303 steel steel waa "18-8" chromium-nickel ahama bir ah oo lagu beddelay ku darida selenium ama baaruud, iyo sidoo kale fosfooraska, si loo hagaajiyo mashiinnada iyo guryaha aan la qabsan karin. Waa tan ugu diyaarsan ee lagu farsamayn karo dhammaan darajooyinka aan lahayn chromium-nickel waxayna leedahay iska caabin daxaleed oo wanaagsan, in kasta oo uu ka yar yahay darajooyinka kale ee chromium-nickel (304/316). Ma aha birlab la'aan marka la eego xaaladda la jeexjeexay oo aan lagu adkeyn daawaynta kulaylka.
Guryaha
303 waxaa sida caadiga ah loo soo iibsadaa si loo buuxiyo shuruudaha kimistariga ee aan ahayn shuruudaha jireed. Sababtaas awgeed, guryaha jirka guud ahaan lama bixiyo ilaa la codsado ka hor wax soo saarka. Wax kasta ayaa loo diri karaa qolo saddexaad ka dib wax soo saarka si loogu tijaabiyo sifooyinka jireed.
