Basic qib ntawm stainless hlau

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

200 series: chromium-nickel-manganese austenitic stainless hlau
300 series: chromium-nickel austenitic stainless hlau
301: Zoo ductility, siv rau molded khoom. Kuj tseem tuaj yeem hardened los ntawm tshuab ceev. Zoo weldability. Hnav tsis kam thiab qaug zog yog zoo dua li 304 stainless hlau.
302: corrosion kuj nrog 304, vim muaj cov ntsiab lus ntawm cov pa roj carbon ntau thiab yog li lub zog zoo dua.
302B: Nws yog ib yam ntawm cov hlau tsis muaj hlau nrog cov ntsiab lus silicon siab, uas muaj kev tiv thaiv siab rau qhov kub thiab txias oxidation.
303: Los ntawm kev ntxiv me me ntawm sulfur thiab phosphorus kom nws ua haujlwm ntau dua.
303Se: Nws kuj tseem siv los ua cov khoom siv tshuab uas yuav tsum tau kub taub hau, vim tias cov hlau tsis zoo no muaj kev ua haujlwm kub kub hauv cov xwm txheej no.
304: 18/8 stainless hlau. GB qib 0Cr18Ni9. 309: kub tsis kam zoo dua 304.
304L: Ib qho txawv ntawm 304 stainless hlau nrog cov ntsiab lus qis dua, siv qhov vuam yuav tsum tau ua. Cov ntsiab lus qis dua txo qis cov nag lossis daus ntawm carbides nyob rau hauv thaj chaw uas muaj kev kub ntxhov nyob ze ntawm qhov vuam, uas tuaj yeem ua rau muaj kev cuam tshuam ntawm intergranular corrosion (weld erosion) ntawm cov hlau tsis huv hauv qee qhov chaw.
304N: Cov hlau tsis muaj hlau uas muaj nitrogen, uas yog ntxiv kom muaj zog ntawm cov hlau.
305 thiab 384: Muaj cov npib tsib xee siab, lawv muaj qhov ua haujlwm qis thiab tsim nyog rau ntau yam kev siv uas yuav tsum tau ua kom txias txias.
308: Siv los ua vuam pas nrig.
309. Thaum 30S5 thiab 310S yog qhov sib txawv ntawm 309 thiab 310 stainless hlau, qhov sib txawv yog tias cov ntsiab lus carbon tsawg dua, yog li cov carbides precipitated nyob ze ntawm qhov vuam yog tsawg. 330 stainless hlau muaj qhov tshwj xeeb siab ua haujlwm rau carburization thiab tsis kam ua rau kub poob.
316 thiab 317: muaj txhuas, thiab yog li muaj kev tiv thaiv zoo dua rau pitting corrosion hauv marine thiab tshuaj lom neeg kev lag luam ib puag ncig dua li 304 stainless hlau. Ntawm lawv, hom 316 stainless hlaulos ntawm cov variants muaj xws li tsawg-carbon stainless hlau 316L, nitrogen-muaj zog stainless hlau 316N, raws li zoo raws li cov ntsiab lus sulfur ntawm cov dawb-machining stainless hlau 316F.
321, 347 thiab 348: yog titanium, niobium ntxiv rau tantalum, niobium stabilized stainless hlau, haum rau siv nyob rau hauv kub kub nyob rau hauv lub welded Cheebtsam. 348 yog ib hom stainless hlau haum rau kev lag luam nuclear fais fab kev lag luam, tantalum thiab cov nyiaj drilling ua ke nrog qee qhov kev txwv.
400 series: ferritic thiab martensitic stainless hlau
408: Cov cua kub zoo, tsis muaj zog corrosion, 11% Cr, 8% Ni.
409: hom pheej yig tshaj plaws (British thiab Asmeskas), feem ntau yog siv los ua cov kav dej hauv tsheb, yog ferritic stainless hlau (chromium steel)
410: martensitic (high-strength chromium hlau), hnav tsis kam, tsis zoo corrosion kuj. 416: ntxiv sulfur txhim kho lub machinability ntawm cov khoom.
420: "Cutting tool grade" martensitic steel, zoo ib yam li Brinell high-chromium steel, qhov ntxov tshaj plaws stainless hlau. Kuj tseem siv rau riam phais thiab tuaj yeem ua kom ci ntsa iab.
430: Ferritic stainless hlau, kho kom zoo nkauj, piv txwv li rau tsheb accessories. Zoo formability, tab sis kub tsis kam thiab corrosion kuj yog inferior.
440: high-strength txiav ntug steel, me ntsis siab dua cov ntsiab lus carbon, tom qab kev kho cua sov tsim nyog tuaj yeem tau txais lub zog muaj zog, hardness tuaj yeem ncav cuag 58HRC, yog cov hlau tsis muaj zog. Qhov feem ntau siv piv txwv yog "razor blades". Muaj peb hom kev siv: 440A, 440B, 440C, thiab 440F (yooj yim-rau-tshuab hom).
500 Series: Kub-resistant chromium alloy hlau
600 Series: Martensitic nag lossis daus-hardening stainless hlau
630: Feem ntau siv los nag-hardening stainless hlau hom, feem ntau hu ua 17-4; 17% Cr, 4% Ni.
