Kev sib piv ntawm 316 stainless hlau yeeb nkab nrog rau lwm qib ntawm stainless hlau yeeb nkab
316 stainless hlau kav, uas muaj molybdenum, muaj zoo heev corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv chloride - nplua nuj ib puag ncig, thiab lawv cov neeg kho tshuab lub zog kuj siab dua li ntawm 304 stainless hlau. Txawm li cas los xij, lawv cov nqi kuj tseem siab dua. Rau cov kev siv dav dav uas yuav tsum muaj kev txhim kho corrosion tsawg, 304 stainless hlau kav yog qhov kev xaiv pheej yig dua; Thaum rau cov dej hiav txwv, tshuaj, thiab lwm qhov chaw hnyav, 316 stainless hlau kav yog qhov kev xaiv zoo tshaj, nrog rau lawv cov kav ntev thiab kev pab lub neej ntau dua li kev them nyiaj rau lawv cov nqi tsis zoo.
SS316 yeeb nkab yog dab tsi?
SS316 seamless yeeb nkab yog hais txog cov yeeb nkab tsis muaj vuam seams lossis fillet welds. Cov kav dej no muaj nyob rau sab nraud ntawm 0.5 ntiv mus rau 16 ntiv tes. Lawv tau dav siv nyob rau hauv marine systems, pulp thiab ntawv, tshuaj industries, thiab lwm yam. Qhov no marine -qib 316 stainless hlau yeeb nkab yuav tsis corrode los yog xeb nyob rau hauv hnyav marine ib puag ncig.
Stainless hlau yog cov khoom siv rau cov kav dej thiab cov kav dej.
Stainless hlau yog ib qho kev xaiv nrov rau cov kav dej thiab tubing vim nws cov corrosion kuj, durability, thiab lub zog . 316 thiab 316L yog dav siv nyob rau hauv ntau yam lag luam rau lawv zoo heev corrosion kuj. Txawm li cas los xij, kev nkag siab qhov sib txawv ntawm cov qib no thiab lwm cov qib stainless hlau yog qhov tseem ceeb thaum xav txog kev siv cov kav hlau stainless rau cov ntawv thov tshwj xeeb.
316L stainless hlau yeeb nkab thiab qib 304 yog lwm qib siv stainless hlau, paub txog lawv cov corrosion kuj zoo heev thiab lub zog. Txawm li cas los xij, piv rau 316L stainless hlau, 304 muaj cov ntsiab lus qis molybdenum, uas txo nws txoj kev tiv thaiv rau pitting thiab crevice corrosion. Yog li ntawd, 316L stainless hlau yog tsim rau harsher ib puag ncig xws li marine thiab tshuaj industries.
Duplex Stainless Hlau
Duplex stainless hlau, xws li hom 2205 qis- carbon steel, muaj kev tiv thaiv corrosion ntau dua thiab muaj zog dua li 316L stainless hlau, ua rau lawv zoo tagnrho rau cov chaw muaj corrosive xws li roj thiab roj ntau lawm. Txawm li cas los xij, duplex stainless hlau tuaj yeem kim dua thiab nyuaj rau kev ua haujlwm, ua rau 316L stainless hlau tus nqi ntau dua -kev xaiv zoo rau cov ntawv thov tsawg dua.
High -Tsub siv
Rau cov ntawv thov uas xav tau qhov kub thiab txias, xws li hluav taws xob tiv thaiv rau lub tshuab hluav taws xob thiab cov tshuab tso pa, hom 310 stainless hlau yog qhov kev xaiv zoo dua vim nws cov ntsiab lus chromium thiab npib tsib xee ntau dua, ua rau muaj kev kub siab heev - tiv taus kub. Hauv kev xaus, kev nkag siab qhov sib txawv ntawm cov qib sib txawv ntawm cov hlau tsis muaj steel thiab lawv qhov tsim nyog rau cov ntawv thov tshwj xeeb yog qhov tseem ceeb thaum xav txog kev siv cov kav hlau stainless. Thaum 316L stainless hlau muaj qhov zoo tshaj plaws corrosion kuj nyob rau hauv ib puag ncig hnyav, lwm cov qib yuav haum rau siab - kub los yog corrosive heev.
