Feem ntau hlau tsis xebcov qauv
Cov qauv hlau stainless feem ntau siv cov cim lej, muaj 200 series, 300 series, 400 series, lawv yog Tebchaws Meskas sawv cev, xws li 201, 202, 302, 303, 304, 316, 410, 420, 430, thiab lwm yam., Cov qauv hlau stainless hauv Suav teb siv cov cim ntsiab lus ntxiv rau cov lej, xws li 1Cr18Ni9, 0Cr18Ni9, 0Cr17, 3Cr13, 1Cr17Mn6Ni5N, thiab lwm yam., Cov lej qhia txog cov ntsiab lus sib xws. 00Cr18Ni9, 1Cr17, 3Cr13, 1Cr17Mn6Ni5N thiab lwm yam, tus lej qhia txog cov ntsiab lus sib xws.

200 series: chromium-nickel-manganese austenitic stainless hlau
300 series: chromium-nickel austenitic stainless hlau
301: Zoo ductility, siv rau cov khoom molded. Kuj tseem tuaj yeem ua kom tawv los ntawm lub tshuab ceev. Zoo weldability. Hnav tsis kam thiab qaug zog lub zog zoo dua li 304 stainless hlau.
302: tiv taus corrosion nrog 304, vim yog cov pa roj carbon ntau thiab yog li ntawd lub zog zoo dua.
302B: Nws yog ib hom hlau tsis xeb uas muaj cov ntsiab lus silicon siab, uas muaj kev tiv taus siab rau kev oxidation kub siab.
303: Los ntawm kev ntxiv me ntsis ntawm cov leej faj thiab phosphorus kom ua rau nws siv tau ntau dua.
303Se: Nws kuj tseem siv los ua cov khoom siv tshuab uas xav tau kev kub taub hau, vim tias cov hlau tsis xeb no muaj kev ua haujlwm kub zoo nyob rau hauv cov xwm txheej no.
304: 18/8 stainless hlau. GB qib 0Cr18Ni9. 309: zoo dua kub tsis kam dua li 304.
304L: Ib hom hlau tsis xeb 304 uas muaj cov pa roj carbon tsawg dua, siv rau qhov chaw xav tau vuam. Cov pa roj carbon tsawg dua txo cov carbides uas poob rau hauv thaj chaw kub ze ntawm qhov vuam, uas tuaj yeem ua rau muaj kev xeb ntawm cov hlau tsis xeb hauv qee qhov chaw.
304N: Ib hom hlau tsis xeb uas muaj nitrogen, uas ntxiv rau kom ua rau cov hlau muaj zog dua.
305 thiab 384: Muaj cov nickel ntau, lawv muaj qhov ua haujlwm tawv tsawg thiab tsim nyog rau ntau yam kev siv uas xav tau kev ua kom txias.
308: Siv los ua cov pas nrig vuam.
309, 310, 314 thiab 330: cov ntsiab lus nickel thiab chromium yog qhov siab heev, txhawm rau txhim kho qhov tsis kam oxidation ntawm cov hlau ntawm qhov kub siab thiab lub zog nkag. Thaum 30S5 thiab 310S yog cov qauv ntawm 309 thiab 310 stainless hlau, qhov sib txawv yog tias cov ntsiab lus carbon qis dua, yog li cov carbides precipitated ze ntawm qhov vuam raug txo qis. 330 stainless hlau muaj qhov tshwj xeeb tshaj yog tiv taus carburization thiab tiv taus cua sov poob siab.
316 thiab 317: muaj txhuas, thiab yog li ntawd muaj kev tiv thaiv zoo dua rau kev xeb hauv cov dej hiav txwv thiab cov tshuaj lom neeg kev lag luam dua li 304 stainless hlau. Ntawm lawv, hom 316 stainless hlaulos ntawm cov kev hloov pauv suav nrog cov hlau tsis muaj carbon tsawg 316L, cov hlau tsis muaj zog siab 316N uas muaj nitrogen, nrog rau cov ntsiab lus sulfur siab ntawm cov hlau tsis muaj zog 316F.
321, 347 thiab 348: yog titanium, niobium ntxiv rau tantalum, niobium stabilized stainless hlau, tsim nyog rau kev siv ntawm qhov kub siab hauv cov khoom welded. 348 yog ib hom stainless hlau tsim nyog rau kev lag luam fais fab nuclear, tantalum thiab qhov ntau ntawm kev khawb ua ke nrog qee qib ntawm kev txwv.
400 series: ferritic thiab martensitic stainless hlau
408: Ua kom kub zoo, tiv taus corrosion tsis muaj zog, 11% Cr, 8% Ni.
409: hom pheej yig tshaj plaws (Askiv thiab Asmeskas), feem ntau siv ua cov kav dej tso pa tawm hauv tsheb, yog ferritic stainless hlau (chromium steel)
410: martensitic (cov hlau chromium muaj zog siab), zoo hnav tsis kam, tsis zoo corrosion. 416: ntxiv sulfur txhim kho qhov machining ntawm cov khoom.
420: "Qib cuab yeej txiav" martensitic hlau, zoo ib yam li Brinell high-chromium hlau, cov hlau tsis xeb thaum ub. Kuj siv rau riam phais thiab tuaj yeem ua kom ci heev.
430: Ferritic stainless hlau, kho kom zoo nkauj, piv txwv li rau cov khoom siv hauv tsheb. Zoo formability, tab sis kub tsis kam thiab corrosion tsis kam.
440: cov hlau txiav ntug muaj zog heev, cov pa roj carbon ntau me ntsis, tom qab kev kho cua sov kom zoo, nws tuaj yeem tau txais lub zog siab, qhov nyuaj tuaj yeem ncav cuag 58HRC, yog cov hlau tsis xeb nyuaj tshaj plaws. Piv txwv li, feem ntau siv "riam txiav". Muaj peb hom siv: 440A, 440B, 440C, thiab 440F (hom yooj yim siv).
500 Series: Cov hlau chromium alloy uas tiv taus cua sov
600 Series: Martensitic precipitation-hardening stainless hlau
630: Hom hlau tsis xeb uas siv ntau tshaj plaws, feem ntau hu ua 17-4; 17% Cr, 4% Ni.
