corrosion resistance over type 321 stainless steel in strongly oxidizing environments. It is preferable for aqueous and low-temperature environments due to its good resistance to intergranular attack. Both 347 and 321 offer good resistance to polythionic acid stress corrosion cracking, encountered in oil refineries.
