Dab tsi yog stainless hlau?
Cov khoom siv stainless hlau tsis yog tsuas yog muaj nyob rau hauv peb lub neej niaj hnub, tab sis kuj tau siv dav hauv kev lag luam hnyav, kev lag luam teeb thiab kev tsim kho kev lag luam. Stainless acid-resistant steel yog hu ua stainless hlau. Nws yog tsim los ntawm stainless hlau thiab acid-resistant steel. Hauv luv luv, cov hlau uas tuaj yeem tiv taus atmospheric corrosion yog hu ua stainless hlau, thiab cov hlau uas tuaj yeem tiv taus tshuaj lom neeg corrosion yog hu ua acid-resistant steel. Feem ntau siv stainless hlau hom yog 304, 304L, 316, 316L, uas yog 300 series steels ntawm austenitic stainless hlau. 304, 304L, 316, 316L txhais li cas? Qhov tseeb, qhov no yog hais txog lubstainless hlau Standard steel qib, cov qauv ntawm cov teb chaws txawv txawv, thov mus saib cov lus hauv qab no kom paub meej.
304stainless hlau
304 stainless hlau yog ib tug universal thiab dav siv hlau nrog zoo corrosion kuj, tshav kub tsis kam, tsis kub-siab zog thiab txhua yam khoom; zoo ua hauj lwm zoo thiab siab toughness. Nws yog dav siv los ua cov cuab yeej thiab qhov chaw uas xav tau kev ua haujlwm zoo (corrosion resistance and formability). Nws yog resistant rau corrosion nyob rau hauv cov huab cua. Yog tias nws yog ib qho chaw ua lag luam lossis thaj chaw muaj kuab paug hnyav, nws yuav tsum tau muab ntxuav kom huv si kom tsis txhob muaj corrosion. Nws yog resistant rau corrosion nyob rau hauv cov huab cua. Yog tias nws yog ib qho chaw ua lag luam lossis thaj chaw muaj kuab paug hnyav, nws yuav tsum tau muab ntxuav kom huv si kom tsis txhob muaj corrosion. 304 stainless hlau yog lub teb chaws lees paub zaub mov-qib stainless hlau.
316stainless hlau
Qhov sib txawv tseem ceeb ntawm 316 thiab 304 hauv tshuaj muaj pes tsawg leeg yog tias 316 muaj Mo, thiab nws feem ntau lees paub tias 316 muaj kev tiv thaiv corrosion zoo dua thiab tiv taus corrosion nyob rau hauv qhov chaw kub kub tshaj 304. Nws tuaj yeem siv nyob rau hauv qhov hnyav hnyav. tej yam kev mob; kev ua haujlwm zoo hardening (tsis muaj zog lossis tsis muaj hlau nplaum tom qab ua tiav); non-magnetic nyob rau hauv lub xeev cov kua; zoo welding kev ua tau zoo. Kev siv ntau yam, xws li tshuaj lom neeg, tshuaj zawv plaub hau, ntawv, oxalic acid, chiv thiab lwm yam khoom siv ntau lawm, kev lag luam khoom noj khoom haus, cov chaw hauv thaj chaw ntug dej hiav txwv, tshwj xeeb raustainless hlau limlwm.
"L"
Raws li peb txhua tus paub, Stainless hlau muaj ntau yam ntsiab lus, thiab cov hlau uas muaj cov ntsiab lus carbide txo qis dua li cov ntsiab lus dav dav yuav raug qhia los ntawm kev ntxiv "L" tom qab qib-xws li 316L, 304L.Vim li cas peb yuav tsum txo cov carbides? Feem ntau los tiv thaiv "intergranular corrosion". Intergranular corrosion, nag lossis daus ntawm carbides thaum lub sij hawm kub kub vuam ntawm hlau, rhuav tshem cov kev sib raug zoo ntawm cov pob zeb siv lead ua, zoo heev txo cov neeg kho tshuab lub zog ntawm cov hlau. Thiab cov hlau saum npoo feem ntau tseem nyob ruaj khov, tab sis tsis tuaj yeem tiv thaiv lub khob, yog li nws yog qhov txaus ntshai heev corrosion.
304l uastainless hlau
Raws li cov pa roj carbon tsawg 304 steel, nws cov corrosion kuj zoo ib yam li ntawm 304 steel nyob rau hauv ib txwm muaj, tab sis tom qab vuam los yog kev ntxhov siab nyem, nws tsis kam mus rau intergranular corrosion yog zoo heev. Nws tuaj yeem tswj tau zoo corrosion tsis muaj kev kho cua sov thiab tuaj yeem siv ntawm -196 ℃ ~ 800 ℃.
316l uastainless hlau
Raws li cov pa roj carbon tsawg ntawm 316 steel, ntxiv rau cov yam ntxwv zoo ib yam li 316 steel, nws muaj kev cuam tshuam zoo intergranular corrosion. Nws tuaj yeem siv rau cov khoom lag luam nrog cov kev xav tau siab rau kev tiv thaiv intergranular corrosion, nrog rau cov tshuab sab nraum zoov hauv cov tshuaj, thee, thiab roj av industries, tshuaj nroj tsuag thiab lwm yam kev lag luam. Ntau dua susceptibility rau intergranular corrosion tsis txhais hais tias cov ntaub ntawv uas tsis yog-tsawg carbon yog ntau raug rau corrosion. Nyob rau hauv ib puag ncig high-chlorine, qhov rhiab heev no kuj siab dua. Cov ntsiab lus Mo ntawm 316L ua rau cov hlau muaj kev tiv thaiv zoo rau pitting corrosion thiab tuaj yeem siv nyab xeeb hauv ib puag ncig uas muaj halogen ions xws li Cl-.
HENGKO stainless hlau lim caij ua los ntawm 316 thiab 316L, nws muaj qhov zoo ntawm qhov kub thiab txias tsis kam, zoo corrosion kuj, siab zog, thiab nruj zoo soj ntsuam txuas los xyuas kom meej tias qhov zoo ntawm cov khoom tawm ntawm lub Hoobkas dhau cov kev lis kev cai.
Ntawm no yog kev sib piv ntawm qhov sib txawv ntawm cov khoom thiab cov yam ntxwv ntawm stainless hlau hom 304, 304L, 316, thiab 316L:
