Qhov txawv ntawm 304 thiab 316 Stainless Hlau

Thaum saib ntawm 304 stainless hlau vs 316, nws yog ib qho nyuaj rau pom qhov txawv ntawm lawv. Txawm li cas los xij, thaum tsim khoom nrog 304 vs 316 stainless hlau, qhov sib txawv tuaj yeem loj heev. Khaws nyeem kom paub ntau ntxiv txog ob hom nrov tshaj plaws ntawm stainless hlau.

 

304 vs 316: Dab tsi ua rau lawv nrov?

Cov qib siab ntawm chromium thiab npib tsib xee pom nyob rau hauv 304 thiab 316 stainless hlau muab lawv muaj zog tiv thaiv tshav kub, puas, thiab corrosion. Tsis tsuas yog lawv paub txog lawv cov kev tiv thaiv corrosion, lawv kuj paub txog lawv cov tsos huv thiab huv huv.

Ob hom stainless hlau tshwm sim hauv kev lag luam dav dav. Raws li qib feem ntau ntawm stainless hlau, 304 yog suav tias yog tus qauv "18/8" stainless. 304 stainless hlau yog dav siv vim nws ruaj thiab yooj yim rau hauv ntau hom xws li stainless hlau ntawv, stainless hlau phaj, stainless hlau bar, thiab stainless hlau raj. 316 steel tsis kam rau cov tshuaj thiab ib puag ncig marine ua rau nws muaj kev xaiv nrov ntawm cov tuam ntxhab.

Ob leeg ntawm no 300-qib steels paub txog lawv zoo heev vuam thiab tsim cov khoom, uas muab rau lawv siv nyob rau hauv ntau industries. Cov alloys tsis tuaj yeem hardened los ntawm kev kho cua sov, tab sis lawv tuaj yeem txhim kho lub zog siab los ntawm kev ua haujlwm txias.

 

304 Stainless hlau

Qib 304 stainless hlau feem ntau suav hais tias yog cov hlau tsis zoo tshaj plaws austenitic. Nws muaj cov ntsiab lus npib tsib xee siab uas feem ntau yog nruab nrab ntawm 8 thiab 10.5 feem pua ​​​​ntawm qhov hnyav thiab qhov ntau ntawm chromium ntawm kwv yees li 18 mus rau 20 feem pua ​​​​ntawm qhov hnyav. Lwm cov ntsiab lus tseem ceeb xws li manganese, silicon, thiab carbon. Cov seem ntawm cov tshuaj muaj pes tsawg leeg yog cov hlau.

Qhov siab ntawm chromium thiab npib tsib xee muab 304 stainless hlau zoo heev corrosion kuj. Kev siv ntau yam ntawm 304 stainless hlau suav nrog:

- Cov khoom siv xws li lub tub yees thiab lub tshuab ntxuav tais diav

- Cov khoom siv ua khoom noj khoom haus lag luam

- Piping

- Kub exchangers

-Structures nyob rau hauv ib puag ncig uas yuav corrode txheem carbon steel.

 

316 Stainless hlau

Zoo ib yam li 304, Qib 316 stainless hlau muaj ntau cov chromium thiab npib tsib xee. 316 kuj muaj silicon, manganese, thiab carbon, nrog rau feem ntau ntawm cov muaj pes tsawg leeg yog hlau. Qhov sib txawv loj ntawm 304 thiab 316 stainless hlau yog cov tshuaj lom neeg muaj pes tsawg leeg, nrog 316 muaj qhov tseem ceeb ntawm molybdenum; Feem ntau 2 mus rau 3 feem pua ​​​​ntawm qhov hnyav vs tsuas yog cov lej pom nyob rau hauv 304. Cov ntsiab lus molybdenum siab dua ua rau qib 316 muaj zog tiv thaiv corrosion.

316 stainless hlau feem ntau suav hais tias yog ib qho kev xaiv zoo tshaj plaws thaum xaiv ib qho austenitic stainless hlau rau kev siv dej hiav txwv. Lwm yam kev siv ntawm 316 stainless hlau suav nrog:

-Chemical processing thiab cia khoom.

-Refinery khoom

- Cov khoom siv kho mob

-Cov chaw nyob hauv hiav txwv, tshwj xeeb tshaj yog cov uas muaj chlorides tam sim no
