Here's a professional English product introduction for UNS S31050 (Alloy 3105):

‌UNS S31050‌ is a high-performance austenitic stainless steel specifically engineered for extreme temperature and corrosive environments. With its elevated chromium content (typically 24-26%) and balanced nickel composition (19-22%), it delivers exceptional oxidation resistance and structural stability at temperatures up to 1150°C.

‌Key Features:‌

• Superior resistance to sulfuric, phosphoric, and organic acids
• Excellent high-temperature strength and oxidation resistance
• Good weldability using common techniques (TIG/MIG) without complex post-weld heat treatment
• Maintains mechanical properties in both cryogenic and high-heat conditions

‌Primary Applications:‌
• Chemical Processing: Reactors, heat exchangers, and piping for urea production
• Oil & Gas: Catalytic cracking units and refinery equipment
• Power Generation: Superheaters and reheaters in boilers

• Aerospace: Combustion chamber components
• Nuclear Energy: Reactor internals and steam generators

Available in plates, tubes, and bars complying with ASTM standards, S31050 is particularly suited for applications where conventional stainless steels fail under thermal or chemical stress.
