Dab tsi yog SUS304 stainless hlau ntawv?
SUS304 stainless hlau ntawv yog ib lub tiaj, corrosion-resistant steel uas ua tau raws li Japanese JIS cov qauv. Zoo li American AISI / SS304 steel, nws muaj 18% chromium thiab 8% npib tsib xee, muab nws zoo heev formability, durability thiab versatility. Txawm li cas los xij, vim tsis muaj molybdenum, nws cov tshuaj chloride tsis zoo li SUS316. Nws yog tsim rau cov khoom siv hauv chav ua noj, kev ua zaub mov, lub tsev facades, railings, cia tso tsheb hlau luam, khoom siv kho mob thiab kev siv dav dav.
Dab tsi yog SUS304L stainless hlau ntawv?
SUS304L stainless hlau ntawv yog cov khoom siv tiaj tiaj ua los ntawm cov pa roj carbon tsawg tsawg ntawm 304 austenitic stainless hlau. Qhov "L" qhia txog cov ntsiab lus qis dua (tsawg dua lossis sib npaug li 0.03%), uas tiv thaiv kev cuam tshuam ntawm intergranular tom qab vuam thiab tshem tawm qhov xav tau tom qab vuam annealing. Nws yog sib npaug rau AISI 304L (S30403) thiab EN 1.4306. Nws yog tsim rau welded Cheebtsam nyob rau hauv chemical cia tso tsheb hlau luam, tshav kub exchangers, piping systems thiab lub tsev cov qauv uas tsis tshua muaj siab corrosion kuj thiab post-weld structural kev ncaj ncees yuav tsum tau.
Qhov txawv ntawm SUS304 thiab SUS304L yog dab tsi?
Tsab ntawvlhauv SUS304L txhais tau tiasTsawg carbon (Low Carbon). Ob leeg yog austenitic stainless hlau raws li JIS tus qauv nrog ib tug muaj pes tsawg leeg ntawm 18% chromium thiab 8% npib tsib xee thiab zoo heev corrosion kuj. Qhov siab tshaj carbon ntsiab lus ntawm SUS304L yog0.03%, thaum cov pa SUS304 nce mus txog0.08%.
