304L Austenitic Stainless Steel - Tsawg-Carbon Weld-Rov qab Corrosion Solution

Kev piav qhia

304L yog qhov qis-carbon variant ntawm 304, tshwj xeeb yog tsim los tshem tawm cov kev cuam tshuam ntawm intergranular (sensitization) hauv welded Cheebtsam. Nrog rau cov ntsiab lus siab tshaj plaws ntawm 0.03%, nws tiv thaiv kev tsim ntawm chromium carbides nyob rau hauv tshav kub- cuam tshuam cheeb tsam thaum vuam, tshem tawm qhov xav tau rau kev tshaj tawm -weld annealing-ib qho tseem ceeb kom zoo dua rau cov qauv welded loj lossis nyuaj. Nws khaws cia tib yam 18-8 chromium{15}}nickel muaj pes tsawg leeg li 304, xa zoo tib yam corrosion kuj thiab formability, thaum muab kev txhim kho ductility thiab weld kev ncaj ncees. Tsis zoo li tus qauv 304, 304L yog qhov kev xaiv rau hnyav-section fabrications, chemical processing equipment, and piping systems where post-weld corrosion stability is non-negotiable, provides a trustable, cost-efficient solution for welded applications.
