ASTM A182-F44 Forged Shafts (UNS S31254, 1.4547, 254SMO)
We are a professional manufacturer of ASTM A182-F44 Forged Shafts (UNS S31254, 1.4547, 254SMO) in China.
ASTM A182-F44 Forged Shafts
A forged shaft is a high-strength, durable component used in various industries, including automotive, aerospace, power generation, and heavy machinery. It is produced through the forging process, which involves heating metal and shaping it under high pressure to refine its grain structure, enhance mechanical properties, and improve resistance to fatigue and impact.
ASTM A182 F44 Forged Shaft – Super Austenitic Stainless Steel (UNS S31254)
ASTM A182 F44 is a super austenitic stainless steel with exceptional corrosion resistance, high strength, and excellent mechanical properties. It is widely used in marine, offshore, chemical, and desalination industries, where resistance to chloride-induced corrosion and high mechanical strength are required.
Features of ASTM A182 F44 Forged Shaft:
Superior Corrosion Resistance – Excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking (SCC).
High Strength & Toughness – Stronger than 316L and 904L stainless steel.
Good Weldability & Machinability – Suitable for precision machining and fabrication.
Excellent Performance in Harsh Environments – Used in seawater applications, high chloride environments, and aggressive chemical processing.
