Cov tshuaj muaj pes tsawg leeg ntawm 304 stainless hlau C ≤ 0.08 Si ≤ 1.00 Mn ≤ 2.00 P ≤ 0.05 S ≤ 0.03 Cr 18.00-20.00 Ni (nickel) 8.00 ~ 10.50 -;
Cov tshuaj muaj pes tsawg leeg ntawm 304L stainless hlau yog% C: ≤ 0.03, Si: ≤ 1.0, Mn: ≤ 2.0, Cr: 17.0 ~ 19.0, Ni: 8.0 ~ 11.0, S: ≤ 0.03, P: ≤ 0.035.
Nws tuaj yeem pom tias cov khoom tseem ceeb ntawm 304 stainless hlau thiab 304L stainless hlau yog 18% chromium (Cr) thiab 8% nickel (Ni);Qhov sib txawv tseem ceeb ntawm lawv yog 304L stainless hlau yog cov pa roj carbon tsawg 304 hlau.Feem ntau, qhov corrosion kuj ntawm 304L stainless hlau zoo ib yam li 304 stainless hlau, tab sis tom qab vuam los yog kev ntxhov siab, cov nplej ciam teb corrosion kuj ntawm 304L stainless hlau yog zoo heev.
Nyob rau hauv cov nqe lus ntawm tus nqi, 304L stainless hlau yog siab tshaj 304 stainless hlau, thiab 304L stainless hlau yog tsawg-carbon stainless hlau, feem ntau yog siv rau vuam txheej txheem.Thaum vuam, 304L stainless hlau tuaj yeem txo qhov vuam corrosion zoo.
Raws li tus qauv hardness, 304 stainless hlau zoo dua 304L stainless hlau, vim tias cov ntsiab lus carbon ncaj qha cuam tshuam rau hardness ntawm stainless hlau.Tsis tas li ntawd, muaj 304H stainless hlau series.H qhia txog cov ntsiab lus carbon siab.
Nyob rau hauv cov nqe lus ntawm daim ntawv thov, 304: 0Cr18Ni9, raws li ib tug steel nrog ib tug ntau yam ntawm daim ntaub ntawv, muaj zoo corrosion kuj, tshav kub tsis kam, tsis kub kub lub zog thiab txhua yam khoom;Stamping, dabtsi yog khoov thiab lwm yam kev ua haujlwm kub yog qhov zoo, thiab tsis muaj qhov tshwm sim ntawm kev kho cua sov (tsis yog sib nqus, siv qhov kub ntawm - 196 ℃ ~ 800 ℃).Cov khoom siv hauv tsev (Class 1 thiab 2 tableware, txee, cov kav dej hauv tsev, lub rhaub dej, boilers, da dej), qhov chaw pib (windshield wipers, mufflers, molded products), cov khoom siv kho mob, cov khoom siv hauv tsev, tshuaj, khoom noj khoom haus, kev ua liaj ua teb, thiab nkoj .
304L: 00Cr19Ni10 yog ib qho qis C 304 steel.Feem ntau, nws cov corrosion kuj zoo ib yam li ntawm 304 steel, tab sis tom qab vuam los yog kev ntxhov siab, nws cov nplej ciam teb corrosion kuj zoo heev;Nws tuaj yeem tswj tau zoo corrosion tsis muaj kev kho cua sov, thiab kev pabcuam kub yog - 196 ℃ ~ 800 ℃.
Nws yog siv rau cov tshuab sab nraum zoov hauv tshuaj lom neeg, thee thiab roj av kev lag luam nrog cov kev xav tau siab rau cov kab lis kev cai tiv thaiv corrosion, tshav kub-resistant qhov chaw ntawm lub tsev cov ntaub ntawv thiab xoom qhov chaw uas muaj teeb meem hauv kev kho cua sov.
