Ferrous hlau
Ferrous hlau muaj xws li cov pa roj carbon zoo tib yam steel, siab -cov pa roj carbon zoo, hlau alloy steel, cov cuab yeej carbon steel, stainless hlau, hluav taws xob silicon steel, thiab lwm yam.
Rau cov dov steel phaj nrog lub thickness tsawg dua 4 hli, cov qauv tsim hauv lub tebchaws tau faib cov thickness precision rau hauv peb qib: A (siab precision), B (siab dua precision), thiab C (ib txwm precision).
Rau siab - zoo carbon structural txias- dov nyias cov ntawv hlau, cov qauv hauv tebchaws muaj feem cuam tshuam rau qhov zoo ntawm plaub pawg: I (ntxiv- siab- qib tiav), II (siab- qib tiav), III (siab dua- qib tiav), thiab IV (qib zoo tib yam- qib tiav). Txhua pab pawg tau muab faib ua peb qib raws li qhov muaj peev xwm kos duab: Z (ntxiv - kos duab sib sib zog nqus), S (kev kos duab sib sib zog nqus), thiab P (kev kos duab zoo ib yam).
Tsis yog- hlau hlau
Cov hlau tsis yog-ferrous muaj xws li tooj liab thiab tooj liab alloys, txhuas thiab txhuas alloys, magnesium alloys, titanium alloys, thiab lwm yam.
