Rhagymadrodd

Mae stribed dur di-staen 304L yn ddur di-staen cyfres 300 sy'n un o'r stribedi metel a ddefnyddir fwyaf eang oherwydd ei wrthwynebiad cyrydiad a gwneuthuriad braf.

Gellir defnyddio stribedi dur di-staen 304 a 304L ar gyfer llawer o gymwysiadau tebyg ac mae'r gwahaniaethau'n fach, ond maent yn bodoli mewn gwirionedd.

Mae gan stribed dur di-staen 304L gynnwys carbon is na 304 o stribedi dur di-staen.

Cais

Defnyddir stribed dur di-staen 304L yn eang mewn strwythurau modurol, diwydiant cemegol, diwydiant prosesu bwyd, diwydiant amgylchedd morol, ffynhonnau, rhannau weldio a diwydiant cyfnewidwyr gwres.

Gellir defnyddio stribed dur di-staen 304L hefyd mewn cymwysiadau diwydiannol trwm, yn enwedig mewn amgylcheddau cyrydiad uchel.
