304L Sinles Sil
304L em i wanpela low-} kabon austenitis steinles stiel ol i save long gutpela korosen resistens bilong en, gutpela masin, na weldim. Wetem wan kabon konten we i stap anda long 0.03%, hem i daonem bigwan risk blong sensitisasen mo intagranular korosen, mekem se i stret gud blong ol aplikesen we post{4}weld hit tritmen i no posibol.

Samting
Dispela samting i soim stebol pefomens long tupela oksidaising na i no strong long daunim midia, na soim resistens long naitrik asid, ol ogen asid, na ol alkaline solusen, wantaim ol moderet klorait stres korosen resistens long rum tempereja.
304L i ofaim bikpela daktiliti na strong (elongasen Bikpela long o wankain olsem 40%), i ken kamap strong long kol wok, na em i no-magnetik long annealed stet (i ken kisim liklik magnetism bihain long kol defomesen). Em i gat bikpela opereting tempereja mak (-196 digri i go long 800 digri ), na dispela i mekim em i ken mekim kain kain wok bilong ol kain kain indastri aplikesen.
