Q275 steel phaj

Q275 steel phaj yog ib hom carbon structural steel, siab zog, zoo plasticity thiab txiav kev ua tau zoo, vuam kev ua tau zoo, cov khoom me me tuaj yeem quenched thiab ntxiv dag zog, feem ntau yog siv los tsim cov khoom nrog cov kev xav tau siab, xws li lub zog thiab shafts. , sprockets, yuam sij, bolts, ceev, seem steels rau kev ua liaj ua teb machinery, conveyor chains thiab txuas.

Q275 steel phaj sib npaug cov khoom: sib xws rau Japanese JIS hom: SS490
International Organization for Standardization:
E275A
Ua raws li lub npe qub: A5

Chemical muaj pes tsawg leeg (feem seem) ntawm Q275 steel phaj (%)
