446 Stainless Round Bar (Astm A276; GB 16Cr25NINI2) yog qhov siab {{chromium ferritic stainless nrog cov khoom uas outperform 430:
Lub zog tensile: 515-690 MPA, siab dua 430 tus 450-600 mpa, vim nws cov ntsiab lus chromium ntau dua (23-27% vs {{7}).
Corrosion Kuj: zoo dua rau 430 hauv qhov siab - qhov ntsuas kub oxidizing ib puag ncig (txog li 1095 degree), tawm tsam screging thiab sulphur nres.
Thaum tshav kub kub ua: tswj lub zog kub dua 430, haum rau cov chaw sov thiab hluav taws xob sib xyaw ua ke.
Ductility: 18-20% elongation, qis dua me ntsis 430 tab sis txaus rau kev tsim cov duab yooj yim.
446 yog siv nyob rau hauv cov chaw ua kom sov, fais fab nroj tshuag hlawv, thiab cov cuab yeej siv tshuaj lom neeg xav tau yam tsis muaj nqi ntau yam tsis muaj nqi
