Chromium yog tus thawj coj tus neeg sawv cev rau kev sib tham corrosion tsis kam nyob hauv nruab nrab nruab nrab lossis oxidizing ib puag ncig.

304, siv dav (nrog cov khoom siv hluav taws xob zoo), cov khoom siv kho mob, cov khoom siv kho mob, ua liaj ua teb, ua liaj ua teb, nkoj qhov chaw, thiab lwm yam.

Ntxiv rau cov txiaj ntsig ib puag ncig no, stainless hlau kuj tseem yog kev txaus siab, yooj yim kom muaj kev tu siab, yooj yim ruaj khov thiab muaj ntau yam. Raws li qhov tshwm sim, stainless hlau tuaj yeem pom hauv ntau yam khoom txhua hnub. Nws kuj tseem yog lub luag haujlwm tseem ceeb hauv kev lag luam, suav nrog lub zog, kev thauj mus los, kev tshawb fawb, kev tshawb fawb, tshuaj, khoom siv, cov khoom siv.

Cov khoom siv yog qhov kub kub tiv taus thiab siv nyob rau hauv feem ntau cov ntawv thov marine. Cov ntsiab lus Molybdenum ua 316 Stainless hlau hex bolts resistant rau chloside cracking.

Stainless hlau yog ib qho alloy ntawm cov hlau uas tiv taus xeb thiab xeb. Nws muaj tsawg kawg yog 11% chromium thiab tej zaum yuav muaj cov ntsiab lus xws li carbon, lwm yam tsis yog lwm yam kom tau lwm yam uas xav tau. Stainless hlau qhov tsis kam rau corrosion tau los ntawm cov chromium, uas ua cov yeeb yaj kiab passive uas tuaj yeem tiv thaiv cov khoom thiab kho tus kheej nyob rau hauv lub xub ntiag ntawm oxygen

316L, yog qhov kev xaiv zoo dua rau ib qhov project uas yuav tsum muaj ntau tus vuam vim 316 yog qhov ntxim nyiam ntau dua 316l (corrosion nyob rau hauv weld).

ASTM A182 F309H Cov khoom siv stainless hlau flanges cov khoom lag luam yog tsim thiab tsim raws li cov qauv qauv hauv ntiaj teb no.

Cov kav hlau steel tuaj yeem ua kom tawg ntawm lub hauv paus ntawm nws daim ntawv thov. Cov Kev Siv Cov Kav Hlau Hlau yog nyob rau thaj chaw ntawm cov kav dej, kev lag luam raj, cov kab ua liaj ua teb, cov lag luam raj, siv tsheb thiab lwm yam kev lag luam.

Lub Flange Txuas hom feem ntau yog los nrog ob chav, nrog cov ntxhua khaub ncaws thiab cov tshuab ntxhua khaub ncaws thiab qee qhov bolts thiab txiv ntoo txuas rau ib leeg. (Cov yeeb nkab yog welded ntawm flange ua ntej, thiab tom qab ntawd lub valve thiab lwm cov khoom siv tau nruab rau ntawm lub flanges, thiab ces zawm cov flange screws kom ob lub ntsej muag sib txuas ua ke. Flange kev sib txuas yog yooj yim, hloov pauv thiab ua haujlwm-txuag. Thaum cov raj xa hluav taws xob raug kho, cov screws ntawm cov flange tuaj yeem tshem tawm, thiab cov raj xa hluav taws xob sib haum lossis muab tshem tawm. Kuj hloov nrog cov kav dej tshiab thiab cov roj li qub.

Lub 316 cov yeeb nkab stainless hlau khoov tau tuaj yeem yauv ua cov txheej txheem, qhov twg Austenitic Crystal Crystal muaj kev hloov pauv mus rau hauv ferromagnetic martensite. 316L cov hlau yog cov ntau tau ua rau muaj qee qib ntawm Magnetism.

316L 1.4401 tus yeeb nkab stainless hlau yog ib qho kev xaiv yeeb nkab zoo heev thiab cov yeeb nkab ruaj khov siv hauv ntau cov ntawv siv. Qhov no ss s31603 yeeb nkab yog tsim los ntawm cov hlau zoo 316L stainless ua rau corrosion, oxidation thiab staining rau cov chaw hnyav lossis kev siv ntxhov siab.

Ua kom tiav thiab infinitely recaclable, stainless hlau yog lub ¡° ntsuab cov khoom siv. Qhov tseeb, nyob rau hauv kev tsim kho kev ua haujlwm, nws tus nqi rov qab tiag yog ze rau 100%.
