Cov nta ntawm stainless hlau huv yeeb nkab

Date:May 11, 2019

Feem ntau ntawm cov hlau tsis huv cov yeeb nkab tu khoom yog ua los ntawm cov khoom zoo txawv teb 304 stainless hlau los xyuas kom meej tias cov kav dej muaj kev huv si thiab tsis muaj kuab lom, thiab ua raws li lub teb chaws GB / T17219-2001 "Kev Tshuaj Ntsuam Xyuas Kev Nyab Xeeb Tus Qauv rau Cov Khoom Siv Dej Ntim" thiab CJ / T151-2001 "Nyias-walled stainless hlau dej kav dej" cov qauv ntsuas tseem ceeb. Mas siv hauv kev tso dej thiab pov tseg, dej kub, dej txias, cua sov, dej haus.



Raws li cov khoom siv dav siv hlau, 304 stainless hlau huv yeeb nkab tau zoo corrosion tsis kam, tshav kub tsis kam, tsis tshua muaj kub muaj zog thiab cov cuab yeej muaj zog; stamping, khoov, ua haujlwm kub, tsis muaj kev kho cua sov ua rau muaj qhov tshwm sim (tsis yog hlau nplaum, siv kub -196 ° C ~ 800 ° C). Cov kav dej no tuaj yeem siv rau cov khoom siv hauv tsev (1, 2 hom khoom siv hauv rooj tog, tub rau khoom, khoom siv sab hauv tsev, dej rhaub dej, rhaub dej, dab da dej), qhov pib ntawm tus kheej (cua tshuab khaub ncaws, mufflers, mouldlers khoom), cov cuab yeej siv kho mob, cov ntaub ntawv hauv tsev, tshuaj lom neeg, khoom noj kev lag luam, kev ua liaj ua teb, chaw nres nkoj.



304L stainless hlau huv yeeb nkab belongs rau qis carbon austenitic stainless hlau thiab acid resistant steel. Nws muaj dav dav anti-intergranular corrosion tsis kam, zoo heev corrosion tsis kam thiab txias ua hauj lwm stamping. Nws muaj zog muaj zog tiv taus oxidizing acid (xws li nitric acid). Cov kev daws teeb meem alkaline thiab feem ntau cov organic thiab inorganic acids kuj muaj qee qhov kev txhim kho corrosion. Cov hlau no tsim nyog rau kev tsim cov khoom sib sib zog nqus, nrog rau cov kav dej tso kua mis, cov kua qaub ua kua, thiab lwm yam 304H muaj qhov zoo corrosion thiab weldability, thiab nws lub zog thermal zoo.
